There are a lot of LPE's in Windows too. Remember that it started out as a single user operating system, it took a long time to get software on board to not always running as admin.
Was NT ever single user? I thought they built it with network/multiuser in mind.
(I agree that maybe applications could’ve been built for 3.1/9x and expect a single user, but the os expects multiple).
Considering the amount of crazy shit even just user access allows you to do, by design, an LPE is not even really necessary.
