Stop Event ID 10 WMI Application Log Errors After Installing Windows 7 SP1

If you install Windows 7 Service Pack 1 (SP1) using a standard installation DVD, you may start seeing a new WMI error in the Application log after every restart.

I confess to being something of an Event Log tidiness freak – despite the fact that such errors are rarely serious (and sometimes insoluble without uninstalling the ‘faulty’ application) I hate to see them clutter up the logs.

Too many insignificant errors can make it harder to see the wood from the trees and spot an error which is actually serious so I usually try to prevent them from happening in future – and this one is no exception.

The error appears in the Application log with a Source of WMI and an Event ID of 10 – the General tab for the error specifies the following, rather daunting, details:

“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”.

To check if you have this error – open the Computer Management window (press Start then right click ‘Computer’ and select ‘Manage’).

Navigate down to Event Viewer \ Windows Logs \ Application. You could scroll through the log to find the error but a quicker way is to just click on the Event ID column heading to sort by ID and look for ID 10 errors – alternatively, click on ‘Filter current log’ in the Actions right hand panel and tick the Event Level of ‘Error’ then press OK to filter the log to display errors only.

This particular error is not serious – although the long description makes it seem dramatic, it originated in the Windows 7 SP1 DVD/ISO creation process – per Microsoft, it can be safely ignored and does not mean that there is any issue with Windows.

However, there is a Microsoft Fixit available if you want to stop the error from appearing in future. Visit the Microsoft Support page here and download the Fixit then run it – after it completes, you should not see this particular error appear in the Application log ever again.


There is strictly no need to run the Fixit as this WMI error is unimportant and is not a sign of any genuine problem with your installation of Windows 7 SP1. However, if you want to keep your event logs clean and tidy in future, it’s worth taking a minute to eradicate it from your system.
