About this tag
The lzms tag on WindowsForum.com covers community projects that produce ultra-minimal Windows 11 images, primarily the Nano11 Builder and related tools from developer NTDEV. These threads discuss how lzms tools shrink a standard Windows 11 ISO to as little as 2.29 GB and an installed footprint under 3 GB by aggressively removing inbox apps, drivers, servicing infrastructure, and security features. The resulting images are intended for virtual machines, lab testing, and legacy hardware experiments. Discussions highlight the trade-offs: extreme size reduction comes at the cost of no Windows Update, reduced security, and limited compatibility. The tag also references the broader Tiny11 family and the technical methods used to achieve such compression.

    Nano11: Tiny Windows 11 ISO (2–4GB) and Lean 8GB VM Install

    I installed Windows 11 from a nano‑sized 2.4 GB ISO and the finished system used just 8.36 GB on disk — a result that compresses a typical Windows 11 footprint to roughly two‑thirds smaller than a regular install, accomplished with the community project Nano11 Builder and a few post‑install...
