Do you mean like Windows 7? No, it's only coded for AMD and Intel processors (x86).
If you mean a port of Windows Phone, it's still no. Processor architecture's okay(well, not quite, but it's close) but Windows Phone isn't open source, so how would you port it without source code?
I wouldn't mind having Windows Mobile 6.5 on my OV. I liked Microsoft outlook and notes and the ability to make an email immediately into a calendar event. I wish there was an email client on android that could do similar.
You can now make your Android mobile device work like a desktop computer!
It's finally here! Windows 7 for Android! You can now emulate a desktop pc on your Android device.
