Windows 10: Monitoring svchost.exe Sub Processes

Good day,I have a very interesting issue. Whenever I lock my screen Windows 11, the fan starts to spin permanently. Not at the highest speed I assume, but actually higher than while I am working on the computer.Trying to troubleshoot it, I figured that svchost.exe was consuming 10-15% CPU while the screen is locked. As soon as I unlock it, it stops immediately. I then did some tracing of CPU load vs. Temperature while locked, and the long flat lines below are the time the computer was locked. The temperature will be steady at 90C, the CPU at about 13%:Now I have spent hours and hours, if no

Analyzing Svchost processes in Windows

Here's how to track down detailed information about any Svchost.exe process running in Windows 7/8.

a) You can use the Tasklist command-line tool to learn which services are running in a Svchost.exe. Just run cmd (command prompt) and hit

Tasklist /svc /fo list

Scroll through the list and find what you need. It's not quite intuitive so you can use third party programs with gui. See below:

b) You can use svchost viewer. Best utility. Note: to run this under XP you need .Net framework 2.0





c) Svchost Process Analyzer is another app for that.





d) And another app called Svchost lookup tool





e) And it won't hurt if you use Process Explorer and System Explorer.


It's never bad to keep your system under control, plus all these apps are portable no installation is required.

What does the svchost do?

Lots of Windows services are tied to the SVChost, and /or are listed as SVChost in the process list(s).

Unfortunatley with Vista, there's a lot more dependencies between the services, and thus you'll be FORCED to run more instances of SVChosts; unlike XP where things were more independent and you could disable more features resulting in less SVChost instances. That and XP and Vista are different.

Regardless of your Windows version, you can check out some service slimming guides or goto Black Viper's website and take his advice. Depending on your needs you may be able to cut down the amount of SVChost running, and save some RAM.

XP should never have an SVChost using 50mb. Vista however can.
