Rebuild the WMI Repository

Reading Time: < 1 minute

If your Windows device is having issues reading from the Windows Management Interface (WMI) repository, you may need to re-sync the repository as a troubleshooting step. To perform a repair/re-sync of the WMI repository, please do the following:

For Windows XP and Windows 2000 Servers:

winmgmt /clearadap
winmgmt /kill
winmgmt /unregserver
winmgmt /regserver
winmgmt /resyncperf

For Windows 2003 Servers:

wmiadap.exe /c
wmiadap.exe /f
lodctr /R

For Windows 7 and Windows 2008 Servers:

winmgmt /salvagerepository

To perform a repair/re-sync of the Windows 10 WMI repository:

  1. Open an elevated command prompt.
  2. Verify the WMI repository is not corrupt by running the following command:
winmgmt /verifyrepository

If the repository is not corrupted, a “WMI Repository is consistent” message will be returned; if you get something else, go to step 3, otherwise if the repository is consistent, more troubleshooting will be required as the repository is not likely the problem.

  1. Run the following commands to repair WMI:
winmgmt /salvagerepository

If the repository salvage fails to work, then run the following command to see if it resolves the issue:

winmgmt /resetrepository

After the last command, there should be a “WMI Repository has been reset” message returned that verifies the command was successful.

To perform a rebuild of the WMI repository, please do the following:

  1. Disable and stop the winmgmt service
  2. Remove or rename C:\Windows\System32\wbem\repository
  3. Enable and start the winmgmt service
  4. Open Command Prompt as Administrator
  5. Run the following commands:
cd C:\Windows\System32\wbem\
for /f %s in ('dir /b *.mof') do mofcomp %s
NOTE: This will take a minute or so to complete.
for /f %s in ('dir /b en-us\*.mfl') do mofcomp en-us\%s

Open Performance Monitor to verify that all counters can be loaded.
