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.

Thanks Ray - I want to revive my old 2011 Hackintosh (mac / PC) to life and possibly add some HDD's and use it as a backup. The mac portion of that computer still has Mountain Lion OS.

Btw check out Windows LTSC (Long Term Service Channel). It's a much less bloated version of Windows and is supported much longer (if you'd like to keep running an older version of Windows). Windows 10 LTSC 2021 is supported until 2032.
