If it's the comedy post on reddit[0] then that's not how you determine which version of windows you're running on[1][2].

† btw, what became Windows 11 started development as just another Windows 10 feature update, and what gets branded as a "new release" vs an "update" is mostly a marketing decision.
The move from Windows 10 to Windows 11 came with some pretty severe restrictions on supported hardware, so the version jump in this case makes sense to me. It would be a lot more difficult to push an "update" which obsoleted so much hardware like that.
That's hardware, and just like with the Linux kernel you have some tough choices to make about what you continue to support. Apple rendered my Intel Mac Mini a brick because despite having a 64 bit CPU its BIOS/UEFI or whatever was 32 bit and I was stuck with MacOS 10.6, no way to upgrade to 10.7 Lion.
It's true if every developer reads MSDN /s
Some Java apps do `osname.startsWith("Windows 9")`

What Java devs get up to then that's their problem.
