Microsoft Compatibility Telemetry Using High CPU

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 :)

    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.

    this is the only solution that actually worked !!! thank you

    I found this exe file under C:/Windows/System32 and I can't rename it or change its permissions without the approval of group Trusted Installers. Oh, and the Task Scheduler does not contain it either.

    You have to take control of the file first (ownership).

    Right click and select 'Properties' then the 'security' tab and click 'Advanced'

    At the top you will see the owner is 'TrustedInstaller' - click 'change' and make yourself the owner

    Close the dialog, right click the file again and then reopen the 'security' tab once more and click 'Edit'

    Give yourself read/write permission and then you can rename the file.

    Be aware that if you run DISM or SFC Windows will probably 'fix' the 'corrupted' file and you will have to rinse and repeat each time - also some updates might replace it.

    So far, it's the only thing that has actually worked for me.
