Do Windows 8 Store Apps (Metro) run in Windows 7 or XP?

Question

I want to know whether Metro Applications developed using Visual Studio 11 Developer Preview and .Net FrameWork 4.5 can run in Windows 7 or XP.

Not the normal Window

Answer 1

I'd be astonished if Win8 Metro-Style apps would ever work on Win7 - there is a huge amount of OS level infrastructure necessary to get those apps to work on Win8 that simply isn't available on Win7.

Having said that, people have figured out to write applications that can be made to work on both *nix and Windows with a recompile, so I imagine eventually it might be possible to write an app that could be recompiled to produce a metro-style version and a WPF/Silverlight version. But that technology simply doesn't exist at the moment.
