The discs can be played on Windows 10. I did it myself through Seasons. It was some work to get Windows 10 to accept SafeDisk DRM which is why it won't let you play it, since MS disabled Windows 7 and Windows 10 from being able to play any disc with SafeDisk as the copy protection.
Also, Securom on the discs or store versions like Fun with Pets etc. is why those later discs starting with H&M won't be able to be installed. There is a long work around to get Windows 10 to play the discs since it's your pc and not MS's, but it does take a tutorial. But yes, you can play the game with discs.
