MysterD: The problem w/ Windows 7 after a certain KB update was released, Win 8, and W10 was that Microsoft flat-out disabled Securom and Safedisc. TONS of games were protected w/ those DRM's.
You're gonna have to do some work-arounding and all, to either sign-off on the drivers yourself so they work or find a way to get around the DRM.

Other DRM's could possibly work - but some DRM's like StarForce won't work b/c StarForce is OS-specific and driver-specific - so it would be on StarForce to update their drivers so games using their protection work.
Or of course, it's up to the dev's to re-release their games on places like GOG without any DRM or release a patch to disable the CD/DVD checks - like say Larian has done w/ some of their games like Beyond Divinity.
Catventurer: I think you're missing the point that I've been making. -> If any game on my GOG wish list was to get released next week on a disc media format with CD check style copy protection, why would I want to purchase that when it's not going to work on my computer.
Some people equate having a game disc as a higher level of ownership as if that makes that ownership more real. This is meaningless when the end result is exactly the same as if you knowingly buy any UbiSoft game after its online service has been shut down. You cannot play it.
I only mentioned Windows 10 to make a point that CD check style copy protection is DRM, and people did have the ability to play their games taken away. Blizzard released a Windows 10 patch on their own, and the developers that I contacted offered Steam keys.
For the record, the only game I need to replace at the moment is D&D Ravenloft, but this is entirely a damaged disc issue. :/
Well, kind of (on ownership of disc-based games can be higher) - for modern games you buy digitally, they often require a service. And it's not like you get patch-files and keep those so you can up-date said game - as likely, that's all handled by a service (like Steam, Origin, UPLAY, etc). At least if you got it on disc - you do have a starting point there for the install. But, the disc could be useless - if patches, disc-check removals, client-app crap removals, and/or other stuff isn't given to the player/users.
A lot of newer & modern single-player games - you still need to connect to servers of the client-app (Steam, Origin, etc); have an account w/ that client-app service for verification purposes; maybe 3rd party server checks/stuff is involved (like say IO's Servers for Hitman games since 2016); maybe stuck w/ a 2nd client-app; and/or other madness.
Back in the day - a lot of these services did NOT exist. Until Steam, a lot of these games ONLY had only the disc-check, at least in their single-player portions. Let's keep that in mind here.
Also, back in the day - multiplayer often used TCP/IP/LAN for their MP; they didn't always use ded-servers and/or central servers.
Of course disc-checks are DRM - but they aren't say as ridiculous as client-app or online DRM; especially for SP-based games. For disc-based games that it's up to dev's to decide to put a CD-check/DVD-check or not for the retail release; and/or release a patch to the public to remove those checks if they had them there originally. A lot of times, hackers and whatnot eventually got around these disc-checks and released their own EXE files (and/or other files) anyways. I've bought games from retail that had no DRM before - such as Prince of Persia (Cel-Shaded Reboot) and Venetica on disc.
It's also up to dev's and pub's to re-release games on GOG or other sites w/out DRM - they should; especially if it's old. And since they like to not patch disc-versions of the game sometimes or not remove DRM from even say Steam-versions - yeah, they're banking on preservations re-buying the game AGAIN. They love re-releasing games on sites like GOG or Steam; re-mastering games (which can sometimes just feel like a paid-patch); and/or stuff like that - so they can make you buy the same thing...well, or close to the same thing - you already paid for all over again.
