What is Microsoft Compatibility Telemetry?
Microsoft Compatibility Telemetry is essentially a data collection service. It collects technical data about your device, system components, application performance, and how your hardware works with Windows. Microsoft uses this information to identify potential issues, fix bugs, and ensure smooth compatibility for future updates—a goal that’s theoretically noble.
Problems arise when this process sometimes decides to run unexpectedly or repeatedly, leading to excessive CPU usage and excessive disk usage. For users with older or slower hard disk drives (HDDs), this can often lead to catastrophic 100% disk usage, rendering the computer virtually unusable until the process is terminated or shut down. As many users discuss on the Microsoft Compatibility Telemetry Reddit threads, resource spikes are a major problem.
Click Ctrl-Alt-Del to open Task Manager, and you can see how many resources Microsoft Compatibility Telemetry is using as follows:

4. Select and double-click on Allow Telemetry on the right panel, as follows:
5. Select Disabled, then click OK to save the setting, as follows:
After completing the steps above, Microsoft Compatibility Telemetry will no longer work, and your computer will no longer slow down due to Microsoft Compatibility Telemetry.
In fact, there are other solutions to this problem, for example, you can use third-party software. However, disabling Microsoft Compatibility Telemetry using the Group Policy Editor is the easiest way.
