The issues i get through linux come from my failure to understand it
I’d argue that’s true of any user’s experience with any OS, including what you just experienced with Windows.
Getting out of S mode is actually very trivial, certainly moreso than many of the changes one might be expected to make in Linux. There’s a certain type of user that “S Mode” is intended for. You’re not that user, and Linux is likely to be a negative experience for that user.
Limits app installations to those on the Microsoft Store and also disables Terminal / Powershell.
Makes for a super simple tamper-proof system that is similar to a Chromebook but a little more versatile. It’s a good solution for users who are all-in on the Microsoft ecosystem - think those who live their lives in Edge, Word, Excel. The restrictions keep them out of hot water.
Those restrictions are obviously annoying to those who want to install regular x86_64 apps from an .exe / .msi file or use Powershell / Terminal / CMD.
