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 :)

    Microsoft. C'mon! Anything that runs at startup needs to be extremely careful about CPU usage. When I log in to my PC, I'm almost guaranteed to be doing something--a real human wants to interact with their PC. I want to quickly get to work, or check my e-mail, or buy something, or play a game. I'm guaranteed to want to interact with my PC during that first minute of startup.

    So for this telemetry process to run--along side Chrome updating after I launch my browser, while my cloud storage is attempting to sync, and MS Defender has decided it has an urgent update or scan it wants to run... just schedule your telemetry at a different time!

    In my case (windows 10 Pro 22H2), the file "CompatTelRunner.exe" doesn't exist in "C:\Windows\SysWOW64".

    What can be the other possible location? or How can I find that?
