Svchost hogging yer cpu

less than 1 minute read

In case you’re using Windows (or Microsoft) Update, you’ll probably have noticed that your PC sometimes grinds to a halt after bootup. Checking with task manager usually reveals that svchost.exe is abusing your CPU, pegging it at 100%.

This thread specifies several solutions that you can try, and for me what helped was:

  • installing KB927891
  • installing Windows Update Agent 3.0 (x86 / x64)
  • cleaning of the SoftwareDistribution folder:
    1. Open a command prompt
    2. net stop wuauserv
    3. Rename Windows\SoftwareDistribution folder to SoftwareDistribution.old
    4. net start wuauserv
    5. Reboot

Doing the combination of these fixes (in this order) finally made svchost behave like it should. Look in the thread for more possible fixes ;)
