Nano11 Builder - Sep. 2025 Release

Nano11 Builder is a PowerShell script to create a heavily trimmed-down Windows 11 ISO file.

In simple terms, Nano11 is a super minimal version of Windows 11. Now you can make your own Nano11 ISO.

Produced by NTDEV, the same person who is developing the very popular "Tiny11 Builder".

Note: Nano11 is an extremely reduced version of Windows 11, even the update function has been removed. If you want a reduced version of Windows 11 but with more Windows features (including the ability to update), you need to use "Tiny11 Builder".
