Windows 7 difference between versions. Differences between Windows versions of operating systems

Microsoft Corporation produces for each version of the Windows software product a certain number of editions (distributions), which have different functions and pricing policies. They have different sets of tools and capabilities that users can use. The simplest releases do not have the ability to use large amounts of RAM. In this article we will conduct a comparative analysis of different versions of Windows 7 and identify their differences.

We provide you with a list that describes various Windows 7 distributions with a brief description and comparative analysis.


The two distributions described at the end of the list will not be considered in this comparative analysis.

This option is the cheapest and too stripped down, so we do not recommend that you use this version.

In this distribution there is practically no possibility of customizing the system to suit your wishes. Catastrophic limitations have been established on PC hardware. It is not possible to install a 64-bit version of the OS; because of this fact, a limitation is imposed on the processor power. Only 2 Gigabytes of RAM will be used.

Another disadvantage I would like to note is the lack of ability to change the standard desktop background. All windows will be displayed in opaque mode (as was the case on Windows XP). This is not such a terrible option for users with extremely outdated equipment. It is also worth remembering that by purchasing a higher version of a release, you can always turn off all its additional features and turn it into a Basic version.

Windows 7 Home Basic

Provided that there is no need to fine-tune the system using a laptop or desktop computer only for home activities, Home Basic is a good choice. Users can install a 64-bit version of the system, which supports a good amount of RAM (up to 8 Gigabits on 64-bit and up to 4 on 32-bit).

Windows Aero functionality is supported, however, there is no way to configure it, which is why the interface looks a little old.

Added features (different from the Initial version):

  • The ability to quickly switch between users, which simplifies the work of several people on one device;
  • The function of supporting two or more monitors is included, very convenient if you use several monitors at the same time;
  • It is possible to change the desktop background;
  • You can use the desktop manager.

This option is not the optimal choice for comfortable use of Windows 7. It definitely does not have a complete set of functionality, there is no application for playing various media materials, and a small amount of memory is supported (which is a serious drawback).

Windows 7 Home Premium

We advise you to opt for this version of the Microsoft software product. The maximum amount of supported RAM is limited to 16 GB, which is enough for most sophisticated computer games and very resource-intensive applications. The distribution has all the features that were presented in the editions described above, and among the additional innovations there is the following:


Professional version of Windows 7

Provided that you have a very sophisticated PC, then you should pay close attention to the Professional version. We can say that here, in principle, there is no limit on the amount of RAM (128 GB should be enough for any, even the most complex tasks). Windows 7 OS in this release is capable of functioning simultaneously with two or more processors (not to be confused with cores).

There are tools here that will be extremely useful for an advanced user, and will also be a pleasant bonus for those who like to tinker with the OS options. There is functionality for creating a backup copy of the system over a local network. It can be launched via remote access.

A function has appeared to create an emulation of the Windows XP environment. Such tools will be incredibly useful to users who want to launch legacy software products. Extremely useful for turning on an old computer game released before the 2000s.

It is possible to encrypt data - a very necessary function if you need to process important documents or protect yourself from intruders who can gain access to confidential data using a virus attack. You can connect to a domain and use the system as a host. It is possible to roll back the system to Vista or XP.

So, we looked at different versions of Windows 7. From our point of view, the optimal choice would be Windows Home Premium (Home Premium), because it provides the optimal set of functions at an affordable price.

More convenient and easier to use

Windows 7 Starter OS simplifies working with laptops, reducing waiting time, the number of clicks, and simplifying the procedure for connecting to the network. Windows 7 Starter combines the latest advances in reliability and speed with the traditional convenience and compatibility of Windows operating systems.

  • Contains features such as Jump Lists, Pin, Snap and Windows Search to make your laptop easier to use.
  • Setting up a home network and connecting to printers and devices has now become much easier.

Based on the latest technological advances

  • Windows 7 Starter supports new hardware and software.

