Windows 11 Enterprise Ltsc 2024 Build 25941 Update. You cannot use uup dump to create enterprise ltsc, also the leak is an official release from microsoft to select people who have gained access (under non disclosure agreements, i think?) instead of a hack job iso made by someone. This is as far as i see release preview other choices in.
I am currently using windows 11 iot and enterprise (23h2), but i will wait until lstc release comes out. Check out each one to determine the best option for you.
