Yeah it sounds weird, right? Microsoft also has in the minimum requirements that it needs 20 GB of storage, which seems incredible to me. Maybe they are expecting companies to strip out more before embedding it in devices.

Anyway, for our purposes it seems Windows 10 IoT Enterprise is missing only very few things. I believe the Microsoft Store, Xbox App and Cortana are not on there. Supposedly you can add them back if you need.

But since I converted an existing Windows 10 Pro install, I even kept those (not that I want them...), and I'm still getting the security updates.

Not sure why it's called that but it's a completely normal daily driveable os, just heavily debloated compared to "stock" Windows. It's what I use, no issues.
