IoT Enterprise has longer support, and under the hood it's basically all the same. Otherwise you wouldn't be able to trick Windows into believing it's an LTSC version while it's a GAC one, then have the installer just turn it into an LTSC version with zero issues. Did the same trick on my Win10 install, from 22H2 GAC to 21H2 LTSC with the only things being restored to default being a handful of tweaks. At this point I forgot that I switched the SSD after cloning, and that I switched Windows to LTSC. Shit's this transparent nowadays.
