So my PC was acting very slow, and I went to task manager and saw one of the svchost processes taking up 95% of my CPU!

Well, I needed my computer so I killed that process and my PC immediately took off.

The draw back is I lost all sound.

I am assuming there was some audio component loading/trying to load and killing that process stopped all audio on my PC.

Is there a way to track what invoked svchost and caused my slow down?

Oh sorry.

Open a dos prompt and type TASKLIST /SVC

This will show you which services have made calls to svchost.

Compare the PID from task manager with the PID from TASKLIST and you get a list of possible services.
