We have found two issues that occur within Microsoft Windows that affect our family of System Mechanic products from properly starting. 

Primary, is a Windows Update that has corrupted Windows Management Instrumentation (WMI), via Windows .Net Framework. Second, a WMI namespace gets unregistered during a Windows Update and needs to be reregistered. 


STEP 1: Verify Windows WMI Related


The best way to start out verifying if this is WMI related is by simply going to the Windows Search, or command-line prompt, typing msinfo32, and clicking Enter. When the application window appears, if the window pane shows that it could not load, it is in fact a Windows (WMI) issue.


STEP 2: Verify Windows WMI Service Status


Navigate to Windows Services and check to make sure the Windows Management and Instrumentation Service is started.

If it is not, try to start it. If the service cannot start, none of the troubleshooting in this article will help and the customer will inevitably need to run a repair of Windows. If it is started proceed to step 2.


STEP 3: Repository Status and Repair

Check the consistency of the Windows repository and perform a salvage or repair if necessary.  

Note: These commands must be run in the command console as Administrator

verify respository
"C:\windows\system32\wbem\winmgmt.exe" /verifyrepository

If inconsistent run the following commands verifying each time:

rebuild repository
"C:\windows\system32\wbem\winmgmt.exe" /salvagerepository

reset repository
"C:\windows\system32\wbem\winmgmt.exe" /resetrepository

STEP 4: Verify the root\default WMI namespace

Navigate to the Windows Control Panel > Administrative Tools > Computer Management > Services and Applications. Right click on WMI Control > Properties > Advanced tab.

Normally a default namespace will be shown. If not, register the namespace with the following command:

"C:\windows\system32\wbem\mofcomp.exe” CimWin32.mof


If none of the above works, run a repair with a Windows install disk. Operating System images are normally available on Microsoft’s website.