Simplifies home networking

  • Connecting to your home network has never been easier with Windows 7 computers.
  • Easy and fast connection to wireless networks.
  • Internet Explorer 8 provides improved security when browsing the web.
Windows 7 OS Features
  • Desk
    In Windows 7, it's easier to do more things on the desktop.
    • New window manipulations
      Tired of a clutter of open windows? For working with windows, Windows 7 has three simple but very effective functions called Aero Shake, Aero Peek and Snap, which allow you to clean up your desktop.
    • New spectacular background images
      Let's not argue with this fact: we spend a lot of time staring at PCs. Therefore, aesthetics should not fade into the background. That's why Windows 7 includes a ton of new desktop backgrounds, ranging from beautiful to funny. Notice the desktop slide show, which displays a rotating series of images (standard or custom). Your desktop will never be boring.
    • "Superpanel"
      Since Windows 95, the taskbar has served as the starting point for launching programs and switching windows. Times and habits of working with computers have changed. Therefore, in Windows 7, the taskbar was completely redesigned to perform more functions. It now looks much simpler, is more customizable, and makes multitasking easier.
    • Advanced Gadgets
      Gadgets, the small, popular programs introduced in Windows Vista, are more flexible and fun. User feedback was taken into account: the sidebar was removed. Now gadgets can be placed anywhere on the desktop.
  • Home group

    HomeGroup solves the problem of sharing files and printers on your home network. Connect two or more Windows 7 computers and HomeGroup automatically shares libraries of audio, pictures, videos, and documents with everyone on your home network. The new Sharing menu allows you to quickly share personal data.
    Worried about privacy? Us too. Therefore, the HomeGroup function is password protected and is under the full control of the computer owner. You decide which data can be shared and which data can be kept private. You can also set certain files to read-only, so that other users can only view those files (but not change their contents).
    The join a homegroup feature is available in all versions of Windows 7, but you can only create a homegroup in the Home Premium, Professional, or Ultimate versions.

  • Jump Lists

    Jump Lists is a new feature in Windows 7 that lets you quickly jump to documents, pictures, songs or websites that you use frequently. To open the Jump List, right-click the program icon on the Windows 7 taskbar. (Jump Lists are also available in the Start menu.)
    What appears in the Jump List depends on the program. The Jump List for Internet Explorer 8 displays your frequently viewed websites. And for Windows Media Player 12 - frequently played tunes. The file you want isn't showing up in the jump list? You can “pin” any necessary files to it.
    Jump lists are not just for displaying shortcuts to files. Sometimes they also provide quick access to certain commands, such as commands related to composing new email messages or playing music.

  • Snap function
    Snap is a fast and fun new way to resize open windows by simply dragging them to the edges of the screen. Depending on the selected border - top or bottom, left or right - the window will expand vertically, coincide with the borders of the screen, or overlap with other windows. The Snap feature improves the ability to read, organize, and compare information across windows.
  • Windows Live
    It is free software that enhances the functionality of a PC running Windows 7. The core components of Windows Live are for email, instant messaging, photo editing, and blogging. The following free downloads are available:
    • Messenger
      Exchange instant messages with friends and family using your PC or mobile phone.
    • Photo album
      Find, edit and share photos.
    • Mail
      Manage multiple email accounts (eg Hotmail) in one place.
    • Blog Editor
      Create a blog, add photos and videos, and then post it online.
    • Studio
      Turn photos and videos into stunning movies and slide shows.
    • Family Safety
      Monitor and monitor your children's online activities to ensure their safety.
    • Toolbar
      Instant search from any web page.
  • Windows Search
    In Windows 7, search has become even faster and more efficient.

    When you type something you want into the Start menu search box, you'll immediately see a list of matching documents, pictures, music files, and email messages found on your computer. Results are now grouped by category and contain highlighted keywords and text snippets to make it easier to browse your search results.
    Today, hardly anyone stores all their files in one place. That's why Windows 7 also includes the ability to search external hard drives, networked PCs, and libraries. Are your search results too overwhelming? Now they can be limited by date, file type and other necessary categories.

