If using wmic:root\cli>csproduct list full:
Description=Computer System Product
IdentifyingNumber=[Redacted]
Name=Surface Pro 2
SKUNumber=
UUID=2BFAD366-F2BB-F143-5198-92033DB687D4
Vendor=Microsoft Corporation
Version=1
Your Version number makes it look like there is corruption, not just incorrect values. I'm wondering if whatever it is that did this could have just stopped at this phase and not actually damaged your BIOS. Also, I wonder if the UUID gives a more specific clue about what it could have been but I can't tell if it is product specific or machine specific.
