This is a search for all games that are compatible with Windows 7, but not 10. It apparently doesn't include games released in the year, but hopefully they will be Win10 compatible.

Search through the list of results and pick out your games. The search is courtesy of MaGOG. There is an option to import your list of games, so you might be able to further restrict the list.

Hopefully identifying games that you own is easier than comparing two lists for differences.

Tomb Raider 2 is not listed, but there is an explicit "not supported" warning in the game page.

Of the others, some do have actual issues (Nox and Dracula 3 required third party patches for me). Others will probably work, but no promises (I had no trouble with Psychonauts and Vampire the Masquerade: Redemption. Wing Commander 3 and Syndicate Wars are DosBox powered, so there is no reason why they won't work)

There are some games that do work on Windows 10, even if they aren't advertised to do so, because they might not work on all systems. I have a large library and most of them worked on W10.

Hmm,...if I understand you correctly, you do know which five games out of your 182 games aren't compatible with Win10, yes?

Well, how about simply copying your games into a spreadsheet, and mark those who are incompatible, with an asterisk, or something like that?

And I get it, you'd rather have the possibility to get these five games shown online on your GOG account, but a spreadsheet works, can easily be updated, can be arranged alphabetically (or by compatibility - if you set a common mark for these),...and if you use something like OneDrive, it can be accessed online from any of your devices.

GOG doesn't list games as "Windows 10 compatible" but as "supported on Windows 10".

I understood it the other way around: OP sees that the total number of games supported on Win 10 is five titles less than those supported on Win 7 but has no way of telling what those five titles are, except for checking all the game pages manually.

Hm,...but then I have to ask: where does he see that difference in numbers?

I mean, maybe I'm just extremely lucky in that regard, but when I switch between the different Win versions as filters for my account, GOG always shows the same (= the total) number of games, that I own.

Is that different for you? With which I mean: does your number change, depending on what Win version you set as filter?

One game I know of personally that I have not been able to get working on Windows 10 is Rainbow Six. I hope GOG will solve this issue at some point. Maybe Soon™

In my experience, and from reading general experiences, incompatibility with Windows 10 is a very rare thing. A lot of times people jump to conclusions when they have an issue and blame the OS. It would probably be more effective for GOG to label Windows 10 issues, rather than slowly over time list Windows 10 on every game page.

Thank you all for your replies!

Good point, I never tried that filter in the library before, but no, it seems that the number shown is always the total amount of all games in the library (even when you choose OSX or Linux). I guess you'd have to count the games manually to notice a difference.

It is rarely updated(basically as I or others add them and I update the main list), but I am working on and off on a list of games that work/play on Win 10 here in one of the first few posts(hopefully it might help you or others, or you could even add to it if you know for sure a game runs on Win10):

I'd made the question question late last year: https://www.gog.com/forum/general/list_of_gog_games_that_dont_work_on_windows_10
