Fixing WMI Corruption on Windows 7

We had a workstation that wasn’t getting updates properly. Here are some items in the logs we noticed:

Event ID 43:
Windows Management Instrumentation ADAP failed to connect to namespace \\.\root\cimv2
 with the following error 0x80041002


Event ID 1090:
Windows failed to record Resultant Set of Policy (RSoP) information, which describes the scope
of Group Policy objects applied to the computer or user. This could be caused by Windows
Management Instrumentation (WMI) service being disabled, stopped, or other WMI errors.
Group Policy settings successfully applied to the computer or user; however, management 
tools may not report accurately.

Use the winmgmt command to see if you have WMI corruption:

C:\Windows\system32>winmgmt /verifyrepository
WMI repository is INCONSISTENT


Shut down the Windows Management Instrumentation and any dependencies, or you will get this error:

C:\Windows\system32>winmgmt /salvagerepository
WMI repository salvage failed
Error code:     0x8007041B
Facility:       Win32
Description:    A stop control has been sent to a service that other running ser
vices are dependent on.


Fix and verify:

C:\Windows\system32>winmgmt /salvagerepository
WMI repository has been salvaged

C:\Windows\system32>winmgmt /verifyrepository
WMI repository is consistent


Run gpupdate:
