- takeown /f “%WinDir%\System32\CompatTelRunner.exe” /a
- icacls “%WinDir%\System32\CompatTelRunner.exe” /Grant Administrators:f
- Then, you can delete the file using the command del “%WinDir%\System32\CompatTelRunner.exe”
- Alternatively, you can rename it to something else to leave a backup. To do so, use the command: ren “%WinDir%\System32\CompatTelRunner.exe” CompatTelRunner.old
