The Elder Scrolls II: Daggerfall
works on windows 7 pc, tested 4/29/2025

I wish they'd be more accurate as to games what work on windows 7, some that clearly should work are saying minimum windows 10.

Daggerfall is a DOS game so it runs in Dosbox emulator. Any Win7 machine should be powerful enough for that.
Considering it's a free game, gog.com might not be eager to support it for such an old OS. (Microsoft ended mainstream support for Windows7 10 years ago)

Besides running that on DosBox from GOG...

There's also Daggerfall Unity engine-port you can run Daggerfall on, if you're trying to run in on Windows w/ more features:

Just, if you use that - make sure you meet the requirements.

You can check the following thread for games that work on Win 7 or ask other users. GOG is not supporting Windows 7 anymore so they have to remove that from the store page even though many games still work
