I just installed it two days ago and it fixed the problems I had with Windows 7. I don't want to go back because it's just going to be... Sh**. I really hope I can still use it!
I have Windows 7 Home Premium x64 on my Laptop, and 8.1 x64 on our desktop. Any tips on what I should do? I don't have a USB drive or a backup CD. Should I not install it?
