  2. Click the Windows Start button and type cmd, then right-click Command Prompt from the search results and select Run as administrator.
  3. On your keyboard, press the Win key and X key simultaneously, then select Command Prompt (Admin) from the menu that appears.
  4. Click the Windows Start button and select All Programs (or Programs) ▸ Accessories.
  5. Right-click Command Prompt, then select Run as administrator from the context menu.
  6. If prompted for permission by the User Account Control dialog, click Yes.
  7. Type winmgmt /verifyrepository into the Command Prompt window and press the Enter key on your keyboard to perform a consistency check of the WMI Repository.
If you receive the error message WMI repository verification failed... ...Access denied when running the above command, repeat steps 1. - 4. listed above.
