Dear Tinh nguyen,
- Yes. Each physical client PC still needs its own Windows license, even in diskless bootrom setups.
- Yes (generally). OEM licenses per PC can be sufficient if each license is correctly assigned to each device.
- No change. Streaming Windows from a server does not remove or reduce licensing requirements.
- Not strictly required, but recommended. Volume Licensing is usually the safer and more compliant option for cafes/bootrom environments.
- No specific bootrom document. Microsoft covers this under general Windows licensing, VDI, and imaging rules in Product Terms.
Best Setup at your case (Use one valid Windows license per PC (preferably Volume Licensing for cafés) + central boot image is fine as long as every device is properly licensed).
Best,
M.
