My in-place upgrade from Win7/8 to Win10 1607 works on a bitlocked machine. I'm using the out-of-the box in-place task sequence. Somewhere in that magic it is able to suspend the boot-time bitlock PIN requirement we have on our laptops. It successfully reboots during the upgrade process without prompting for that. However, right after the upgraded OS is complete, it restarts the machine before hitting the last step--Installing Updates. It is here that it starts prompting for a PIN again, before Install Updates. Does anyone know how to make it continue to suppress the PIN requirement until it is completely done with the task sequence, including the Install Updates? MS Premier Support is so far stumped.
