In the  Application Log File I can see a WMI error code 10.
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.

This error has never caused any loss of functionality on this system that I know of, (I’d actually forgotten about it till I noticed again today), but it is kind of a point of honor for us admins to try to get rid of any and all true errors in the log files so to work I went!

It turns out this error is related to a permissions issue with Vista.  If, like me, you have a secondary, maybe limited profile setup on your machine then you are a prime candidate for the error.  That profile doesn’t have sufficient permission to the WMI filter. 

To rid yourself of it, goto: KB950375 and follow the instructions there.  But before you can run the script they give you (you’ll know because you get an Access Denied error when you execute the script), you’ll probably have to turn off UAC (User Account Control) first.  To do that, open up MSCONFIG and disable UAC via the Tools tab (highlight and click Launch).
After you run the kb950375 script, enable UAC again. It provides vital protection to Vista.

Note: If you get an error running the script that refers to:
“Access denied
Code: 80041003
Source: SWbemObjectEx” then you will want to logoff the current profile and logon with an administrator account to run the vb script.
