Ever needed to run a windows application but you don’t have a Windows license? ReactOS allows you to do just that! From their website:
ReactOS® is a free open source operating system based on the best design principles found in the Windows NT® architecture (Windows versions such as Windows XP, Windows 7, Windows Server 2012 are built on Windows NT architecture). Written completely from scratch, ReactOS is not aLinux based system, and shares none of the UNIX architecture.
Here is a screenshot of LibreCAD running on ReactOS.
LibreCAD runs fine in reactOS and in my limited testing It doesn’t crash or did anything strange, the people of ReactOS has done a great job!
ReactOS is under heavy development at the moment and they are prepping for 0.4 release, here you can find more information ReactOS 0.4. Additionally, I would like to point out their Indiegogo campaign. ReactOS is a very complicated system and they need all the help in the world. If you find this a useful project and have used it yourself or planning to, you can support ReactOS financially, go to the IndieGOG campaign and read about more about the plan’s and goals.
