Fellas, if you were hoping SE is some kind of a bloat-free version of Windows 11 then you can save yourself some time and forget about it. In "unlocked / non S-mode" state (EmodePolicyRequired=0) it's basically Windows 11 Pro without Store and Teams, but with some annoyances instead (Control Panel blocked and un-removable watermarks). Nothing else is different, no Win32 Notepad or Calculator is present (like with LTSC) etc. You can get the same result by installing Pro version and removing Store. In "locked / S-mode" state (EmodePolicyRequired=1) system is completely unusable, default limitations are even more strict than with Windows 10 S. I'm guessing it is intended for the school administrator to unlock things on the tenant level and without it you are locked tight.
