Windows 10 Universal Apps backwards compatibility

Question

Will Windows 10 Universal Apps be backwards compatible and be able to run on Windows XP/7/8/8.1 ??? I assume it shouldn't be too difficult for Microsoft to run it in a windowed player that supports universal app api's.

Answer 1

Currently they are not backwards compatible. And I wouldn't expect them to be - the goal is to move everyone from old Windows to the latest, Windows 10, so I assume that's where the focus will be.
