After installing Service Pack 1 you might find the following error in the event viewer:
Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60
WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage
> 99" could not be reactivated in namespace "//./root/CIMV2" because of
error 0x80041003. Events cannot be delivered through this filter until the
problem is corrected.
Here is the fix. Open a command prompt as an admin and enter the following pressing the enter key after each line:
net stop winmgmt
DEL C:\Windows\System32\wbem\Repository\*.*
Now reboot and let the system idle for a few minutes. There will be a couple of WMI warnings in the event log, but thats alright for the moment. Reboot one more time and the error and warning will be resolved.