  • Performance Improvements
    Nobody likes to wait. That's why we designed Windows 7 to be faster and always ready to use. Major performance improvements.
    • Standby mode
      Windows 7 also speeds up the process of entering standby, hibernation, and reconnecting to a wireless network.
    • Search
      When looking for any information, you want to get an answer quickly, not wait. In Windows 7, search results appear on the screen faster. Sorting and grouping search results is also much faster.
    • USB devices
    • The first time you connect a portable flash drive or other USB device, Windows 7 gets it ready to use in seconds. If this device has been used before, the connection is even faster.
    • Simplification and less workload
      Unlike previous versions of the OS, Windows 7 allows you to start performance-reducing services running in the background only when necessary. Haven't used a Bluetooth device? This means that the Bluetooth service in Windows 7 remains disabled. Windows 7 also allows you to use less memory than Windows Vista, which improves overall performance
  • Simplified wireless networking
    Windows 7 makes it easy to browse and connect to networks when using your laptop anywhere. Just click the network icon on the taskbar. The View Available Networks feature displays all the necessary parameters for the wireless and wired connection you are using: Wi-Fi, broadband, dial-up, or corporate VPN connection. One click and the connection is done.
  • Windows Media Center
    • Watch, pause and record TV shows.
      Listening to music. View a collection of photos. Entertainment on the Internet. And you can do all this while sitting on the sofa in the living room. So it's no surprise that Media Center is called the crown jewel of Windows.
      In Windows 7, we've made Media Center even better, adding great new features (many of them customer-driven) and graphical touch buttons. Windows Media Center is only supported on Windows 7 Home Premium, Professional, and Ultimate editions.
    • Additional video viewing options...
      Windows Media Center supports a variety of worldwide TV standards and TV tuners (including digital and high-definition standards). Media Center also allows you to play the most common audio and video formats, including 3GP, AAC, AVCHD, DivX, MOV and Xvid. …less waiting time
      Tired of the tedious task of switching TV channels or searching for the desired file in your extensive music library? Instantly move music tracks and display data faster with the new Turbo Scroll feature.
    • Great new slide show feature
      Create stunning photo collages (with background music) with the new slide show editor - great entertainment for parties or family events. Also try out the updated slideshow screensaver. Words cannot describe its stunning graphic effects!
    • Simplified media sharing
      Play TV shows, audio and video files, even if they are stored on a remote storage device. The new HomeGroup feature makes it easier to play media files on any home computer running Windows 7.
    • New gadget, larger preview images
      New Media Center gadget. Quickly view a video clip. More information about the music composition and image. Larger, more convenient sketches. The list of improvements continues to grow.
  • Windows Touch
    Move the mouse away. With Windows 7 and a touchscreen, you can browse online newspapers, flip through photo albums, and randomly open files and folders with just one touch.
    Limited tablet technology has been used in Windows for many years. But in Windows 7 it has been extended for PC in every way. The Start menu and taskbar now have larger touch icons. Well-known Windows 7 programs also support touch controls. The Paint app even lets you draw with your finger!
    Windows Touch is only supported on Windows 7 Home Premium, Professional, and Ultimate editions and allows multi-touch gestures to be recognized (using the right monitor). Need to zoom in? Squeeze your fingers. Need to right-click an object? Tap it with one finger, and then tap the screen with another.

Windows 7 was released for free sale in the fall of 2009 and has since become the most popular of all Microsoft operating systems. Let's try to figure out what innovations and improvements compared to its predecessors brought Windows 7 such popularity and love from numerous users around the world.

Improvements and innovations

A big gift for lovers of the latest technologies was the appearance of multi-touch control support. This technology allows you to control your touchscreen laptop with multiple finger movements at the same time. In addition, it recognizes various user gestures, making operation simple and intuitive. Windows 7 is tightly integrated with driver manufacturers for various devices. Thanks to this, users are relieved of the need to independently determine, search and install the necessary drivers; in most cases, the system will do this automatically.

Fans of older applications will be pleased with the compatibility mode with earlier operating systems, such as Windows XP. This means that users will be able to easily run games that were designed for previous versions of Windows.

The Windows 7 operating system includes a DirectX 11 installation package, which supports a number of new technologies in graphics processing. Users now have the opportunity to fully enjoy the magnificent picture on the computer screen, which is created thanks to improved tessellation mode and support for new compute shaders, as well as expanded ability to render images in multiple threads.

Finally, high-quality operation of the Windows Media Player built into the operating system has been realized, which this time received serial number 12. Previous versions of the program played only a limited number of video formats; to improve the work, the installation of a large number of codecs was required. Users did not like this approach, which is why they increasingly chose software from third-party manufacturers. In the latest version of the player, the list of supported video formats has been significantly expanded.

