Hello, 1st post here and I need some help. Merry xmas btw Background info: I bought a new motherboard (Gigabyte z87-hd3). Upgrade for xmas ho ho ho I still have the old motherboard ( MSI z68s-G43 (G3)) and I can swap between them atm. I have a genuine Windows 7 Pro (got it for free from uni and should be good for another 3-4 years). Windows started asking for activation and today I was greeted by the black background with "this isn't genuine windows"...etc message. Then I ran the slmge -rearm in cmd as admin and rebooted. Now when I check the licence info it says I have 3 days to auto activation. I read here & there that SLP 2.1 is used by windows to tell if the board is the same ? Is that what is happening here ? (or is that only for oem's like DELL, Lenovo...etc pc's ?) Windows put the values in an SLP 2.1 table on the bios on the MSI board. So now the Gigabyte bios has an empty SLP 2.1 table or no SLP table at all ? The main question is: Will the process of transferring SLP tables from the old board to the new one work ? Is this what I should do ? I'm a newbie to the process, so any guide you can point me to would be of great help P.S. I would love to keep my current windows 7 install. It's already set the way I like and has all the stuff I need installed...etc you know what I mean. That is why I am looking modding the bios slp tables.
