What is Microsoft Compatibility Telemetry? Everything you need to know

Windows uses hundreds if not thousands of background processes to run as it does. These background processes usually don’t reveal themselves to the end-user, but at times, they can come into the spotlight for using too many system resources.

In this article, we’re talking about the Microsoft Compatibility Telemetry process’ high CPU usage and how you can fix any problems the process might cause.


What is the Microsoft Compatibility Telemetry process?

In layman terms, the process is a part of the Microsoft Compatibility Appraiser. It compiles and sends usage and performance data back to Microsoft for analysis and further improvements to the user experience. 

While the process — CompatTelRunner.exe doesn’t usually use many system resources, sometimes you can find it using way too much CPU. Fortunately, this is only a temporary thing and usually goes away on its own after some time. However, if the CPU usage is sustained for you, you can use the solutions mentioned below to try and fix the problem.

How to fix high CPU usage? 

Here are a few fixes you can try out if the process uses too much CPU for a longer time. 

Run a malware scan

Since the process usually runs pretty quietly in the background, the chances are that this is malware or virus posing as one instead of being a Windows process. In such cases, run a full, in-depth system scan using your antivirus or antimalware of choice, and if you find anything suspicious, remove it from your PC.


Perform a Disk Cleanup

Disk Cleanup is an integral feature of Windows. It can help iron out many issues that may otherwise impact your system’s performance, including repairing any processes using too much CPU.