Windows 7 has received a modified, more convenient and functional taskbar. Now the panel displays only icons without labels, which allows you to fit many more applications on it at the same time. In addition, a “Collapse all windows” button has appeared on the panel.

It is now possible to manage the reserved disk space allocated for system recovery. The user can also determine what exactly should be restored - system settings, changed files, or all together.

Desktop gadgets in Windows 7 are no longer tied to a bar on the left side of the screen. The user can independently move them to any place convenient for him.

Windows 7 has expanded the list of fonts included by default. In addition, the fonts have been redesigned to display various characters correctly. The list of non-Latin fonts available to the user has been significantly expanded.

The Aero interface, known to users from the previous version of the Windows Vista operating system, now supports several design options. It also adds new features that make it easy to manage the location and size of windows on your desktop.

Safety

Windows 7 provides greater security features for your personal computer. Now the user has access to the function of prohibiting the launch of individual applications using the AppLocker service. BitLocker encryption technology has undergone significant improvements and now allows you to encrypt information on removable media. The Windows Firewall has been significantly improved to notify the user when applications are blocked. Thanks to the DirectAccess function, it is now possible to establish a secure connection with a remote server without user intervention.

Editorial

Windows 7 has six different editions, which differ in functionality and cost.

Initial version or Windows 7 Starter characterized by limited functionality, for example, it does not even allow you to change the picture on the desktop. This edition of the operating system is supplied exclusively in the OEM version and, as a rule, was pre-installed on laptops and netbooks.

The next edition is called Windows 7 Home Basic and also has a very limited set of capabilities. It does not support the proprietary Windows Aero interface and Multitouch technology, and has little functionality when working with local networks. Designed for OEM sales and supplies to emerging markets.

The most popular versions were Windows 7 Professional and Home Premium. They are actively sold at retail, and are also pre-installed on a large number of computers assembled around the world. They support all the functions necessary for the average user; the functionality limitations affected only the segment necessary for working in large corporate networks and performing specific tasks.

The maximum range of capabilities is provided by the versions Windows 7 Ultimate and Enterprise. They are identical in functionality, but the first version is intended for retail sales, and the second for deliveries to corporate clients. Windows 7 Ultimate is the top version of the system, which includes absolutely all the features laid down by Microsoft developers.

Hardware requirements

To correctly install the operating system on the user’s computer, it must have the following: minimum characteristics:

  • Processor with a frequency of at least 1 GHz;
  • 1 gigabyte of RAM (2 gigabytes for the 64-bit version);
  • A video adapter with a capacity of at least 128 megabytes (required to enable the Aero interface) and DirectX9 support;
  • 16 gigabytes of free hard disk space (20 gigabytes for the 64-bit version).

The Windows 7 operating system is becoming increasingly popular among users. But this OS was released in several versions at once, and many users do not know which version to give preference to. What are the main differences between versions of Windows 7?

The Windows 7 operating system was released in six versions (editions). Of course, the first difference between the versions of Windows 7 that immediately catches the user's eye is the price. But the difference in price is due to different functionality. Let's take a closer look at each version of the operating system, and then look at the differences between the versions of Windows 7.

Description of Windows 7 versions

Windows 7 Starter. This version only ships with new computers. The initial edition is “stripped down” as much as possible; for example, it does not have a functional part for playing media files with AAC, H.264 and MPEG-2 codecs.

Windows 7 Home Basic. This version of the OS is intended for sale in emerging markets (including CIS countries). In this version, only the basic Windows Aero interface theme is available; a number of functions are not available, such as Shake, Peek, Internet connection sharing, taskbar preview, etc. Playback restrictions in this version are the same as in the Starter version.

Windows 7 Home Premium. This version includes all the features of the Home Basic System, plus Multitouch support, Windows Media Center and additional gaming programs. Also available in this version is the ability to improve handwriting recognition.

Windows 7 Professional. This version differs from Home Enhanced in its ability to use Remote Desktop as the host computer. It is equipped with EFS encryption system. It contains a number of additional processes and AppLocker. The professional version can be downgraded to Windows Vista and Windows XP.

Windows 7 Enterprise. This release is intended primarily for IT professionals to provide them with an opportunity to familiarize themselves with the OS within an organization. This edition is distributed exclusively under a corporate license and has a 90-day free trial period.

Windows 7 Ultimate. As the name implies, this version includes all the available features of the Windows 7 operating system.

