Tux Machines (TM)-specific
ReactOS is an effort to provide a Windows NT-like architecture that is compatible with existing drivers and applications. An easy way to look at it would be to say that it is a clone of the Windows OS (which is closed-source so it’s not possible to really clone it), when in reality, it’s an alternative to the Windows OS, with the difference that it’s a collaborative open-source project and it’s in its infancy. While the team behind ReactOS has been heavily developing this young operating system for over a decade, it is still in the alpha stage. However, there is a number of reasons that make ReactOS worth a look.
How It Looks (So Far)
So since this project is a rewrite of the Windows architecture, the ReactOS GUI is familiar to anyone who’s seen Windows 95, as ReactOS did start humble beginnings with the intention of cloning Windows 95. Since it sports a simple interface and strips itself of fancy bells and whistles, it’s lightweight and boots pretty fast.
Note that although the project isn’t ready for everyday use as stated on its website, there are many ways to try ReactOS.
