Windows: 100% disk usage

September 15, 2018

A few weeks ago one of our computers had a 100% disk usage issue. I can’t remember how my IT guys solved it, or the cause, but they did.

If you have the same issue, then try the instructions in this YouTube video: https://www.youtube.com/watch?v=mqbg4-3LIOQ — the critical information starts about 1 min 50 secs into the video.

To summarise the video:

  1. Open Resource Monitor, and check the Disk tab for what’s using the most resources.
  2. If it’s something called DiagTrack (with a bunch more information), open Task Manager, go to the Services tab, and stop DiagTrack (the Description has something like Connected User Services and Telemetry). This stops it from running for now, but when you reboot, it will likely start again.
  3. To stop it for good, you need to disable it. Open Services.msc, and find Connected User Services and Telemetry. Right-click on it and open Properties.
  4. Select Disabled from the Startup Type drop-down list, then click Apply and OK.
  5. Check Task Manager again to see if your system resources have been freed up.
  6. Reboot your computer.