What are the main differences between the versions of Windows 7 besides those that have already been described in the brief description of each edition? Let's start with differences between Windows 7 Starter and more “advanced” versions operating system. This edition does not have a 64-bit version, it does not support the Windows Aero interface, the ability to quickly switch between users, the desktop manager, the Windows Mobility Center, or the ability to change the desktop background.

All these functions are already present in the Home Basic version, which, however, lacks a number of other functions. The differences between Windows 7 Starter and Home Basic versions from other OS editions are as follows:: Inability to create a homegroup (you can only join), lack of support for multiple monitors, lack of Multitouch and improved handwriting recognition, lack of Windows Media Center, additional games, the ability to act as a Remote Desktop host, support for multiple physical processors. These features are present in the following editions of Windows 7.

Also Windows 7 Starter, Home Basic and Home Premium do not have a Windows XP emulator, EFS data encryption system, location-based printing, or the ability to connect to a Windows NT domain. These versions cannot be downgraded to Windows XP or Vista. And only the Corporate and Maximum versions support a multilingual user environment.

The differences between Windows 7 versions also include support end date and maximum RAM size for 64-bit versions. Support for all versions except Professional and Enterprise ends on January 13, 2015; Professional and Enterprise versions are supported for 5 years longer. Regarding amount of RAM, The Starter edition supports up to 2 GB, Home Basic - up to 8 GB, Home Premium - up to 16 GB, and Professional, Enterprise and Ultimate - up to 192 GB (all figures are for 64-bit versions, because the 32-bit version any OS supports no more than 3.25 GB of RAM).

Here are all the main differences between Windows 7 versions. Version selection depends on the configuration of your computer, the minimum functionality you need and, of course, the amount of money you are willing to pay for the operating system.

Installing the system on a PC is very simple and generally does not differ from installing Windows Vista. And it should be noted that the system requirements for a 64-bit system are somewhat high - it can run on 1 GB of RAM. Below in the article we will discuss the pros and cons of 64-bit versions, as well as “which is better – a 32-bit or 64-bit version.”

But you can see such signs (or similar ones) on any site where Windows 7 is mentioned. And, frankly, for the average user they are not very informative: it looks like you need to take the Maximum version (you won’t be able to buy the Enterprise version - this version is not for free sales). But do you need it? Let's try to figure it out...

What to install - 32-bit or 64-bit?

Here we are considering the situation that we install on a home computer to solve typical household tasks: watching movies, simple work (like typing in MS Word), the Internet, games.
Most sites advise installing the 64-bit version, citing the fact that it “works faster.” Opponents of the 64-bit system motivate their position with a “problem with drivers.” In fact, now there is practically no such problem - you can almost always find a 64-bit driver for more or less modern equipment. In some cases, 32-bit ones are also available - but this risks slowing down the system or even causing it to fall into the “blue screen of death”. Therefore, it is better to install only 64-bit drivers.
In fact, for home computers the performance increase is not as significant as we would like; it is clearly noticeable in mathematical calculations, for example, but in everyday life it is practically unnoticeable; moreover, given that most programs are now 32-bit, it can happen slowing down your computer. This is due to the peculiarity of executing 32-bit programs on a 64-bit system. Therefore, at the moment it is more desirable to install a 32-bit system (since a 32-bit analogue of a 64-bit program can almost always be found, and the opposite is not always true).
For home computers, there is one exception to the rule - you must install a 64-bit OS if the amount of RAM on your computer is more than 3 gigabytes. 32-bit systems cannot address memory larger than 4 GB, in fact - no more than 3 GB (memory allocation feature). You can enable "advanced" addressing (PAE), but this is a "crutch" that does not always work.
Conclusion: if you have 4 GB or more, install 64-bit Windows 7, in other cases install 32-bit.

Deciding on the edition of Windows 7

Not everything is clear here - even home users have different needs. Therefore, we will explain the features of each edition, based on the table above. As you can see, in the table the “features” of the system are grouped in such a way that the subsequent edition contains all the features that were in the previous one (unlike the table on the Microsoft website - it is grouped there by categories (“entertainment”, “opportunities”, etc. .d.), but comparison is somewhat difficult. Therefore, for those who need to look by category, you are welcome here:
http://windows.microsoft.com/ru-RU/windows7/products/compare?T1=tab20
All editions allow you to simultaneously run an unlimited number of applications (as long as your computer resources allow).
Note. It is recommended to open all links to the Microsoft website that will be in the article in Internet Explorer.

