Since my last Windows 10 Update, CompatTelRunner.exe is causing 100% CPU usage after Windows start. This results in not being able to use my computer for a long time. How can I fix this?
Windows OS Build is 19042.1052

CompatTelRunner.exe is a component of Windows Compatibility Telemetry,
periodically sending anonymous usage and performance data to Microsoft
developers to help improve Windows.
Its default location is C:/Windows/System32/, which you should verify.
A good tool for this is
Process Explorer.
If the folder is wrong, then this is actually a virus.
First verify the state of Windows by running sfc /scannow.
If this doesn't help, you can disable it by one of these methods (reboot is required):
Run Group Policy Editor (
gpedit.msc) and position to Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds. Double-click "Allow Telemetry", select Disable, then click OK.Run Task Scheduler (
taskschd.msc) and position to Task Scheduler Library > Microsoft > Windows > Application Experience. Right-click the "Microsoft Compatibility Appraiser" task, and select Disable.Edit the registry: Run
regedit, position toHKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection, right-click the right pane and select "New > DWORD (32-bit) Value". Name itAllow Telemetryand set its value to0.
Process Hacker is a good task manager. You can use Process Hacker to stop program.
Danger! If is a important program, do not stop it. Please talk with your PC administrator.
