Do as Gordon suggests other have done, (& I continue to do), by buying a comp, setting it up for recording and then taking it off line from then on.
I was running an XP DAW for well over a decade and only changed when I required an updated interface, (various reasons), and all of the units available & in my price range required W7 to run.
I still have the XP & old interface - both running as well - and use it as a back up as well as to open & export tracks from old Cakewalk Pro Audio 9.3 "Bundle" discs.
Oh, and you could always run Linux with Reaper and use whatever comp. you want so long as the interface is compatible.
