Are you certain that the setting did not hold? The reason I ask is because if you use a reg setting to disable the LLTM/R settings, they will actually be disabled but the boxes will still remain checked. You can test this by doing a deployment, reboot into the BIOS and change the date to 2 months ahead, then reboot back into Windows. Sometimes you might have to change to 6 months ahead, as I had found that 30 days isn't always enough.
