what is the difference between different windows Service packs?
If I downloaded Windows 7 Pro SP3 and I had Pro SP1 and used my CD key would it work?
Also should I trust ebay for a copy of windows 7 ultimate? Surely £60 for a full unopened/unused copy is too cheap? (I need XP mode but I'm a little tight on Cash..)
Will paypal give me some safety? (I've never had to make a refund claim with paypal in the past...)
