try fangui, I used to use it on vista x64 on my M90, and I think win 7 on my M6300. you need to disable driver signing on start up but there was also a wee program which automatically moved the cursor selection on boot up for you, so as to do that
forget the name, try googling it on here
fangui is awesome
edit, foudnit, ready driver plus, see this old thread
