Ok, so you jump on your server to find out what’s spiking the CPU. You open Perfmon.exe, and throw on your investigation cap. But wait one second – where is the Process counter? Where is the Process Information counter? GONE!

Luckily there is a simple fix. Follow the steps below, and you will be able to hunt down that CPU spike in no time.

1. If you have Perfmon.exe still open close it.
2. Open regedit.exe (Start > Run> Regedit) and browse to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\PerfProc\Performance
3. Look for the DWORD key with the Name of “Disable Performance Counters”
4. Change the value from 1 to 0.
5. Close Regedit.exe and open Performance Monitor again. Your missing Perfmon Counters should now be back.

That’s it! Now hunt down that CPU spike.
