ReactOS™ is a FOSS effort to develop a quality operating system based on the architecture of Microsoft® Windows™ NT family of operating systems, that is compatible with applications and drivers written for it (NT4, 2000, XP, 2003, Vista, 7).
Not stable nor complete enough to be an alternative. The OS has been beta for decades.
ReactOS is in alpha since 1996, I don't think it should be an alternative, it dosen't have hardware support, it is slow and etc.
Not stable enough to consider. And it's still in alpha.