Windows 7 Starter

Improved taskbar and jump lists is a feature that allows you to quickly jump to frequently used files. The contents of the jump list depend on the specific program. To view the Jump List, you can right-click on the program icon in the taskbar or call it from the Start menu:
The improved taskbar is a changed appearance (compared to previous versions of Windows) with improved functionality (which is expanded in more “advanced” editions).
Windows Search: A tool for finding files on your computer. Includes indexing services to speed up file searches. Available in the upper right corner of the window.
Joining a HomeGroup: provides the ability to join a computer to a homegroup. HomeGroup is a tool that makes it easier to set up shared access to files and folders, as well as printers on your home network (that is, between computers in your apartment/house). Readers of MirSovetov should understand that Windows Starter only supports joining a homegroup, but not creating them!
Archiving and recovery: a program designed to archive important files (both yours and system ones) so that they can be restored if necessary. You can choose which files and folders you want to archive. You can also make an emergency copy of the entire system (a snapshot of the system) with installed drivers, programs... So that if something happens, you have fewer problems with reinstallation.
Support Center: built-in program for displaying important Windows notifications that require user attention. These notifications pop up mainly when there are any violations in the system that threaten its security or normal functioning, as well as when there are updates on the Microsoft website. The support center also offers ways to solve problems and routine maintenance of your computer, allowing it to maintain normal operation.

Device management: When you connect a device, a window may appear that groups the most frequently used functions for that device. For example, if you have an MFP (printer-scanner-copier), then when you connect it, various scanning and printing options may be displayed. In earlier versions of Windows, this was separated into different menus, which you still need to get to. An example of this function on the Microsoft website:

Streaming media files, including Play To technology: Streaming is when a file is played on one computer (broadcast server), and other computers act as receivers. It turns out something like a radio broadcast, but on a local network. PlayTo technology allows you to choose which computer to play the specified file on, i.e. allows you to personalize your broadcast. You can admire the PlayTo technology by downloading a demo video from the Microsoft website:
http://windows.microsoft.com/ru-RU/windows7/products/features/play-to
Bluetooth support: support for Bluetooth devices.
Basic set of games: standard set of games (Klondike, Minesweeper, Spider...).
Credential Manager: allows you to work with user accounts (add, change name, set password and other account-related features).

Aero Snap: a very useful feature, according to MirSovetov: quick resizing of windows when dragging them to the edges of the screen. For example, when you need to view two Word documents side by side at the same time: previously you had to adjust the sizes manually, now you just need to drag one document to the left and the second to the right side of the screen. When you “drag” the windows from these positions, the windows will restore their former size. Oddly enough, it is available even on systems that do not have an Aero interface.

In addition, in the Initial version you cannot change the wallpaper on your desktop. The initial version is usually supplied on netbooks, but on them it is quite possible to replace it with some more powerful edition. There are also restrictions on running some applications, for example, some games do not run on this OS.

Windows 7 Home Basic

Includes everything that is in the Primary, and in addition to this a number of possibilities.
"Live" thumbnails in the taskbar: When you hover and hold the cursor over the program icon in the taskbar, a window thumbnail appears showing what the program is currently doing. Video playback can even occur in this window. One program can have several thumbnails if several windows are open in it. In short, these are something like screenshots of a window in the taskbar:

Fast user switching: support for switching to another user without first closing all windows and programs of the current user.
Connect to wireless networks on the fly: When you left-click on the wireless networks icon in the taskbar, a list of available wireless networks (and information about them in tooltips) that you can connect to is displayed
Internet Connection Sharing: the ability to access the Internet of computers on a local network through a computer on the same network connected to the Internet.
Multiple monitor support: displaying the Windows desktop and programs on other monitors connected to this computer; There are various display options. You can access these settings by right-clicking on the desktop and selecting “screen resolution”:

In this case, the system has one monitor. If there were several of them, then next to the monitor with the number 1, a monitor with the number 2 would appear, and in the “screen” drop-down list you would be asked to select the desired monitor.
Windows Mobility Center: This is for laptops and netbooks, allowing you to access quickly used tasks typical for this type of system:

This edition does not support equipment for displaying presentations (the ability to connect projectors).

