Resolving WinMgmt Errors Relating to Performance Counters (259796)

RESOLUTION

There are files named PerfStringBackup_xxx.ini (where xxx is a decimal number) in the System32 folder. A file of this type is created every time you install an extensible performance counter. These files are snapshots of the performance counter registry entries that are taken before you install a program's counters.

If you believe that your performance counter registry entries are corrupted, follow these steps:

1. List the PerfStringBackup_xxx.ini files sorted by name. You can use this list as a chronological history of the counters that have been added.
2. If there is an abrupt change in file size (for example, from 300 KB to 10 KB), the last file before the abrupt change in size is probably the last good file. It is likely that whatever was installed after that is responsible for the registry corruption. You can restore the registry to the last known good state by running the following command. Note, however, that doing so removes the performance counter references from all of the programs and services that were installed after this snapshot was taken.
   
   To restore the performance counter registry entries to the state described in a PerfStringBackup_xxx.ini file, run the following command

   lodctr /r:filename

   where filename is the name of the PerfStringBackup_xxx.ini file you want to restore.
