Windows Server – Disk Performance Missing From Task Manager?

KB ID 0001203 


If your machine is struggling, a good place to look first is the performance tab on ‘Task Manager’

Task Manager NO Disk Statistics

Here you can see CPU and Memory Stats and how our network cards are performing, but wheres the disk stats?


Before you can see them you need to enable them, open a PowerShell, (or an administrative command window). and run the following command;

diskperf -y

Task Manager Enable Disk Performance 

Now re-open task manager and go to the performance tab and you can see the stats for the hard drives;

Task Manager Show Disk Performance

I can’t think why, but if you wanted to turn this off again issue the following command;

diskperf -n

Task Manager Disable Disk Performance

  1. disk part and perfmon is disabled for task manager as it will consume resources and hammer the server. You can instead use resource monitor

  3. Great command, I always come back here via google because I forget it 😀

    BTW, you dont need to run it in powershell anyway.

    But at some point CMD will be replaced by default by powrshell

    I wonder which clever-clogs at Microsoft decided to remove it in the first place
