Windows 2012 R2
SQL 2012 Enterprise
Windows Vista Business 32 Bit
On my Windows Vista Laptop which is domain joined all of a sudden I am getting 100 % CPU all the time
After researching I found the when I stop BITS and WUAUSERV services my CPU drops to nothing.
So I did a tasklist /svc /fi "imagename eq svchost.exe and found wuauserv the fending service
I then went to the registry key
HKLM\SYSTEM\CSS\Services\WUAUSERV and changed the value from 0x20 to 0x10 but that did not help either
Then I rebuilt the Computer and put Windows 7 on it with the same results.
Then I put back on Windows Vista Business and applied all the updates via WSUS server
All was good even after Service Pack 2 was installed for Vista.
Then I found the problem
This update applied
Windows Update Agent version 7.6.7000.256
This was installed automatically I cant seem to uninstall it.
This is what is causing the high cpu and now the computer will not report to my WSUS server
This is a 32 bit Laptop and I believe only 1 core on the CPU very low end.
But this has been working for years with no issues
Windows Update Agent version 7.6.7000.256 is the problem I know for sure
I tested this theory by doing a System Restore on the Vista computer and then the cpu went back to zero.
If I stop the services it goes back to zero
But then the policy triggers the service again every 6 hours to check for updates from wsus server and that when the cpu spikes to 100%
Can I stop the Windows Update Agent from updating?
Is there a patch or update I might be missing?
Any ideas on this
