The other editions are focused at other markets, such as the developing world or enterprise use. All editions support the 32-bit (IA-32) processor architecture and all editions except Starter support the 64-bit (x86-64) processor architecture (64-bit installation media is not included in Home Basic edition, but can be obtained from Microsoft).

According to Microsoft, the features for all editions of Windows 7 are stored on the machine, regardless of what edition is in use.
