    Hello

    Thank you for posting in Microsoft Community forum.

    This issue occurs when the counters cache in the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009\Counter+Help becomes corrupted (has blank lines).

    You can try rebuilding the cache by running lodctr /r from an elevated command prompt. If you get an error when running this command, you may need to run it from the C:\Windows\SysWOW64 directory instead.

    If this does not resolve the issue, you may need to check the event log for Event ID 3006 and change the Disable Performance Counters value from 1 to 0 in the registry.

    Best Regards,

    Wesley Li
