scvhost.exe 100% CPU usage while running wuauclt.exe

***Updated 25/04/2007 See the comments for the latest on this issue (scroll down)*****

Apologies for the post title but it best describes the problem.

Back in Windows XP Tech Support World (or the Real World as you know it).

I spend some time today looking at the problem in Windows XP Pro. I had a laptop that when logged on scvhost.exe was taking 100% of the CPU for about 70 seconds.

Looking into what scvhost.exe was doing, in this case wuauclt.exe (basically windows update).

Turning off Automatic Updates made it go away but that’s not really a solution.

The link below was the most helpful in fixing this issue for those in the same boat.

Also helpful in dealing with rogue Windows processess is the Process Explorer from sysinternals > now Microsoft (Thanks to Mark Russinovich for a such great tool)

    Hi Lou

    This is the latest support link from Microsoft on this issue, it was updated today (25/04/2007), so may supercede some of the forum links below.

    If that doesnt work….

    As Microsoft have removed the original forum post but you can still find the content in google’s cache.

    The solution offered by “pati610″ seemed to work for some people.

    or This also helps.

    I followed the fix suggested by “The ToOTaLL” on page 4 of the above link. The wufix download.

    Thanks for leaving a comment.
