Safely Remove Hardware fails when GOverlay is running and I try to remove my USB key (also Rufus can't write to USB to create a bootable flash drive).
Event viewer:
The application \Device\HarddiskVolume8\Programs\GOverlay\GOverlay.exe with process id 8612 stopped the removal or ejection for the device USB\VID_13FE&PID_5100\07072457B4D7A635.
