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 :)

I went into the properties and checked the digital signature... @Microsoft why the heck are you putting items with unauthenticated attributes into the OS? As someone who's owned servers, run linux, and just bought a mac... YOU LITERALLY HAVE 0 REASON TO USE 100% OF THE CPU. It's embarrassing to be so hypocritical "oooh, you need to spend $500+/year to code sign your apps to not trigger Windows Defender" meanwhile you're pushing literal unsigned spyware onto our computers.
