I'd be very surprised if it wasn't. When I installed the preview it was pretty much the same as Windows 7 but with an annoying start screen. Sadly I uninstalled it pretty snappy as it just slowed me down. I can appreciate it's design for tablets though, but not PCs.
Ah, wish you'd tested it with UO before you uninstalled. It was just that I noticed that there were a lot of games that they already had listed as compatible - but nothing yet for UO.
Yeah, we'll have to wait and see what shakes out with it. I like to be on the cutting edge of technology - but not with operating systems. I tend to wait and see what the reviewers say, the techys, and give them time to work out the bugs.
Well, with luck, perhaps someone else will give it a try. I might give it a try myself, but not on my primary computer.
