The listing, Gateway Windows Vista Home Premium 32-Bit has ended.
Here is a copy of Windows Vista Home Premium from Gateway. This can Re-Install or put a fresh copy of Vista on your Gateway computer. No COA or Keys included, if installing on a gateway machine you may not need one (not positive, I have a dell copy of xp that doesn't ask for a key if installed on a dell pc, however I don't have a gateway to try it on). Thanks for looking and good luck!
