    Windows gives the following error in the event log:

    The performance strings in the Performance registry value is corrupted when process %1!s! extension counter provider. The BaseIndex value from the Performance registry is the first DWORD in the Data section, LastCounter value is the second DWORD in the Data section, and LastHelp value is the third DWORD in the Data section.

    Event Source: Microsoft-Windows-LoadPerf
    Event ID: 3012

    This is caused by either the performance counters being corrupt or a permissions error. To fix the corrupted performance counters, run the following command in a command prompt that has been run as administrator (right click the command prompt icon and click Run as Administrator):

    lodctr /r

    You will then get the following message and you shouldn’t see error 3012 in your event log anymore:

    Info: Successfully rebuilt performance counter setting from system backup store
