Your best bet is the Upgrade Home Premium. You qualify for the upgrade because you have XP on your PC now. You must do a Clean Install, you can not do an upgrade from XP. Read the tutorial that WHS gave you above about a Clean Install with a Upgrade Windows 7 Version
-- The Upgrade disk is exactly the same as the Full Retail disk. Microsoft just gives you a price break since you have already purchased XP. If you have any questions on installation, we will help. == One more thing. Don't buy one on Ebay. Do it at a regular store or a reputable online store.
