In Windows 2000, Windows XP and Windows Server 2003, if you wanted to rebuild the base O.S. performance counters you had to go thru:

In Windows Vista/Server 2008 and higher, a very easy command to get your base O.S. performance counters working:

Click on Start, CMD (evelated as an Administrator)
Type "C:" without the quotation marks and Enter.
Type "CD\windows\system32" without the quotation marks and Enter.
Type "LodCtr.exe /S:Backup_Original.INI" without the quotation marks and Enter.
Note: This let's you backup the performance counters before we rebuild.
Type "LodCtr.exe /R:PerfStringBackup.INI" without the quotation marks and Enter.
Open up Perfmon and check to see if your counters are showing up properly.
