I am running a Dell 3000 which I re-fomatted with sp3 for my cousin which was infected.  I deleted the partition and installed a fresh copy of xp.  I have been trying to do the Windows updates and the application hangs.  I go to task mgr>processes and it shows the 100% usage on svchost.exe.  I have ended it 5 times and it keeps coming back. I ran process explorer and it shows process id 3200- generic host process for windows 32 services.

I think windows update is the problem but am not sure.  I would appreciate any suggestions

For now just stop the service and restart the machine. Did that do anything?

I think its cos some part of the update service or related is stuck at starting (but not starting) causing it to hang and hence the high cpu.

Now lets try this:

Open a command prompt: Start | Run | cmd /Enter

del /f /s /q %windir%\SoftwareDistribution\*.* – ENTER

net start “Automatic Updates” – ENTER

wuauclt.exe /detectnow – ENTER

the second line I get error...I copied/pasted your command for - net start “Automatic Updates”  the service name is invalid

 

Is it because I have auto update turned off?

Hmm. That just turns on the service which you can do in security center

The last one forces a check for updates

Hi. I'm new here so I hope that my post doesn't upset any protocols. I opened this thread because I too have a frozen desktop but I should have opened this one, showing it's all down to a Microsoft foul-up (I'm being polite).

 

http://www.bleepingcomputer.com/forums/t/514140/svchostexe-using-100-cpu/

 

Does this help you?

 

I hope that I typed in the link correctly - I couldn't paste it.

I appreciate all the help.  I have found that windows update was the culprit.  Animal, How do I know which services are ok to stop if they are the cpu hog? ex-dcom...what is it?

ex-dcom...what is it?

 

I think its a system service linked to Microsoft Security Essentials,but also other things,might be better not to disable.
