If Windows often crashes on your computer and laptop, and you are tired of going to the official service center on the other side of town and you want to reinstall the operating system yourself, then this article is for you.

Preparation

If you need to reinstall your operating system, but have little time, first of all, thoroughly comb through all the corners of your hard drive for the files you need. After all, the Windows 7 installer, during the installation of a new operating system, can easily erase all your data from your computer, and restoring them will be almost impossible. So, you have saved all your data to a separate medium. Now we can start transferring Windows installation.

Let's start the installation

We insert the Windows 7 installer recorded on the disk into the drive and restart the computer. If everything is configured correctly in the BIOS, the message “Press any key to boot from disk” will appear. If this is not the case, then restart the computer again and quickly begin pressing the F2 button or another one necessary to enter the BIOS.

After you have entered the BIOS, your task is to change the order of devices from which the personal computer boots. In the "Boot priority device" sub-item, set your drive to first place, save the settings and leave the BIOS menu.

If you did everything correctly, then when you reboot you will be prompted to run the Windows 7 installer from the disk. You can press any button, it doesn’t matter which one. Press the button and the installer starts launching.

After a short preparation of the files, the Windows installer will give you start window, in which you will need to select the default languages ​​​​in your future operating system. We set “Russian” everywhere and click next.

After confirming your consent with license agreement, the Windows 7 installer will prompt you to select an operating system installation option.

  • Update. Allows you to restore the system to its original state without losing files and data. It is best to use it only in cases where you may have accidentally deleted any system files and thereby disrupt the operation of the operating system. This is only possible if you install Windows from the same disk as the previous system.
  • Full installation. This is the recommended setting. He has one huge drawback- it is able to completely delete data from your computer. However, this is also a plus if you look at it from the point of view that all viruses will also be removed. And if we draw an allegory, what will float better - a new ship or a vessel on patches?

Disk partitions

Click full installation. Windows Installer will prompt you to select a disk partition on which you can install your operating system.

  • If you are reinstalling the system, first format the partition on which it was installed. previous version operating system.
  • If you install Windows on a clean, new hard drive, it is recommended to create a new subkey specifically for the operating system. Modern hard drives have enough large volume, so go to the disk settings and click “Create”. Remember that the space for the operating system is not only the space for the files of the shell itself, but also your desktop. If you are used to storing files in folders directly on your desktop, then feel free to allocate approximately 100~150 gigabytes of memory for the OS.

Remaining free space You also need to mark it on your hard drive. Therefore, click “Create” again and indicate all the remaining free space. Congratulations, your disk is ready to install the operating system.

Reinstalling Windows 8

When purchasing a laptop or personal computer in the store, on new models it will be pre-installed latest version operating system. Unfortunately, in present moment This is Windows 8, considered a failure even by the developers themselves. And this is where the problems begin. The fact is that the service or the store itself will not supply the user with the operating system he wants for free. A person pays for a laptop with Windows 8, and that’s what he gets. And even if he takes it to the service center, they will again ask him to give it an “eight.” The fact is that stores take advantage of the fact that replacing Windows 8 with Windows 7 is very troublesome, and for some manufacturers it is almost impossible, so people continue to suffer from freezes and critical errors new operating system. However, there is always a way out. Let's look at how to run the Windows 7 installer on a laptop with eight preinstalled.

First of all, go to the BIOS. To do this, press the required button when loading the OS. We squeeze it, not push it. On many laptops, the time allotted for this operation is about 200 ms.

In the BIOS control panel, disable reinstallation protection. To do this, in the “Security” tab, set the “Secure Boot” parameter to the “Disabled” position. In the "Advanced" tab, go to the system configuration and install there " Boot Mode"to the "Legacy" or "CSM" mode. Save and exit the BIOS. Now, having done the same operations as with normal installation Windows 7, we reach the window with choice of hard disk. There we can safely delete all sections and create new ones for ourselves.

Nuances

When reinstalling Windows 8, a situation may arise that the Windows 7 installer does not work. This may be due to the fact that Windows 8 initially uses a different encoding standard. Therefore, if the seventh axis refuses to automatically change the standard, but simply gives an error, then we will have to do it ourselves.

Having reached the stage of forming disk partitions, press Shift+F10. In the line that appears, enter several commands in a row. After each command, press Enter.

diskpart -> sel dis 0 -> clean -> convert mbr -> exit -> exit

Thus, we converted disk 0 to MBR format. If you have several hard drives, repeat this operation for each, replacing 0 with the corresponding disk number.

Completing installation

Once all the previous steps have been completed, the problems have been resolved and the hard drive has been prepared, you can safely click “Next”. The operating system will be copied, unpacked and installed. Be sure to ensure that your computer does not lose power while installing the operating system. If you think this might happen, it's better to use a UPS.

Upon completion of the installation, the installer will launch a chain of dialog boxes designed to general settings personal computer. You will need to enter the user name, computer name, come up with a password if necessary, and most importantly, activate the operating system.

After all the steps, it is highly recommended to update all drivers. Without them, some ports on a laptop or computer may not work at all. Use the utility Driver Booster 2. After updating, restart your computer. Your operating system is ready to use.

Applications

Installing applications on the operating system Windows system does not require a software installer for Windows 7. All necessary information for installation is contained in the installer file of the supplied product. You don't need to worry about installing the program.

