Hi

HELLP!!

This is a problem I have been having for about 8 mos & it seems to be getting worse. Occasionally (& more often depending on how much & many Windows Explorer type tasks I'm doing) CPU cycles will will shoot thru the roof.

I read something somewhere about a Widows update having to do with svchost. In fact there were 2, 3 or 4 of them, each trying to fix the same high cpu cycles thing having to do with the explorer process, but not entirely helping. But I cannot find it now.

I am running Windows XP Pro on an AMD box. All updates. AV is AVG Free. Firewall is Comodo Pro free. Also Ad-Aware, Spybot, Spyware Blaster. Also Robin Keir's freeware & Sysinternals freeware. Firefox is my primary browser.

Any help would be very much appreciated. Thanks.

Download Dimio's DTaskManager and see if you can identify which programs each schost go to.
Post the results here for review.

Thank you, acklan for your reply.

I have Process Explorer installed with which I am very familiar. But I am not absolutely sure what you mean by "which programs each go to".

I'll surmise that you mean the command line and/or the services registered for each (I have 3 svchost processes currently running). They are:

(1) command line = x*:\WINDOWS\system32\svchost -k rpcss
services = x*:\WINDOWS\system32\rpcss.dll

(2) command line = x*:\WINDOWS\System32\svchost.exe -k netsvcs
services = about 25 of them on this instance of the process

(3) command line = x*:\WINDOWS\System32\svchost.exe -k imgsvc
services = x*:\WINDOWS\system32\wiaservc.dll

* obscures actual drive letter (which in all cases is the same system drive)

Sorry, if this is not what your looking for. Will try to provide if you can clarify.

Hope your on to something here, acklan. I had a much longer post originally but changed it. Maybe it will clarify (or confuse), if you want to see it).

Thanks, again.

BTW, DTaskManager looks interesting & I may try it. Especially if it can better provide the info you need.

Try TEMPORARILY disabling Windows Updates and see if that fixes the problem. If it does, let us know and we'll check for the workaround that's been published.

Thanks, usasma, but for me, Windows Updates done manually is & has been for a long time the only way to go.

I was referring to the folder that the scvhost are in. Virus use names of legit fill to hide their real nature.
I do not see any thing out the ordinary. The "x*:\WINDOWS\system32\wiaservc.dll" is part of Window's Windows Image Acquisition (WIA) and is necessary.
The "x*:\WINDOWS\system32\rpcss.dll" is also part of Microsoft Remote Procedure Call (RPC). It too is necessary.
If you list the other 25 entries we could go over them.

OK. But will have to leave that for tomorrow. Will have to open up an account on an image sharing site somewhere as, like I said, there 25 of them & I hate typing. Unless I can just upload a picture right from my PC. But don't see an option for that. I'll be back.

Are you notified of updates being available by Windows? If so, then the Windows Update service is still running. If you have to manually surf to Windows Update to check for updates, then it's shut off.

If you only have 3 instances of svchost.exe running, there's likely to be somthing missing. I've got 5 of them in my brand new XP install. What are the User Names for each svchost.exe process (I've got 2 Network Service, 2 System, and 1 Local Service)
