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?

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

Windows is infested with corporate spyware, there is absolutely no need for its components to jack more than 50% of CPU and memory even when updating... Especially on clean installs, is Bill Gates trying to get GME shares to close his shorts?

Answer 4

nothing helps it's disabled but i can still see it eating up 50% of my CPU usage in processes

Answer 5

Hey, I just went to details in task manager and define the priority to low and the afinity to just one cpu, that reduces to 15% on my case. Hope I help.
