Dan - My OS is XP Pro. When I boot-up, the startups load and then one copy of SVCHOST.exe begins to hog the CPU until it takes 100% and the computer cannot be used. If I end the process, it fixes the problem until I boot-up again. I have the McAfee suite of antivirus and firewall applications. I have scanned the computer for viruses with none found. Any suggestions?

Thanks,
Russ

im having the same probs - my internet goes off after 5\10 mins with tht genric host problem

that microsoft link doesnt work with me i dont know why... pls help (mobali70@hotmail.com) pls help needed...
send me a link or sumtin pls - thanks to all \ for ur help!!

Thanks Dominic and Marek. I had the exact problem Dom. had. I re-installed win.xp twice and same problem. Went to the link Marek posted, downloaded the patch and have been surfing for the past two hours with no problems. Very grateful. Almost bought a new computer last night becasue of this problem. Joe. Student at UTEP.

I was experiencing 100% CPU usage while attempting to use Windows Update with a fresh install of Windows XP Professional off of an older MSDN CD.

Dan's solution (manually install the update located at http://www.microsoft.com/technet/security/Bulletin/MS06-040.mspx) was what worked for me. It took long enough to find it!!!

Thanks, Dan!

Erk. I'm an idiot.

That link was what Marek posted. Dan's suggestion (to shut off Windows Updates) made the computer boot without 100% CPU usage but did not resolve the issue when visiting Windows Updates.

So, thanks, Dan AND Marek!

I have a problem when booting my computer. The first time it happened, i got lucky by deleting one of the svchost.exe process using task manager. after that, my computer loaded, but then it started the one minute countdown, because 'rpc was terminated unexpectedy'.

So i went in safe mode, and it booted fine! i followed bv's steps on stopping the countdown, and tried to boot regularly. Same problem, only if i erase the svchost, the computer boots and doesnt start the countdown. (i know which one to erase because its always the second to last one towards bottom)

what do i do? i tried last known good config, and it worked once, then the problem started again.

i can't imagine how to fix this, becuase at the same time, my internet is not working. that may be a good thing, since i cant be hacked or infected by anything else, however now i cant update norton or use windows update.

also, about a week ago i had to use system recovery, because of another problem( in which it got to the background, and then logged out immediately).

os is windows xp home edition, so i cant use tasklist....and i cant download any substitutes because internet is down.

Well i have a diffrnt solution to the NEW bug which has been going around.

well the solutions are well either one - i applied the 2nd theory to use

1 = Turn on the windows firewall (Sp2) - it had to so something with the ports or sumtin or the other - but this should work

2 = my way - i went to my temp folder and deleted everything and my system returned to normal - no freezing internet\sound card dupes - goodluck everyone :)

My laptop kept freezing for about 5 minutes after bootup with SVCHOST.EXE utilizing 99% CPU. Completely turning off Windows Update fixed this problem, see this article http://searchwinit.techtarget.com/originalContent/0,289142,sid1_gci1207419,00.html which mentions a bug with Windows update affecting older/slower systems.

Turn off Windows Update. That's it :)

This procedure worked well. I used AVG and Zone alarm along with the updates. It worked well. I found that if I hit ctrl-alt-delete as the computer came up I could see if svchost.exe was dominating the process time. If I waited too long though I could not get ctrl-alt-del to work. It also gave me the ablility to kill the process in order to shut the computer down naturally without using the 10 second off button. My computer is running great. I appreciate you taking the time to post this article. You saved me a lot of time. Thanks, Tom