Windows 7 Home Premium

Includes everything that is in Home Basic, plus some functionality on top of that.
Aero Glass and advanced navigation in Windows (Aero Shake and Aero Peek, Aero Snap): Aero Glass is a translucent window display style and animation, with the ability to customize translucency, colors, etc. "for yourself." Aero Shake hides all windows except the selected one. To restore all windows, simply shake the active window. Demonstration (video):
http://windows.microsoft.com/ru-RU/windows7/products/features/shake
Aero Peek – “X-ray” for windows – allows you to look “through windows”, while the outlines of windows remain on the screen, but their contents disappear (except for the selected window). Demonstration (video):
http://windows.microsoft.com/ru-RU/windows7/products/features/peek
Windows Touch (touch and handwriting): Designed for tablet computers. Allows you to work with the system by clicking on interface elements on the screen.
Create a homegroup: what is a home group - see the corresponding paragraph in the description of the capabilities of the “initial” edition. In this edition, in addition to joining, you can already create home groups. The fundamental difference is that in the “initial” edition it was impossible to select files and printers to which you want to share access in this way, but in this version you can.
Windows Media Center: a program for quick access to multimedia functions of Windows: watching and recording TV shows, viewing videos and photos, listening to music... Optimized for use on devices with touch screens.
Playing and editing DVD video: If you can play a DVD on any edition, providing the appropriate codec if necessary, then here this codec is already available “out of the box”.

Extended set of games: Chess, mahjong, backgammon and others are added to the standard games.
Scissors, Notes:“Scissors” not only allows you to select any area of ​​the screen and take a screenshot only from this area. Sticky notes are like “sticky notes” on your desktop for memory. This function will be useful for MirSovetov readers who own tablet PCs - you can take notes by hand.
Windows Sideshow (on secondary display): technology for receiving and displaying data from a computer on other displays. For example, displaying a photo from a computer in a photo frame.

Windows 7 Professional

Includes all the features of Home Extended, with a number of others added.
Location-based printing: Let's say you're using a laptop and connecting it to the network at work. There is a printer at work, there is a printer at home. Previously, you had to reconfigure the printer each time or, at best, select the appropriate default printer. With this feature, Windows remembers which network the printer is connected to and automatically restores the settings for it when it reconnects to that network.
Joining a domain and group policies: allows you to configure group policies (sets of rules in accordance with which the Windows environment is configured, typical for multi-user systems) and the ability to enter a computer into a domain (a domain is a group of computers with the same security policies).
Remote desktop connections (host): allows you to remotely connect to a computer and work on a remote computer as if you were behind it.
The prefix "host" means that the computer can act as the one to be connected to using the remote desktop feature.
Advanced archiving (network and group policies): everything is the same as in regular archiving, but to this is added the ability to archive network settings and group policies.
Encrypting File System (EFS): allows you to encrypt your files and folders from other users (when using the NTFS file system). How and why to encrypt is, rather, the topic of a separate article.
Windows Mobility Center: a presentation mode has been added (what a “mobility center” is – see the description of the Home Basic Edition) makes it possible to display an image on a projector:

Offline folders: the ability to automatically copy the contents of server files to the local computer disk; the user will be able to access the files even if the server on which they are stored goes offline. Periodically, Windows synchronizes files in offline folders with the contents of files on the server.
Windows XP Mode: allows you to run the Windows XP operating system in a Windows 7 environment. And work with it as if you had it installed - i.e. install programs there, run games for XP, etc. At the same time, there is a “transparent” connection with Windows 7: for example, you can easily copy files from Win7 to Win XP (and vice versa) by simply dragging them from the Win7 desktop to Win XP and vice versa.
This function can also work as a means of launching programs in the Windows 7 environment: the Windows XP window does not open, but all conditions under which the program would work on real XP are emulated, which is not achieved by the options on the “compatibility” tab. To be fair, it is worth noting that there are few such programs.
This feature requires installation of a virtualization tool.
Note for a professional. Starting with this version, the distribution includes such useful snap-ins as lusrmgr.msc (Manage local users and groups), gpedit.msc (Group Policy Editor), secpol.msc (Security Policies).

