How to Obtain a Valid Windows 7 RTM Product Key

1. Buy a new computer. When you purchase a new computer from Dell, Sony, etc. with Windows 7 preinstalled, the computer comes with an official product key. When purchasing a brand new computer, the OS is already installed, meaning the consumer does not have to activate it and in most cases will never see the product key. When Windows 7 is preinstalled, the product is typically on the computer itself as a sticker or can be found within the computer's packing and information.
2. Purchase an official copy of Windows 7 from Microsoft. Microsoft sells Windows 7 as a digital download, immediately available for download upon purchase. In these cases, the Windows 7 product key will be emailed to the address provided upon purchase.
3. Purchase Windows 7 from a third-party store. Windows 7 is sold in a number of electronic and office supply stores, as well as online department stores. When purchasing a physical copy of Windows 7, the product key is provided in the retail box.
