Everything Windows is so entrenched in eating its own dogfood, so it probably will never change. But what I wouldn't give for a ground-up POSIX-compliant Windows OS. It's stupid, it's unrealistic, but it would be so, so awesome.

For me it's not even about being unix-like (though sounds nice). I would just want them to get rid of all the legacy garbage and start from scratch. They have nice design language, good programming environment, multiple platforms - everything is dandy. The only problem is all the stuff left for compatibility reasons.