Windows 7 Ultimate and Enterprise

The versions include everything that is in the Professional version, and in addition:
BitLocker and BitLocker To Go: These are tools for protecting and encrypting data on hard drives (BitLocker) and USB storage devices (BitLocker To Go). A conversation about how it works and how it is configured is beyond the scope of this article. Most home users don't need these programs (unless you work with data that you don't want anyone to access).
AppLocker: This is an addition to group policies that determines which applications can/cannot run on computers on the network. A tool for administrators, controlled from the Windows Power Shell console, the average user has absolutely no need for it, unless they prevent children from playing toys. But this is a “cannon against sparrows” - there are more convenient means.
DirectAccess: allows you to gain access from home to the organization’s internal network using a special server. Again, the average user does not need it.
BranchCache: caches data from remote servers on local network resources. Saves working time on downloading files, sometimes improves the performance of web applications. Why is this on a home computer?
Multilingual user interface (language packs): allows you to install localization packages, as a result of which each user can select their own native language on one computer. Relevant for transnational companies.
"Corporate" search: search on the organization's network, incl. in databases, etc., with a high degree of compliance of the returned result with the requested one.
Improvements in virtual deployment environments (VDI): a technology that allows you to save on application licensing (and some other things) - when virtual computers are deployed on one server, users work with them in the same way as if they were “real”.
Booting from virtual hard disks (VHD): a virtual hard disk is a file, one might say, an image, which has its own file system, operating system, data, etc. Mainly used in virtual machines. But with this function you can boot Windows 7 from such a file. Allows you to have several copies of Windows, independent of each other, on one “real” (physical) hard drive without any special costs.
Yes, I would like to note that Windows Media Player is available in all versions of Windows 7. Also, recently it has become possible to select the desired browser when installing Windows 7 (the so-called “browser selection dialog box”), almost all popular browsers are available to choose from (Opera, Chrome, Firefox, IE...).

Which version of Windows 7 should I choose?

This is where we will finish the description of the “tricks” of the various editions. Let's summarize. But before that, let’s divide the user audience into groups. The division is very arbitrary and characterizes the main range of tasks that the user solves in everyday life. The division itself was somehow imperceptibly derived by the author over 7 years of work in the IT field, perhaps it is somewhat subjective:
  1. Beginners / Regular users. They are either just starting to learn the basics of working with a computer, or they use the computer as a typewriter and for surfing the Internet. They periodically watch films, listen to music;
  2. Advanced users/Interested. “Just working” with a computer is no longer enough for them; they are looking for ways to make this work faster, more convenient, and easier. And also in many cases they try to understand “how it works” and “what else can be done”;
  3. IT professionals / students of IT specialties. For them, computers are a profession. They use it to do everything - from hammering nails with a computer to developing large control systems and security systems. They tend to require more features from the operating system.
For category 1, the best choice would be Windows 7 Home Premium - it has everything you need for work and entertainment and even a little more. At the same time, you don’t overpay for functionality you don’t need, which you won’t use anyway.

Windows 7 Ultimate can be recommended to those who work in a large organization as at least a system administrator or want to encrypt data using BitLocker out of the box, without having to worry about purchasing and configuring third-party software, which is not always able to work as expected (i.e. e. may not be compatible with this version of Windows).
Why don’t we recommend “Elementary” and “Home Basic” to any of our readers? Because, in our opinion, these are slightly inferior systems, greatly reduced and devoid of useful functions that are often needed in the modern world. It's just a matter of saving money. In addition, the “Initial” edition is not sold in Russia and the CIS.
All of the above is not presented as truth in the highest authority, the choice is yours, given that many do not buy Windows, but download from various Internet resources - there is no question of saving money here. Well, those who honestly buy an OS should approach the choice of editors responsibly, because the money is yours and overpaying for something that you will never use is stupid, to say the least.
Exceptions (where would we be without them!). If you have a tablet computer or a device with a touch screen, it is better for you to install at least Windows 7 Home Premium. If you need a presentation function (seamless connection of a projector), then it would seem that your choice is “Professional”? Not necessarily. Of all the features of this edition, you only need one function - and pay almost double the amount for it? Wouldn't it be easier to use a third-party utility - it comes with almost every projector and laptop?
