On my Windows 7 computer, I had noticed that one of the four CPUs was running around 100%, spending ±25% of my PCs CPU. As the number was slightly changing, I knew that it was not an infinite loop, so I started investigating.
Using standard Windows task manager, I saw that the process which was doing this, was a "svchost.exe" process. Following its process ID (PID) to the "Services" tab, I could derive that the "netsvcs" Windows service group was responsible. In order to know which of the subscribed services was responsible, I started up "Process Explorer" (a third-party extended task manager), which led me to the "wuauServ" Windows service. I have stopped it and the CPU dropped immediately, so I've found the service, causing the issue.
Now I would like to go further: the Windows Update service (wuauServ) seems to have problems (hence the high CPU), but nothing seems to be written to the event log (at least not to the "Windows Logs/Application" event log).
Does anybody know how I can find out what is causing the high CPU load of the Windows Update Service?
Thanks in advance
