I had to call microsoft support. They ran tool to re-register all the DLLs using regserv. This solved the problem.

Getting updates via Windows Update site is now impossible.

However, I've found a site that will allow you to get your updates using Firefox browser and presumably other browers. I installed it and it works! (I used their tool vs. the regular install because I have no knowledge of how to install unsigned plug-ins)

www.windizupdate.com

I put Help Service and Windows Update service in their own svchost and this fixed things.
Now Windows Update starts up at boot and hardly consumes any resources at all, and periodically when it and Help Service come on they don't consume much resources any more.

I used the "sc config wuauserv type= own" and "sc config helpsvc type= own" commands

I am pretty sure the batch file called "Reset Automatic Updates System" on this webpage worked - http://www.amset.info/windows/auto-updates.asp#Reset-Automatic-Updates

I ran it yesterday, rebooted a couple of times and when Automatic Updates came on it only took 10-15% of CPU for very short periods of time.

This morning on reboot it still only took 10-15%

Hi,

Hi, Since yesterday my laptop is getting slow because of windows updates. I did net stop wuauserv the cpu bacame 0 % busy, a few minutes later it bacame again 100% busy and again wuauserv was binded to svchost taking 100% cpu. process monitor helped a lot identifying this.

The SOLUTION came up in some other forum:

http://www.microsoft.com/communities/newsgroups/en-us/default.aspx?dg=microsoft.public.windowsupdate&tid=fd41763e-33d0-4947-8cd8-1e1bfaae4183&p=1

And the solution to my laptop cpu 100% busy problem was to run the following script:

regsvr32 MSXML3.dll
regsvr32 WUAUENG1.dll
regsvr32 WUAPI.DLL
regsvr32 WUAUENG.DLL
regsvr32 WUAUENG1.DLL
regsvr32 ATL.DLL
regsvr32 WUCLTUI.DLL
regsvr32 WUPS.DLL
regsvr32 WUPS2.DLL
regsvr32 WUWEB.DLL
net stop WuAuServ
rename %windir%\SoftwareDistribution SoftwareDistribution_buggy
net start WuAuServ

By the way, I believe this script should be harmless to run...

Hope this may help everyone solving the same problem!

Cheers

My CPU operating 100% was due to low connectivity. Once I turned power off at source and replugged all the connections at the back of the tower including the blue pin plug with the two screws to ensure they were properly connected, my 100% CPU problem was solved

I set a recovery point every time I made a change to my system and was able to pinpoint where things went south with Svchost. It turned out that my HP printer utilities for my C7280 caused the SVCHOST/CPU issue. Process Explorer helped me identify and confirm this as it tuned out a HP DLL was caught in a loop. As this DLL only sniffs for IP address changes related to the HP device on my home network, and I had hard set the IP for that device, I could easily shut it down and set it to manual.

Problem solved for me. I guess that SP3 is not watertight for all different devices esp when these are relatively new.

I therefore strongly recommend using Process Explorer.

Good luck to all and thanks Leo!

FWIW: About two weeks back I had this problem with svchost hogging all my CPU for over four days (using WinXP Pro SP2). I tried all the suggested fixes I could find, even did a reinstall in place -- all to no avail. I was about ready to shoot my PC, when I tried simply disabling my "DNS Client" service. _Immediately_ the problem disappeared! That was a week ago, no fallout has occurred, and I'm still savoring the way my PC is running.

BTW, this is repeatable: if I restart the DNS Client service, svchost goes berserk; turn it off and the problem goes away.

My system has had the same problem from time to time. Recently, the culprit(s) this time was, Service Pack 3 update...It caused my USB Wireless Network Adapter to go down. At startup, I constantly received missing "AirPlusCFG.exe" and WZCSLDRZ.exe" alerts after the update (cheap way for Microsoft to do coexistence testing...all is forgiven). CPU usage remained at 100% and the system never settled down all night. After troubleshooting the next morning, I found and immediate fix on the device's, D-Link, Web site. Also, Microsoft's "Outlook Connector" will set my CPU over the edge. By the way, I have the same HP C7280 on my home network and HP DLL, or some other missing DLL, can definetly gobble up CPU resources and will/may not show up in Task Manager. I currently have 5 programs running and 58 processes with CPU usage ranging from 3-22%...10 of which are svchost...System is purring!! By the way Leo, I truly truly miss the North West!!

Hello about this issue regarding high cpu usage from svchost.exe i think i isolated the problem to microsoft update when a user has applications like Microsoft office this occurs when trying to update all software at once with "Microsoft Update" i had several issues with this problem as i work to aftermarket technical support . You can turn off Microsoft Update at the update site that Microsoft Update takes you to. Dont know if that helps in your case i corrected many windows installations in this way give it a try if you allready depleted other solutions
