Hello,Im deciding to reinstall windows vista home premium 64 bit since thats the original operating OS this computer had but im running windows 7 on it. When i check the product key on my computer with a key finding program, it displays a different product key compared to the sticker on the bottom of my computer. I recently found out that the bottom sticker product key is the OEM which was meant for windows vista home premium. So what i am wondering is if i can do a clean install of windows vista home premium using the OEM disc even though my computer displays it has a different product key on windows 7? Will a OEM disc work with the product key i have on the sticker?

This is the cheapest way to buy windows. Large PC manufacturers like Dell, HP etc. (collectively called royalty OEMs) install windows on millions of such PCs. The main characteristics of such systems are:The license agreement and support agreement is between you and the PC maker, not MS.Activation by the end user is not required. Windows is preactivated at the factory by the OEM using images and standard SLP keys.Your copy of windows is locked to that PC. The license is not transferable.OEM system builder is what you get when you buy from say Newegg or from a local "white box" vendor. It too has the characteristics of Royalty OEM windows. Although it is possible for an individual to buy a System Builder copy, the license requires that the software be installed using the OPK (OEM preinstall kit) and then resold.Retail version is what you buy from a retailer like Amazon or Bestbuy. Its a full price version that comes packaged in a retail box with a retail product key. It has to be activated online via MS servers using the key on the box, it is not tied to the PC it was first installed on, though it can only be used on a single computer at a time. And, MS directly provides the support for it. It is also more expensive than OEM copies.As far as functionality is concerned, theres no difference between any of the versions above, given any specific edition (i.e. between OEM pro and retail pro, or between OEM ultimate and retail ultimate).sevenforums.comWindows 8 OEM is a whole different ballgame.License agreement transfer of license of Windows 8 http://personaluselicense.windows.com/en-US/default.aspx
