I've recently moved my copy of a graphics package from an old PC with Win 7 (dual core pentium, old spinning hard disk, bought as a cheap refurb box 4-5 years ago) to my newish laptop (Win 10 enterprise, 4 core i7, more RAM, nice fast SSD). It struggled a bit on the old machine and I hoped for a step forward, specially with the SSD. No such luck. After a bit of messing about, it works slightly less badly in Win 8 compatibility mode, although the software is dated 2015, so contemporary with Win 10 & claims Win 10 compatibility . Even closing all other programs down & doing the best to give it a free run, Win 10 & current hardware is less effective than Win 7 & obsolete hardware.
An OS is just a means to run more interesting, useful or entertaining software, and for that Win 10 is a step backwards. YMMV.
