React OS (operating system) is a completely free opserating system for PC's based around the same technology windows uses. this means that unlike Linux it is (or it
will be once completed...) entirely compatible with ALL windows programs.
an example of the operating system, which, as you can see it pretty much identicle to screens of Windows NT (around which XP was also built)
This operating system is only in what is called 'Alpha' stage at the moment, it it still literally being built, it has been in production for many years, but is only being produced by part time coders, much akin to how linux began, with many people contributing to the overall.
If like many people you enjoy computer games on the PC, but dont always want to have to rely on / pay for Microsoft operating systems, on which the vast majority of games will run, unlike Linux which requires 'go-between' software to run games and windows applications ReactOS will run them nativly.
