CRILLER3: Win 7 might be as you say "ancient" but for some people it still works and why replace something when it works perfectly fine?.
PixelBoy: The irony here is, for me personally, that I mostly use Windows 10 to play games with, I only use an old laptop to download them with.
It's not a big issue to use some other computer to download, but it is kind of stupid that the download will be the problem, not the actual compatibility.
Anyway, when it comes to ancient OS, I think what this thread has so far completely missed is that Steam client will no longer work with Windows 8 either.
So if you have a system that is three years newer than some Windows 7 computer, it doesn't help at all.
For the record, I use Windows Vista on my Desktop, and it does the job that needs to be done there, so if something isn't broken, there's absolutely no need to fix it.
I wonder if there is some way to run Steam Linux client in some emulator in Windows 7/8?
That might help those who have no access to computers with Windows 10 or 11.
i use win 10 for all my gaming needs but i just love how everything just worked on Win 7, i had more Bluescreen on win 10 than my whole windows history ( 98SE,XP,win 7 and 10 ) for me Win 7 was THE best OS .10 is good havent tried 11 since my laptop cant run it ( says MS :S)
sorry i don't know much about linux OS but when im FORCED to switch OS im gonna try linux or something that has a good gaming support .
