MBAM 1.41 "conflict" with Defender/UAC on startup removal

"A small bug was introduced in version 1.41 of Malwarebytes' Anti-Malware that prevents the startup entry for the Delete On Reboot script from being removed after it runs. This isn't a problem for most people, as Windows XP users do not notice this unless Windows Defender is installed. However, Windows Vista and Windows 7 users who have not disabled the UAC will be annoyed with a UAC popup when Windows starts up, and Windows Defender users at least used to be notified that Windows Defender had blocked the startup item".
