Upgraded to Windows 10 from 32 bit to 64 bit Product Key Problem
So basically I Upgraded to Windows 10 from 32 bit to 64 bit because there was a problem on my computer's memory showing only 2.2gb usable which I made a thread about here 2.2gb Usable out of 4gb RAM. - Windows 10 Forums
So I was just successful in clean installing the 64bit but the problem now is, my OS is not activated. It's looking for a product key. So how do I get my OS to be genuine again? Will recovering the files in the windows.old backup folder solve the problem?
