The desktop wallpaper and visual styles (Windows 7 Basic) are not user-changeable. Microsoft originally intended to restrict the edition to running three simultaneous applications but this limitation was dropped.
- This edition is available pre-installed on computers, especially netbooks, through system integrators or computer manufacturers using OEM licenses.
- Windows 7 Home Basic
- Windows 7 Home Basic is available in “emerging markets“, in 141 different countries. Some Windows Aero options are excluded along with several new features.Home Basic, along with other editions sold in emerging markets, include geographical activation restriction, which requires users to activate Windows within a certain region or country.
