Must be some old titles, it's pretty rare for a 32-bit Windows game to flat out not work in Windows 10. I'm even able to run Incredible Machine 3 (a game from 1995), albeit without CD audio. DOS and 16-bit Windows games however require an emulator like DOSBox. Many 3D games from the mid-late '90s and early '00s relied on now esoteric hardware accelerators and APIs (like Glide) or GPU features that behave differently on modern hardware than the games expect. These might require a wrapper like nGlide or dgVoodoo 2. Check the entries for your games on the PC Gaming Wiki (www.pcgamingwiki.com).
