Does FSX work with Windows 2000? If so does Microsoft say anything about trying to activate without Windows XP. I don't want to purchase XP at this point I intend to purchase Vista when it becomes avaliable.Thanks Chuck

No. FSX will only run on a fully updated, WinXP SP/2 installation or the Vista Beta release.

There may be a way to actually get it to work (in much the same way that you can sometimes get Win 98 stuff to kind of work in XP with a bit of fiddling around), but I doubt it and I certainly wouldn't swear to it either. Besides which, the box states XP or Vista, nothing else, and MS always tell the truth don't they? :-)The thing is, it's becoming apparent that XP is not as good at running it as Vista will presumably be, simply because Vista will have greater capability to support all the funky stuff you'll need to go full throttle with the graphics and add-ons that will no doubt abound for FSX in a year or two's time, as even the best systems seem to be offering less FPS in FSX than they do in FS9 owing to all the graphical whistles and bells.Some have claimed that the frame rate counter is not an accurate depiction of what you are getting performance-wise with FSX, and while there does appear to be at least a tiny modicum of truth in that, if it walks like a duck, squawks like a duck and looks like a duck, then it's a duck. And if it looks like 10 FPS, then it probably is 10 FPS, although I must say that 15 FPS in FSX seems a lot more fluid than 15 FPS in FS9.So I'd say either stick with your OS and FS9, then get Vista and FSX (that is unless you can find a cheap copy of XP, in which case, get it and enjoy FSX, assuming you have plenty of RAM and a decent graphics card of the kind which seems to be running it okay).
