svchost.exe using 50% CPU

I had a similar problem with a processor running hot, right after an update.

I re-imaged my computer and all was well. Today I installed one update KB3161949 and the processor began running hot. Checked "svchost.exe" and as stated here one of them was running at 50%. Uninstalled the update, rebooted and everything is normal. Windows update is off.

Whats going on?

Open Task Manager. Under the Performance tab click Resource Monitor. In the upper pane look for the process that is using CPU, in your case svchost. Click on it and in the lower pane you will see the service that is using CPU resources. This will probably be your Windows Update Service. This has been a running problem with Windows 7 for the last few months. Windows update service runs and cannot obtain updates. If you manually check for updates it will run forever without being offered any. 

It has been found that you need to manually download and install one KB security update before Windows will offer any additional updates. See the below page on which updates to manually install. For the month of June the update to download was KB3161664. It also helps to have the latest update agent as explained on the page.

Also see this thread page. Holds true for both Vista and 7

I am closing this topic, since it has devolved into what should have been several different topics involving several different OPs.

In the future...please...initiate your own topic, regardless of how similar or otherwise connected it may seem to any topic initiated by another member.

Thank you.
