What is svchost.exe in Windows? Why do I see multiple instances of svchost.exe processes running in my Task Manager? How do I find out basic information like the name and description for each svchost process? This article will attempt to answer these questions.
What is svchost.exe in Windows 7?
Svchost stands for Service Host. It is a .exe executable operating system critical file which is located in the System32 folder. When Windows starts up, it checks the Windows Registry and makes a list of Services or group of Services that it has to load.
You therefore see multiple such svchost.exe running at the same time. This grouping of services also assists in better control and debugging should the need arise. Services run in svchost are implemented as dynamically-linked libraries or dll files.
You can see all these svchost.exe groups under the following registry key:
To view the list of services that are running in Svchost, open an instance of command prompt, type Tasklist /SVC and hit Enter.
If you need more details, you can get it at KB314056.
To see which svchost is associated with which single or multiple Service, right-click on the svchost.exe and select Go to Service(s).
In the Services tab, you will now be able to see the associated services, highlighted.
This tool gives you some basic information like the name and description of the services with a particular svchost process. It gives you information like:
- Process ID
- Amount of data written or read
- Name of Service, Service type, Start mode, Status
- Whether the service has the ability to be paused or stopped
- Brief description of the Service.
It also lets you stop or pause select services where possible and even lets you access the Service Manager directly.
If you want to reduce the instances of svchost processes, the only way to do it is by reducing the services which start-up automatically. If you want to disable services you may want to check out our Windows Services Tweaker. But I advice that you do so only of you know what you are doing.
