Windows Update Client

popped up as a threat on windows security essentials.
   
If they had half a brain the file would only startup when the updates were scheduled instead of wasting resources all day every day.
   
I kept getting an 'update' popup (midscreen) saying it needed .NET framwork. I installed ".NET framwork v2" and it seemed to 'fix' the popup for Update and the cpu isn't running at 100% all the time now.

Do not disable this service! Run your Windows System File Checker (SFC) to detect for any problems with the file - it'll replace it if needed.

It is a windows automatic updater but you need to disable it and update manually. You need to make sure is the right package before dowloading the update. I didn't do it in one of my computers and it downloaded a trojan with the same file name and extension. So, disable your auto-update and do it manually from now on.

Windows update - It runs for hardware driver searches even when all windows update processes are turned off. On principal I want to disable it on any well tuned system.
