Poor UI Defaults
The UI design fails to meet the Windows default interface look and mechanics. It appears to be from Safe Mode from the Windows Vista era. The title text is also not centered horizontally (but would be if there was no bevel). The border displays a bevel whereas Windows 10 has no bevel but a single pixel border. See attached screenshot. I think aesthetics really goes a long way when presenting a software product to the end customer and this would help to be cleaned up.
