Listen its Windows 10 with redesign and under the hood changes. It is not a full new windows version.
Even windows 10 license keys work
That's a somewhat bizarre argument. Windows 7 was essentially Vista SP3 with a new UI and name to disguise the stink of failure, so was that not a "full new Windows version" either? Not to mention that 8 and 10 are pretty much just evolutions of 7 with new UIs and "under the hood changes" too. By that logic, the last actual "full" new consumer edition of Windows was XP, since it marked the switchover from the DOS-based versions to the NT kernel on the desktop. Assuming we're not counting Windows 2000, which wasn't technically designed for desktop users, even though many (including me) ended up using it because ME was terrible. Of course, this is rather irrelevant in terms of driver support, as trying to install drivers from even 7 or 8 on Windows 10 generally results in failure, even if they are basically the same OS with a fresh coat of paint. Windows 11 doesn't look to be changing anything in terms of what Microsoft do to create a "new" version of Windows. Perhaps you're only just noticing it now because there's far better in-depth coverage of the "under the hood" parts of a new Windows version now than there was in the mid-2000s.
As for license keys, Microsoft don't care about selling Windows to consumers any more. Sure, they'll do it if you really want, but Windows 10 can straight up be activated with a Windows 7, 8 or 8.1 key too - no previous Windows installation required. That functionality was added in the November
2015 update. All they want is people using the latest version so that they can harvest their data. Hell, even not activating Windows 10 at all doesn't actually stop you from using it. The countdowns to when Windows would stop working if you didn't activate are long gone. Now all it limits you from doing is customising your desktop.
This is pretty standard stuff. I have a RTX470 in my 3rd PC and the driver version only goes up with 395 or something like that.
Nvidia fully dropped support for Fermi in 2019. That's nine years after the GTX 470 came out. Still a damn sight better than the six years that the Fury cards have gotten.
