pds41: For the reasons outlined in my post. Your question has previously been asked and answered in this forum.
Also, Heretic II does work on Windows 10. As will most of your games on optical media. You'll just need to learn to tinker a bit, like everyone else does. For further reference, see the other threads on Windows 11.
Jon_Irenicus_PL: But for instance Fallout 3 was released in the XP era (so the 2nd last operating system before Windows 10, as nobody really ever cared about 8) and it doesn't work on Steam anymore, you need to buy it from GOG. So new OS' can decimate your library. In this case, if you bought Fallout 3 on Steam before you switched to 10, you are screwed.
Plus, GOG themselves have said that new OS' are problematic
How is Windows 11 better in that regard???
EDIT actually, it appears that Fallout 3 launched in the 7 era, meaning it existed on a last or second last (depending on if you count 8) OS before 10, but Steam users can't play it
Technically, decimation would be 1 in 10 items not working. Looking online, you can get Fallout 3 on Steam to work, you just have to be prepared to install some patches and do some tinkering. The GoG version comes with updates already installed. Unless you're completely unprepared to help yourself (in which case, buy an Xbox or other console), you can get it working.
Anyway, as I said, your "question" has largely been asked an answered in the following threads:
https://www.gog.com/forum/general/are_you_ready_for_windows_11_to_rebreak_all_these_old_games_again/page1 https://www.gog.com/forum/general/windows_11_are_you_planning_to_update/page1 https://www.gog.com/forum/general/windows_11_updating/page1 https://www.gog.com/forum/general/windows_10_support_ending_in_2025/page1 As you'll see from reading these, there are three key take homes.
1) It currently looks like Windows 11 is essentially a "feature update" for Windows 10 with added TPM requirements (not a problem if you're running a laptop or recent processor)
2) Nobody really knows what Microsoft are planning, but it would appear highly unlikely that (other than rollout bugs) compatibility will break.
3) Everything seems to work on early builds
For your games:
- Dosbox and ScummVM will continue working. Their dev teams will add fixes if needed to get them working on 11, but
there's no expectation that fixes will be needed
- Games using earlier versions of DirectX than 9.0c may need a DirectX wrapper (as they do today) to work properly. DGVoodoo2 is your friend here
- Optical media will need the copy protection stripped out to work (as they do today). Doing this is not hard
- 16-bit windows games are harder, but as today, you can either set up a VM or use something like BoxedWine to get it working
In all my years of using Windows 10, there's only one game that I haven't made to work (Wallace and Gromit in Project Zoo). However, some kindly members of this forum pointed me in the direction of BoxedWine, and I've got some ideas as to how I can get that to work.
