When svchost may occupy 100% cpu usage… THE CURE
When svchost process may occupy 100% cpu usage.
To cure the situation,
1) identify the greedy process by “process explorer”. http://www.microsoft.com/technet/sysinternals/utilities/ProcessExplorer.mspx
2) Greedy errorsome process may be the wuauctl.exe, windows autoupdate (WU)program. Microsoft Updater (MU) is not in consistence with previous WU.
3) Delete the file in the folder, C:\WINDOWS\SoftwareDistribution\DataStore or delete the folder itself, Microsoft MPV said. The folder may be not deleted for its currently usage.
Today it seems that the problem is solved by MS. However I write this post for whom need solution for XP cpu 100% usage problem. Anyway, “Process Explorer” is useful for diagonostic.
