SVCHost.exe for WUAUServ takes up 100% CPU on XP SP3

Hi Expert-Exchange,

We have a computer that is having performance issues due to a SVCHost.exe for just the WUAUServ using up all available CPU processing.

We checked the updates in this article but they had already been installed.

Also tried the fix here and it did not resolve the issue
That was setting the Updates to just do Windows Update instead of Microsoft Update and recreating the Data Store.

Thanks for the help,

You may have malware running on that computer.  I would recommend running a utility like  Malwarebytes Anti Rootkit and see what it finds.
This is a known issue which does not have a permanent solution yet.

Microsoft never proivded a solid solution for this issue.

However there isa workaround.

The problem is not with SVCHost.exe ( "Service Host") but with the program it try to run:WUAUServ( Windows Automatic Update service).

The workaround is to go to computer management /Services and disable Automatic Updates) and disable the serivce and then ask user to get the latest updates from the windows update icon on the start menu.
