Hi, whenever I startup, I notice that Microsoft Compatibility Telemetry uses about 50-80% of my CPU which stops after a minute or so. Is this normal or should I be concerned?

Hi Tqkend

I'm Juliet and I'll do my best to help you.

The Windows Compatibility Telemetry contains technical information about how the device and its associated software work. It sends data to Microsoft on a regular basis in order to improve the system and improve the user experience. To resolve your issue about its high CPU usage, you can disable this service in the Task Scheduler by following the steps below:

  1. Click Start, type Task Scheduler, and then press Enter.
  2. On the TaskScheduler window, go to this path: Task Scheduler Library\Microsoft\Windows\Application Experience.
  3. On the Application Experience folder, look for Microsoft Compatibility Appraiser.
  4. Right-click on it, select Disable, and then confirm to complete the process.

I hope it helps! Let me know the results.

Have a nice day ahead and Stay safe always :)

Hey I found a fix, I just went to that file location of that "Telemetry"

In my case it was at : C:\Windows\SysWOW64

  1. Renamed "CompatTelRunner.exe" -> "Something.exe"
  2. Then Ended the task on taskmanager then it didn't start up.

Of course I am not sure if it will have any long term effects. Do it at your risk :)

    This thread is pure gold....

    had the same issue which caused my laptop to be unusable, my calculation software was not able to do even simple tasks such as graphical integrations......

    I noted something for the CompatTelRunner, you have to end the task in the task planner before you disable it. If you disable it directly, it will remain active, and even worse, launch on it's own, when I ended the process and than disabled it, it remainded closed for good.

    But just for safety measure, I altered the trigger and renamed the file as well.

    Thanks for this thread, you saved me a lot of trouble!
