    What is the use of svchost.exe service in Windows OS? Why there are so many instance of svchost.exe is running in background of Windows OS?

    My Windows system is getting very slow these days after I work for sometime and when I checked in the Task manager I found that most of memory usage is by the svchost.exe service. So I was thinking to kill the process but the problem is it is a System service which is running in the background, am quite not sure if I can kill it. So can you tell me if it will be ok if I kill the svchost process? Why there are so many instance of svchost.exe is running in the background of Windows OS?

    Hiiiiiii
    svchost.exe is a generic host process name for services that run from dynamic-link libraries, but the problem is that you cant launch a .dll file directly from Windows, it has to be loaded up from a running executable (.exe). Thus the svchost.exe process is used.you can also disable it in task manager select all process of svchost.exe in taskmanager and
    1)click on properties ,select the Services tab, where you can choose to stop one of the services if you choose.
    2)Open up Services from the administrative tools section of Control Panel, or type services.msc into the start menu search or run box.
    3)Find the service in the list that youd like to disable, and either double-click on it or right-click and choose Properties.Change the Startup Type to Disabled, and then click the Stop button to immediately stop it.
    Thanks and Regards

    -svchost.exe is a generic host process name for services that run from dynamic-link libraries.
    -It is essential in the implementation of so-called shared service processes, where a number of services can share a process in order to reduce resource consumption.
    -It hosts multiple window processes.
    -These are many because if every single service ran under a single svchost.exe instance, a failure in one might bring down all of Windows so they are separated out.

    Hi,
    svchost.exe is a generic host process executable file, that helps running those library files, files with .dll extention, which are not self executable.
    Sometimes a lot of host processes run in the background to encroach all the processors resource which makes the system slow due to non availability of process for other programs or tasks.
    Virus, malwares gets attached to the svchost.exe files and corrupts to not perform its entitled duties but run insted unjudiciously for this inconvenience.
    Check the virus and remove them to clean the system and free resource from ghost processes.

    Thank you.

    Dear friend,

    You can kill the unwanted svchost.exe services to increase the performance of your Windows operating system. But you have to do this manually by checking all the services running on this file in the following way:
    > Open task manager and go to processes tab. Search for the svchost.exe file and right click on it.
    > Select-- go to service-- from the list appeared.
    > In the new window, right click on the service (the highlighted services only) you want to stop and then choose -- stop the service--.
    > You can stop unnecessary processes such as networking services if you are not using any networking, depending upon your requirement. You can reactivate the services in the same way. After restarting your PC, all the services reactivate themselves automatically. If you face any problem you can do this. You can use trial and error method.

    Thanks!
