Specifically a series of commands detailed at labeled Remove and Reinstall of Automatic Updates seems to resolve the issue for many people. As we’ll see shortly, this will also become important to resolve this problem “for real”.įolks commenting on a previous svchost article have reported success by removing and reinstalling Windows Update.
RUNDLL32 EXE 99 UPDATE
IMPORTANT: since you won’t be getting updates automatically, you should now plan on visiting the Windows Update web site periodically to make sure you keep your Windows up to date. (You can also click Stop here if you didn’t stop the service earlier.)Ĭlick OK and Automatic Update service should be disabled. Right click on Automatic Updates and click on Properties. In the resulting list on the right, locate Automatic Updates: Expand Services and Applications, and then underneath that click on Services. To prevent the Automatic Update service from starting again, right click on My Computer and click on Manage. If your CPU usage then drops to more normal levels, you’ve identified the problem.

If you have it open in Process Explorer, as shown above, with Automatic Updates selected in the list, then just click the Stop button. One approach to this problem is to stop and then disable the Windows Automatic Update service. So if you were to kill this instance of svchost you’d be killing all of those services and many features and functionality of your system would fail. You can see that this copy of svchost on my machine is running not only The Windows Update service, but is actually running 29 services all totaled. The bug appears to be related to the Windows Update service – the service that you’re supposed to keep running at all times so that updates will be automatically downloaded to your machine.Ī quick way to tell if this is happening to you is to download Process Explorer and right click on the svchost instance that’s taking 100% of your CPU and then click on the Services tab: A serious and annoying bug, but a bug nonetheless. So why is one of the Svchosts taking all your CPU?įrom what I’ve heard and have been able to tell, this is nothing more than a bug.

Svchost, or more correctly “Service Host”, is a program that is designed to run other programs and “hosts” many of the system services in Windows XP. Several copies of Svchost run more than one service, which is why when you kill an instance of svchost several things on your machine might stop working. You’ll often find several copies of svchost running. In fact it’s a required system component. That’s actually a composite question based on several reports I’ve been getting recently.
