wuauclt.exe and svchost.exe - enormous CPU/memory usage RRS feed

  • Question

  • Windows Update appears to be woefully inefficient on CPU and RAM in Windows XP, I see there was an update to fix this for XP2. Is there another one for SP3 because I assume this fix was included in SP3 considering it was such an issue.

    Thanks in advance.

  • Think you will see this as a MS feature :)

    Have you run Process explorer then looked at the threads to find the exact culprit?

  • Use the Sysinternals Autoruns (http://technet.microsoft.com/en-us/sysinternals/bb963902) and Process Explorer (http://technet.microsoft.com/en-us/sysinternals/bb896653) tools to find all the programs loaded at the system startup and the services executed inside each svchost.exe instance: then you can decide which ones are necessary and which ones can be disabled or removed.
    Talking about wuauclt.exe, you could configure Windows Update to not check automatically for new udpates.
