Hi this problem is a mix of 2 problems, one a virus, but more likely a problem with windown auto update, which you should uninstall/reinstall. Apart from that but ErrorSmart for about 20 USD run it to fix registry problems, and if that doesnt work, sign on for their online tech chat, and they are very good, using a number of other apps like SmitFraudFix, ComboFix, it fixed my problem after a few hours. BTW this product is better than regcure.

This is my First Post. I had the same issue as SVCHOST 100% utilization issue. After tried, downloaded the patch (WindowsXP-KB927891-v3-x86-ENU) it doesn't solve the issue.
After reading most of the threads I found most of the issue appears when they tries to access internet, so I just did
>> Right click on connection which I am using (Wireless Network Connection)
>> Repair.
It automatically solved my issue and my system is now working fine
SVCHOST.exe (Services Host) is a front end service, each instance controlling functions such as copy and past, open link in new window and so on .. there will be several instances of services host running on any NT based system, in the case of both XP and Vista where this service tops out CPU usage please download support.microsoft.com/kb/927891 from Microsoft or disable automatic updates, either will fix the problem. the thread priority as mentioned in other replies cannot be controlled and it should never be removed from the start up list!
Don't disable it!
An application is at fault.
This is is process which runs dlls as applications. You will have a horrible time if you disable this! A dll is basically a code bucket and svchost is using it to run many system things. What other applications are opened? What other services are using a lot of CPU time?
Never just go disabling processes. Try blackviper.com to slim your processes (a good list) (this is not a plug, wait it is).

Please re-read my post, I stated you "Can" disable automatic updates .. but you "Cannot" disable episodes of services host!!!... me thinks you got confused.
Yes, you're completely right that you could disable them. It's probably not the right move, but you can. (oh I see, I was talking about the svchost svc!) reassurance helps sometimes.
If you start up in safe-mode does the problem still occur? If so then not the differences in launched services and de-activate and check in normal boot mode using the half-cut method.
EX:
Re-enable half. Is it fixed still? Yes, re-enable half of the other half, did that break it? Yes, you can now narrow it down more, take half of those and enable them, did it break? Yes, take half... Etc
Find the service at fault then post back.
