Easy Hack: Hacker secrets for simple things. Disabling unnecessary Windows services See what "Simple Service Discovery Protocol" is in other dictionaries
Sometimes we don’t know that we have services running on our PC that can be safely disabled.
They affect performance and, most importantly, create additional vulnerabilities.
The list contains services and a brief description of functionality. Services can be safely disabled, since the dependency is taken into account, unless of course you need their functionality.
And so ctrl +r => services.msc and disable:
Start / Run / write the following in the command line: services.msc / click OK.
Control Panel / Switch to Classic View / Administration / Services.
Disabling services (of course, not all, but only unused ones) in the Services (local) window that appears is simple: click on the service you are looking for, and a proposal to stop or restart the service will appear on the right. Read the information provided and click “disable”.
I remind you once again: you should disable these services if they are not needed. That is, if you are the owner of a home computer that is not connected by a local network to other computers, which is the case in most cases.
Which Windows services should I disable?
Here is a list of Windows Services that are considered potentially dangerous, that is, making your computer vulnerable to external intrusions:
Remote Registry - allows remote users to change registry settings on your computer; If you stop this service, the registry can only be modified by local users running on the computer.
Terminal Services (TermService) - in general, this service is designed for remote connection to your machine over the network with the ability to manage it. It allows multiple users to connect interactively to a computer and displays the desktop and applications on remote computers. It is the basis for Remote Desktop, Remote Administration, Remote Assistance, and Terminal Services.
Messenger Service—Sends administrative alerts to selected users and computers. In the absence of a network (and, accordingly, an administrator) it is absolutely useless. It is also advisable to disable it in order to prohibit net send messages to hide your computer from automated spam mailings. This service has nothing to do with the Windows/MSN Messenger program.
SSDP Discovery Service (SSDPSRV) - Enables discovery of UPnP devices on your home network. UPnP, or Universal Plug and Play, is a universal automatic configuration and connection of network devices to each other, as a result of which a network (for example, a home network) can become accessible to more people.
Alerter—Sends administrative alerts to selected users and computers. At home, the service is not needed.
Task Scheduler (Shedule) - allows you to configure a schedule for automatic execution of tasks on your computer. Automatically launches various applications, programs, scripts, backup function at the time you schedule (by default, these tasks can be found here: Start / Programs / Accessories / System Tools / Scheduled Tasks). If you do not use this feature, disable this service. In addition, the vulnerability of this service is used by some viruses for autoloading.
However, be aware that some antivirus programs, such as Symantec or McAfee, use this service for timed updates and scheduled system scans. So in this case, you should not disable the task scheduler.
NetMeeting Remote Desktop Sharing (mnmsrvc) - Allows verified users to access the Windows desktop over a corporate intranet using NetMeeting.
Remote Desktop Help Session Manager—Manages Remote Assistance capabilities.
Telnet (Telnet)—Allows a remote user to log on to a system and run programs, and supports a variety of TCP/IP Telnet clients, including computers running UNIX and Windows operating systems. Provides the ability to connect and remotely work in the system via the Telnet (Teletype Network) protocol using a command interpreter. This protocol does not use encryption and is therefore very vulnerable to attacks when used over a network. If this service is stopped, the remote user will not be able to run programs.
Other services that may not be used on your computer, but at the same time load memory, significantly slowing down the loading and operation of the system:
Automatic Updates - Enables downloading and installing Windows updates. If you don't use this service, disable it.
Secondary login – allows you to run processes as another user. If there is only your account in the system (not counting the administrator account), you can also disable it.
Print Spooler - Responsible for processing, scheduling, and distributing documents to be printed. If you don't have a printer, turn it off.
Help and Support - If you don't use the Windows Help menu, turn it off.
Computer Browser - maintains a list of computers on the network and provides it to programs upon request. If you do not have a local network, then disable this service.
Uninterruptible power supply - if you do not have an uninterruptible power supply, you can disable this service.
Be careful when deciding whether to disable a particular Windows service. Make sure that the operation of a particular service is not required for the functioning of any services, applications or devices that you need.
Before disabling a service, look at which services may depend on it.
To view dependencies, open the service properties and go to the last tab - “Dependencies”. The top list will show the services on which the functioning of the selected one depends. The lower list, on the contrary, contains services that depend on this one.
If there are no dependencies at all, then the service can be disabled without concern.
Simple Service Discovery Protocol(English) , SSDP ) is an expired draft Internet standard (Internet draft) IETF, written by Microsoft and Hewlett-Packard. This protocol is the basis of the Universal plug-and-play discovery protocol.
SSDP describes a mechanism by which network clients can discover various network services. Clients use SSDP without prior configuration. SSDP supports multicast discovery, server notifications, and routing. This service enables discovery of UPnP devices on your home network. For example, a TV with DLNA/UPNP support finds media servers on the local network using this protocol. Home routers are also typically discovered by computers using SSDP (to display information about routers and media servers in Network Neighborhood, these devices must also support the HTTP protocol, since SSDP provides devices with an HTTP link to the device's control node) .
SSDP uses XML UDP packets in both unicast and multicast for service advertisements. The multicast address 239.255.255.250 is used.
In the Windows operating system, no other services are required for the normal functioning of the SSDP Discovery Service. The “Universal Plug and Play Device Host” depends on the operation of this service.
