What is CompatTelRunner.exe?

CompatTelRunner.exe is the executable process for ‘Windows Compatibility Telemetry’ service, which collects and sends usage and performance data to Microsoft. It is present on all Windows 10 machines by default and was installed on Windows 8/8.1/7 as an update described in KB2977759. The company claims that the process helps refine the user experience on Windows, but many users claim that it is a massive resource hog that slows down their computers, especially at startup.

It is executed using the Windows Task Scheduler and is enabled by default, but you can disable it without any problem.
