Re: svchost.exe 100% cpu usage pissing me off :(
 

For those of you who have svchost.exe using 100% CPU, I used to be one of you. I found out what the problem was. The first thing I did was download Process Explorer from here: http://www.microsoft.com/technet/sys...sExplorer.mspx It look up svchost.exe and found out wuauclt.exe (Automatic Updates) was consuming most of the CPU. After realizing that Automatic Update was the source of all the trouble, I went to Control Panel > Security Center, then I scroll down to find Manage security settings for: then click Automatic Updates. Finally click Turn off Automatic Updates then OK and my trouble was gone. My CPU usage drop the second I disable Automatic Updates and my computer was fast and usable again. You should try this, it work for me and maybe for you!

Hi, I had this problem also and I think I found the fix on another site. It seems to work for me. It is an issue with Auto Update.

Go here and look down the page for a post from pati610.

Hi

I have had this problem on a couple of machines.

The following worked on both occasions.

Right click on my computer- expand Services and applications – click on services – Right click on automatic updates – Properties – select disabled as the startup type. Reboot , navigate to C:\windows\ rename the folder SoftwareDistribution to SoftwareDistribution.old
Go back to services and set the startup type to automatic.
Reboot – failed updates should now install and CPU usage drop to normal level.

Hi,

I tried this fix and cannot rename the folder, due to an access denied message. I tried by right clicking and selecting rename. I also tried changing the attributes to eliminate the read only. Why doesn't it work?

Re: svchost.exe 100% cpu usage pissing me off :(
 

Hi, the folder cannot be renamed if it is in use. It is usually in use by the Autoupdate service that is why you have to temporarily disable this service and then reboot. Once the machine has restarted you will be able to rename the folder.

Remember to set the service back to start automatically when you are done.

Re: svchost.exe 100% cpu usage pissing me off :(
 

I'm an A+ certified PC Technician and have run into this problem countless times and seem to have started since the release of Microsoft Update. Microsoft Update combines both Windows and Office Updates together. The result is 100% CPU utilization for prolonged periods. If you're not doing anything and the CPU is 100% or you hear your CPU fan kick in like an airplane taxing down the runway at takeoff, chances are good that Automatic Update is checking for Windows/Office Updates. Microsoft has a "hotfix" that claims to fix this but it's not publicly available for download and prompts you to call Microsoft to get it. Well, I did call Microsoft and it was like pulling teeth to get it. The 3 different technicians I spoke to cite other local factors, like malware (virus, trojan horse, adware, spyware, etc) or other CPU intensive programs running at startup. With a little more force and less patience, I asked to skip the troubleshooting and go right to the hotfix. Surprisingly, none of the Microsoft technicians were able to get to it and kept transferring me to someone else in India (OK, OK, maybe it was Bangladesh) who gave me the same answer. After a lot of head scratching, I was finally E-mailed the "hotfix" but it was password protected, and only good for two weeks. So, basically useless for helping others out over a long period of time. To my surprise, the fix was actually a patch for the hotfix, so it did absolutely no good without having the original fix. I gave up trying to make Microsoft Update work. Here's the manual fix:

The first step may not apply if you don't have Microsoft Update installed:
Go to Windows Update.
On the left side, click the link "Change settings".
Check the box "Disable Microsoft Update software and let me use Windows Update only".
Click "Apply changes now".

Now, onto the slightly technical part:
Right click My Computer and click Manage.
Click the + next to Services and Applications.
Click Services.
Right click Automatic Update and choose Stop. Keep this window open, as you'll need to come back for the last step.
Open up Windows Explorer and browse to %WinDir%\SoftwareDistribution\DataStore. Note: %WinDir% is usually C:\Windows or C:\WinNT
Delete the contents of DataStore.
Lastly, go back to the Computer management window and right click Automatic Update and choose Start.
No reboots are necessary and I'd be very surprised if this doesn't fix the issue with SVCHost.exe running 100% CPU time.

Theory:
Using Process XP (a souped up Task Manager browsing Processes) shows that when CPU utilization is 100% that SVCHost.exe is married to @ 2 DOZEN different services. I can't think of any reason why one single process should have that much association with other services. Most processes link to at most 1/2 dozen services. It's no doubt that CPU's are busy with that much linked association. I truly hope Microsoft identifies and repairs the code to their Microsoft Update. I now have to remember to manually run Office Updates separately. Good luck to you all.

Re: svchost.exe 100% cpu usage pissing me off :(
 

I applied the patch listed above (which had a 5/7/2007 date on it). I turned automtatic updates back on and things seemed great for a few minutes (previously it took only about 2 minutes to lock up), but then 100% cpu usage for svchost again. So I'm back to no automatic updates and still looking for a permanent solution. Thanks so much for getting me on the right track with the automatic updates. At least I can use the machine!

Hello, I am posting this here because of this site's high google pagerank.

The workaround for this:

Disable windows update service by going to Control Panel > Administrative Tools > Services and stopping the “Automatic Updates” service. Set it to disabled for now.

This will stop the freezing issue.

The fix for the windows update svchost.exe error is this:
1. Install the new windows update client:
WindowsUpdateAgent30-x86.exe
http://download.windowsupdate.com/v7...gent30-x86.exe

2. Install hotfix KB927891
