December 15, 2025 – NTDEV, creator of Tiny11, has released Nano11 – an extreme Windows 11 superlite build. The ISO shrinks to ~2.3GB (installed ~6GB), perfect for low-end PCs, virtual machines, or embedded devices. Based on Windows 11 24H2/25H2, it's open-source via GitHub script.


What is Nano11?

Nano11 is a PowerShell script that creates the most trimmed-down Windows 11 image possible. It goes beyond Tiny11 by removing core services for maximum lightness – ideal for testing/VMs, not daily use.

ISO up to 3x smaller than stock Windows 11 – boots fast on old hardware.
