If I have a valid license for XP & am doing a new system build, can I install XP, then for $40, upgrade to Win 8, then downgrade to Win 7 (if I don't like 8?)
You'd have to buy Windows 7 separately. But if you are coming from Vista or XP, you will almost certainly be satisfied with Windows 8. For the most part, the only people complaining about 8 are people with 7 who don't like Metro.
I have a laptop with Windows 7, and two computers with Windows 8 (preview), and to me it's the same experience in essence...just have the metro interface that I then need to click to the desktop if I want to go there.
