It's proven that there is a number of officially announced bare Windows 8 (Windows 8 Core) editions:
- Windows 8 Core
- Windows 8 Core N (proof: EU commission ruling)
- Windows 8 Core China Edition (confirmed by Steve Guggenheimer)
Possibly there might exist:
- Windows 8 Core Single Country
- Windows 8 Core Single Language
Please describe, what limitations do different editions have (e.g no MUI, activation issues etc.)?
