I've accidentally installed Windows 10 LTSC 2019 N on my server, but my product key only works for the non-N version of LTSC 2019. Reinstalling the OS would be a pain in the arse as I'm connected to the computer remotely. Is there a way to change it to the normal LTSC 2019 version?
You can try to change the regkeys to non N and do an inplace upgrade using 17763.107 non N LTSC ISO (or higher).
Got round to finally upgrading the server as we were taking a break from playing on it. Followed your exact steps, and it went perfectly. Thanks for the wee guide.
