ReactOS is an open source effort to develop a quality operating system that is compatible with applications and drivers written for the Microsoft Windows NT family of operating systems (NT4, 2000, XP, 2003).

ReactOS 0.3.7 Released

Version 0.3.7 got delayed due to a couple of blocker bugs, however they are fixed now and we are ready to release.

This release along with the rest of the 0.3.x series is still considered alpha quality software.

ReactOS 0.3.7 continues further work on the main three principles of current ReactOS development: bugfixes, compatibility and stability.
