Enabling Task manager Disk Performance Counters
 

1. Ensure Task Manager is closed.
    
2. Launch the Command Prompt using the "Run as Administrator" option.
    
3. Enter the following at the Command Prompt:
    diskperf -Y
    
4.  Hit Enter.
    
5. Close the Command Prompt.
    
6. Re-open the Task Manager
