Microsoft Compatibility Telemetry Using High CPU

Question

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?

Answer 1

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 :)

Answer 3

I've checked process is NOT running and tried to rename or delete CompatTelRunner.exe located in the C:\Windows\System32 AND in C:\Windows\WinSxS, I receive a "FILE ACCESS DENIED" error-- "You need permission from TrustedInstaller to make changes to this file"

I can't even delete files from my own system?

This does not seem to work on my system. Even when renaming the file using admin cmd it says I don't have the permission. Seriously, **** Microsoft, I'm glad I don't have to use Windows that often.
