anyone know of opensource xserver soft for windows

im curently using x-win for a x server session for windows but (though not expensive ) its hard to justify the expense when i allready have vnc its just that stripping just the app is so much faster

havnt found anything myself but theres so much soft and info out there didnt know if any of you might have seen something

thanks

I tried finding one, too, but I wasn't too lucky. I think that cygwin has something, though, although I haven't examined it too much.
