Windows 7 Starter is an edition of Windows 7, and contains the fewest features out of every version of Windows 7. It is only available in a 32-bit version and does not include the Windows Aero theme. The desktop wallpaper, and visual styles (Windows 7 Basic), are not user-changeable. In the beta versions of Windows 7 Starter, there was a restriction that the user could only run three simultaneous applications at the same time, similar to the restriction in Windows XP Starter and Windows Vista Starter. This feature was however dropped in the final release.
