Well, reactos is perpetually in alpha and has been as long as I can remember it.
Darned thing is brokenish, and a good many of these are bugs that should be reported to ROS devs rather than asked here. While I did argue against it, there is no roadmap for when ROS would be in a usable state unlike windows 8.1.
I'd say that the logic is still valid, and the closevotes seem like a good idea.
As for the last one, I don't remember the dev in question but it also recommends asking their forums. This is a good idea.
So, feel free to vote to close these, and we'll follow up with our closehammers shortly.
