Windows 7 Starter is the edition of Windows 7 that contains the fewest features. The Windows Aero theme is not included in this version, and it is not available in a 64-bit variant. The desktop wallpaper, and Visual Style (Windows 7 Basic) is also not user-changeable. This edition is available pre-installed on computers, especially netbooks, through system integrators or computer manufacturers.
This edition is targeted towards enthusiasts and small business users. It includes all the features of Windows 7 Home Premium, and adds the ability to participate in a Windows Server domain. Additional features include operating as a Remote Desktop server, location aware printing, Encrypting File System, Presentation Mode, Software Restriction Policies (but not the extra management features of AppLocker) and Windows XP Mode.
Windows 7 Ultimate contains the same features as Windows 7 Enterprise, but unlike the Enterprise edition, it is available to home users on an individual license basis. Windows 7 Home Premium and Windows 7 Professional users are able to upgrade to Windows 7 Ultimate for a fee using Windows Anytime Upgrade if they wish to do so. Unlike Windows Vista Ultimate, the Windows 7 Ultimate edition does not include the Windows Ultimate Extras feature or any exclusive features.
Windows N Editions are available for both upgrades and new purchases, for the Premium, Professional, and Ultimate editions of Windows 7. The features in the N Editions are the same as their equivalent full versions as well as the same price, but do not include Windows Media Player. The cost of the N Editions are the same as the full versions, as Windows Media Player can be downloaded without charge from Microsoft for the N Editions.
VL Builds work with VLKs (Volume License Keys). Volume license keys can be used to activate multiple installations of the software without any mechanism (such as a product activation mechanism) checking the total number of installations. The license for the software will place restrictions on the use of the key. Typically the license will limit the key to a fixed number of installations which must only be within the licensee's organization and also place the licensee under an obligation to keep a record of the number of installations, keep the key confidential and possibly even require that the licensee organization makes itself available for a software licensing audit to verify that its use of the key is within the terms of the license. If a volume license key becomes known and used outside of the organization it is licensed to then this is regarded as copyright infringement.
