ReactOS is a free and open-source operating system based on the best design principles found in the Windows NT architecture. Written completely from scratch, ReactOS is not a Linux-based system and it shares none of the UNIX architecture. The main goal of the ReactOS project is to provide an operating system which is binary compatible with Windows. This will allow Windows applications and drivers to run as they would on a Windows system. Additionally, the look and feel of the Windows operating system is used, such that people accustomed to the familiar user interface of Windows would find using ReactOS straightforward. The ultimate goal of ReactOS is to allow people to use it as an alternative to Windows without the need to change software they are used to.

An interesting non-Linux distro. This is an open source implementation of Windows that I wish would get more help and funding to keep it much more up to date and competitive to Windows. I have used it to try it out and I’m impressed. There are things lacking here and there because as I say with funding and it needs more people contributing bug fixes and helping the developers get further along. That’s what any open-source operating system needs. I can only think of the word admirable is what the developers here are doing. I really hope this project keeps going, I’d love to have an open-source and compatible implementation of Windows for everyday use, we’d not have to deal with Microsoft’s bs, user-unfriendliness and spyware.
