Repair Corrupt WMI Services

Repairing and re-registering the WMI Services

Rebuilding the WMI Repository

If you experience behavior when using WMI, such as application errors or scripts that used to work are no longer working, you may have a corrupted WMI repository. To fix a corrupted WMI repository, you have to reinstall WMI. Follow these steps:

• Click Start, Run and type CMD
• Type this command and press Enter:

net stop winmgmt

• Using Windows Explorer, navigate to %systemroot%\system32\wbem directory and delete the Repository directory. By default, the repository folder is located in the C:\Windows\system32\wbem directory.
• Switch to Command Prompt window, and type:

net start winmgmt 

Re-registering the WMI components

The .DLL and .EXE files used by WMI are located in %windir%\system32\wbem. You might need to re-register all the .DLL and .EXE files in this directory. If you are running a 64-bit system you might also need to check for .DLLs and .EXE files in %windir%\sysWOW64\wbem.
To re-register the WMI components, run the following commands at the command prompt:


cd /d %windir%\system32\wbem
for %i in (*.dll) do RegSvr32 -s %i
for %i in (*.exe) do %i /RegServer