With your own hands

If you decide to try your hand at programming and, moreover, already have a program you have created, you may need information on how to make an installer. For these purposes, there are ready-made products from various companies.

  • Install Shield Wizard. You can often find this logo on official software products. A reliable program that allows you to encode all the source information will help you compile your own installer.
  • More simple option For amateurs, Actual Installer may be useful. A freely distributed program for creating installers.

In general, whether you use installers or try to create them is not the point. Remember that without experimentation and practice you will never succeed.

You rarely have to deal with applications distributed as MSI installers, but for some reason they cause the most problems for users. The most common one is the error “Could not access the installer service.” Windows Installer", and you can encounter it at any Windows versions. In most cases, the error occurs due to incorrect work the corresponding service - Windows Installer or msiserver. Most often, when checking, it turns out to be disabled. You can make sure that everything is in order with the service as follows.

Open the service management snap-in with the command services.msc and find the “Windows Installer” item in the list.

By default, this service is in an inactive state, and its startup type is selected as “Manual”.

In theory, when you run the executable MSI file, it should be automatically activated, but this will not happen if for some reason the startup type is set to “Disabled”. You need to change the settings by selecting the “Manual” option in the drop-down list, but most likely the settings will be inaccessible, which is typical for Windows 10. You will have to work around it.

Open the HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/msiserver key in the registry editor and change the Start value from 4 to 3, and then reboot.

The startup type will change to Manual and the startup button will become active. To set the startup type to "Automatic", the Start value must be changed to 2. Since the msiserver service is a dependent service, we recommend that you also check the status of the service " Remote call RPC procedures". It must be running and the startup type must be “Automatic”.

It may happen that the Windows Installer service will not appear in the list at all. The most likely reason for this is damage to the data responsible for it in the registry. In this case, try to restore it by merging the Windows_Installer.reg file, available at https://cloud.mail.ru/public/2eVp/mWmQUP8FG. After applying the tweak you will need to restart your computer. You can also update your operating system to the latest build, if that's an option for you.

It's also a good idea to check your Windows Installer policy settings. Use the gpedit.msc command to call the editor local policies and follow the chain Computer Configuration - Administrative Templates - Windows components- Windows Installer. All policies must have the status "Not Configured".

Similarly, check the settings in the User Configuration section.

Finally, restore normal work Windows Installer service can be done by manually re-registering it. To do this, open the command line as administrator and sequentially execute the commands specified in this text file- https://cloud.mail.ru/public/9bBp/bYNiRVB82. After re-registration service, the computer should be rebooted, and then the installer service should be started net command start MSIServer, if suddenly for some reason it does not start on its own.

I have had a couple of laptops damaged by “optimizers” and filled with programs installed together with them. Inexperienced users still believe in “optimizers” and don’t look at the checkboxes when installing, but that’s not the point. After cleaning, I started updating the software and unexpectedly (for the first time in my life) encountered the following error during installation:

The Windows Installer service could not be accessed. Windows Installer may not be installed. Contact support for assistance.

The error occurred during installation from msi (for which the service itself, among other things, is responsible). Maybe the service is turned off? We go to Control Panel - Administration - Services and do not find the one we need in the list. Did the optimizers optimize? We google for a long time, read a bunch of advice that doesn’t apply, study the question along the way and come to the following:

  1. Let's check whether Windows Installer actually exists on the system. Press Win+R, in the “Run” window that appears, write msiexec, click OK. If the Windows Installer Help window opens, the service is in place. But why is it not in the list of services?
  2. Let’s re-register the service in the system: open the “Run” window (Win+R) and write msiexec /unregister , then “Run” again and msiexec /regserver .
  3. Go to Services (Control Panel - Administrative Tools - Services), find “Windows Installer” (Windows Installer for the English version).
  4. Everything is ok. We check by installing from msi. If not, then my method did not help you, Google will help.

Some users are faced with the fact that applications do not install and a message pops up saying that windows installer not installed or running. How to solve this problem and install the necessary utility will be discussed in this article.

Checking if the service is running

One of the main reasons for such failures is stopping the installer service. To check this, you need to launch the Run utility, which can be done through Start, and then enter the services.msc command into it, which can be seen in the image.

After this, a window will open in which all services, both active and not, will be displayed. You need to find a service called " InstallerWindows" and open it. The parameters should be the same as in the picture.

In seven you can try changing the startup type to automatic; in eight this action is not available. If the user changes the startup type, the device should be rebooted after this. However, you should try to run it in both versions. Then you need to start installing the program again.

Correcting errors manually

If the previous method did not help correct the situation, then you can re-registration of the service on one's own. To do this, you will need to run the console as an administrator. This can be done through the Start menu. IN command line will need to enter the following operators:

Such commands are required for 32-bit operating system. And these will need to be used for 64-bit Windows. After completing the work you will need to make restarting the device and try to install again necessary utilities. The installer service should start.

Using the registry to reset parameters

It is also possible that the error lies in the registry. You can use one of the programs to recover records, but it is not a fact that they will help. It is better to open the registry editor yourself and find the following entry there:

This folder should check the ImagePath entry, the value of which should be the same as in the image. If this is not the case, then it is worth editing it.

For 64 bit operating systems, is also worth doing file checkWOW64. There should be hexadecimal system calculus, and the value must be 0.

After editing the registry, you should restart your computer and check its functionality.
