Nano11 compresses Windows 11 install footprint to as little as 2.8GB — 'extreme experimental script' is 3.5 times smaller than Tiny11 and comes with 'none of the fluff'

Nano11 Builder.

NTDEV has introduced the Nano11 Builder for Windows 11. This is a tool that allows Windows 11 testers and tinkerers to pare down Microsoft’s latest OS into the bare minimum. With this new release, the developer has significantly pushed the boundaries of their prior Tiny11 releases.

Nano11’s extreme pruning of the official installer disk image from Microsoft produces a new ISO “up to 3.5 times smaller” than the original. The example Windows 11 standard ISO shown in the Nano11 demo was 7.04GB, but after the PowerShell script had done its stuff, you can end up with a 2.29GB ISO.
