Windows XP has a built in performance monitor that examines various areas of your system. Most of us have little interest in this sort of performance monitoring application.
Geek translation: it’s more for businesses than it it is for home users. This can slow down your PC so turn it off.
Click “start”, “Run” and type in cmd. If you did everything correct, your window will now look like this…
Click “OK”. You now see a window that looks like this…
Just type in diskperf -N like seen in the above screenshot and press enter on your keyboard. Don’t worry, even though there was no message telling you Disk Monitor was disabled, it was.
This will have no effect on XP or later. On Windows 2000 and earlier it was possible to disable disk performance counters because of a small impact on performance. On later systems these performance counters cannot be disabled. The command is only provided to maintain compatibility with old scripts.
Run the command “diskperf /?” to see that this is the case.
