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.
