Folks, before you start playing around especially later with BIOS flashing (if we ever get the BIOS), you should backup your real Windows 8.1 key.

This is stored in the BIOS in the ACPI>MSDM table.

See this link for how to dump it using RWEverything.

Please note! Do not just write this down and think it will work. The MSDM table is signed and encrypted. What you need to do is SAVE this entire table as a .BIN file using the RWEverything program. This way later, you can write the .BIN file back to the BIOS using RWEverything.
