Fix For svchost.exe Using 99% CPU Usage

[ConfederateTyrant]

Hello everyone, this has been a major problem at my work lately. Some kind of Windows Update (I only saw it happen with Microsoft Updates) caused some corruption which makes svchost.exe use 99% of the CPU usage for a long time before it calms down. svchost.exe runs at extended usage when Windows/Automatic Updates happen, and if it is corrupt, then it will hang there. This will happen everytime the computer loads up, comes out of standby, and periodically throughout the day when it checks for updates. Here is a fix, which has been mostly successful on all the computers coming in at work.

Instructions:
Go into Safe Mode
Go to Start -> Run.
Type in services.msc
Verify that "Automatic Updates" and "Background Intelligent..." are Automatic.

Go to Start -> Run and type in the following, one at a time:
REGSVR32 WUCLTUI.DLL
REGSVR32 WUWEB.DLL
REGSVR32 WUPS2.DLL
REGSVR32 WUPS.DLL
REGSVR32 ATL.DLL
REGSVR32 WUAUENG1.DLL
REGSVR32 WUAUENG.DLL
REGSVR32 WUAPI.DLL

Go to the Windows folder.
Delete the Software Distribution folder.

Reboot and verify through Task Manager that svchost.exe is not using 99% of the resources for an extended period (longer than 30 seconds) of time. Then manually do Windows Updates and verify the same thing.

If anyone has any questions, let me know.

Thanks for the fix! MS just released a fix for this issue.

Although, I like the best fix is just to install SuSE Linux

Microsoft's fix failed to fix a couple of computers, or so I was told by a co-worker. He said that the manual instructions I posted worked though...
