In this short post I want to share with you how to find quicly what cause your CPU spikes.
If you hear your CPU's fan loudly, it's a sign of High CPU usage. Usualy we open Windows Task manger to see which process is causing CPU spikes, but when the culprit process is svchost you are not too advanced!
Svchost.exe is a process that hosts windows services and the Task Manager doesn't give you the possibility to know which service is running inside svchost.exe process !
You have to use instead Process Explorer instead.
In this Example svchost.exe is using 21% of my CPU. To have more details, I just clicked on the Process name and get this Windows.
The "Thread" panel shows the thread running in this process; in this case the Thread named "wuauserv" is responsible of my CPU spike.
So what is wuauserv? to get more information about this Thread I've clicked on the "Module" Button which showed me the following Window;
It become obvious that the culprit causing CPU spikes is the Windows Update service.
So, using the right tools can quicly helps you understand what's happening in your system.
