Wow, 30+ years in IT. I can't believe this worked. Purchased the Win 11 OEM license and used it to downgrade Win 11 Enterprise from KMS key to Win 11 Pro fully activated. Worked like a charm! I highly recommend it. Oh and it worked with online activation even though the info here says you might need to call in to activate.
