There's Windows 10 LTSC, which gets security updates til 2027. And IoT Enterprise LTSC, which gets security updates until 2032.
"But should you even use those versions?!? They are not meant to be installed on a desktop PC/laptop" - idk, it's either this or Win11.

What do you mean by that? You don't lose gaming performance when you use win10 over win11. Why would you?
