React Operating System

ReactOS® is a free, modern operating system based on the design of Windows® NT series (including XP and Vista).

Written completely from scratch, it aims to be binary compatible with Windows software and hardware drivers.

Straightforward familiar user interface with little to no learning curve.

Please bear in mind that ReactOS 0.3.13 is still in alpha stage, meaning it is not feature-complete and is not recommended for everyday use.
