I decided to do a fresh install on my SurfaceBook 2 - Ever since, I keep getting 'Activate Windows' watermark.
I then troubleshoot, and I get the 'Windows have been activated with a key linked to your microsft account' - That lasts anywhere for 1 hour to 8 hours before it comes back.
Some observations:
Product ID: 00330-62989-08643-AAOEM
Product Key shows up as XXXXX-XXXXX-XXXXX-XXXX-CWH2D
Error Code: 0x8007232B
What is really interesting is, that my OriginalProducyKey on the bios ends in 9W3GQ
