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 :)

    Got it, thank you. I guess I was too harsh at MS. I still think it should be easier to disable this, tho.

    Tried...

    Task Scheduler (application experience and Customer Experience) Disabled

    Group Policy (Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Allow Telemetry) Disabled

    Services (Connected User Experience Telemetry) Disabled

    It still runs causing this

    I usually know when it's started to run as the USB Keyboard/Mouse inserted in the surface dock start disconnecting and reconnecting - as soon as that happens, I have to launch Task Manager and shut telemetry down.

    However, there is nothing I can do when it's rebooting. Gets to the login screen and freezes (or sometimes the screen is just black for about ten minutes), the processor is hot when I touch the top of the laptop - clearly, it's pushing over the 100C limit for that processor.

    Just renamed CompatTelRunner.exe to CompatTelRunner.old - I suspect that if I have to run SFC or DISM it will replace the 'corrupted' file or a Windows update might do the same, so it's probably going to be an ongoing battle.
