Amma, dont take the comments personally - you just happen to be asking to install a closed system on an open phone so to speak Allthough you can get windows 95/98 etc working on the device, they are not really usable.... Win7 is a different beast, and apart from it really not being at all usable even if someone could miraculously figure out how to port it, the phone itself is just not designed to run the micro-software. (And doesnt have the three h/w buttons)
