Reinstalling Windows 7 after installing Windows 10 (With keys?)
Windows 10 was released today and I'd like to install it on my custom built desktop for testing. However, I would like to know if I can go back to Windows 7 after updating to Windows 10. I did a bit of research and found out that there was a roll back option in Windows 10 menus, but I also read that it would be available for only a month after installation. I then thought that just reinstalling Windows 7 with the original installation disc and product key would be all I needed to do to get my computer back to working order. However, a friend of mine said that windows would not let my product key be used for anything else other than windows 10 after being upgraded (at least after 30 days).
I believe lots of people have asked similar questions, but I've had a great deal of trouble finding a definitive answer. Knowing if the same rules apply to 8.1 would also be helpful. Thanks.
