Eh, you have win 8, just use it. You would have gotten used to it by now instead of bothering with a bunch of swap meets or shady websites. I ended up getting used to Win 8 within a week. Some of the Metro apps are pretty good, like the netflix one. Much snappier than the PS3 one I've been using. Plus task manager is better as well.
Windows 8.1 shows notes that they are working on providing better kb/m interfaces, so I'd wait for that.
