Where can I get Windows 10 product keys to upgrade my Windows 7?
Windows 10 will be a free upgrade but you still need a product key to install it. Microsoft has given away Windows 10 product codes that can be used by everyone to test and preview the upcoming Windows OS.
I heard some announcements from Microsoft that Windows 10 will be free for all Windows 7 users. I'm using Windows 7 in one of the computers in my home. Where can I get the Windows 10 product keys to upgrade my Windows 7?
Since Windows 10 will be free, can I use the same product key from someone else in all of my computers?
