hello, I'm new here
I would like to know witch copy of windows 7 should I buy.
I'm currently have win vista premium 32-bit. I am gonna uppgrade to win 7 home premium 64-bit. I know that you can only uppgrade from 32 to 32 and from 64 to 64. But, can you do a clean install with an upgrade DVD?, since I already have a vista key, or I have to buy a full version?
