TIL (from a different part of the internet):
Windows 10 China Government Edition supports Mandarin Chinese only, region locked.
- OneDrive / Microsoft Cloud is removed,
- no Microsoft Store,
- Minimal or no telemetry to meet government demands,
- uses Chinese-approved encryption standards (unlike BitLocker),
- Entra ID / Azure AD Support replaced with local directory services,
- more localized control over system updates in Win 10 China Govt Ed.
I wonder if China asked to compile it themselves.
