A Beta is avaliable on the official Windows website beware it is a Beta, and Microsofr have a reputation for not getting things right the first time. drivers for a lot of different softwares arent avaliable yet, but if you really want it, get it from there this new OS could overwrite your XP etc, so have a backup, or a spare harddrive you can put it on, OR split your harddrive in two, some free software can do this.
