If your PC actually can't run Windows 11 (older than Nehalem/Bulldozer) then you should:
* fresh install 10 21H2 LTSC IoT using "methods" - this will keep receiving Windows patches until 2032 (although 3rd party software may end support sooner)
or
* move to a supported Linux distro (Debian 13 with XFCE would be a safe bet)
or
* buy a new computer because 15 years is pretty old for a PC
If your PC can run Windows 11, but Microsoft don't support it (1st-7th gen Intel or AMD FX-Zen 1) then use 11 24H2 LTSC IoT.
If your PC does support Windows 11 but you're finally sick of Microsoft's bullpoop... 11 24H2 LTSC IoT.
Basically use 21H2 LTSC for old machines, and 24H2 LTSC for new machines. I honestly believe MS makes this version available (and so easy to activate) just to keep HN-types happy. Far less crap, still get security updates, and you'll probably reinstall in a few years once software support gets in the way or a new Windows release adds features you want (but won't be pushed because LTSC.) It actually makes Windows acceptable to use and acts like versions before 10 (it's one branch which gets patched, not upgrades every 6 months)
Of course moving to a better platform (Linux or BSD) would be preferred, but sometimes we still need to use Windows...
