Some of the old software before 2010 may not be able to install/run normally on x64 or Windows 10 systems. Be aware of it before purchasing it.
Windows 7 Starter is the edition of Windows 7 that contains the fewest features. 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 release candidate versions of Windows 7, Microsoft intended to restrict users of this edition to running three simultaneous programs, but this limitation was dropped in the final release. This edition does not support more than 2 GB of RAM.
