doesnt the ltsc version target enterprises and stuff and you cant just use your home/pro license you need a whole diff license and many anticheats and steam will end support for 10 once it ends support
LTSC is "only" available through an enterprise licensing through Microsoft or its partners, which means you can probably ask a company or organization for one of their volume keys, and will probably be the only Windows where you can permanently disable Recall...
Like seriously, I had problems disabling telemetry in Windows 10 Pro because it kept re-enabling them, but not in the LTSC version.
