Here's a description of the issue...
I'm selling a used laptop to a client and can't activate windows 10 pro.
The laptop was originally purchased with windows 8.1 home and because it was for business and needed to join a domain, we purchased a copy of the pro version and upgraded accordingly.
When the time came, we upgraded to windows 10 pro without issue.
I reformatted and re-installed windows 10 to sell the pc, but now it won't activate with windows 10 pro with the windows 8.1 pro key, like it should. I get a message that it has detected a digital licence for windows 10 home, and for some reason i cannot break that link and activate the pro version.
the Windows 8.1 pro licence is 100% legal.. I have the original packaging and media that I purchased with the laptop.
Please assist.. I need to able to hand over the laptop soon.
