recovery compression

About this tag
Recovery compression is a technique used in Windows 11 debloating projects like Tiny11 and Nano11 to significantly reduce ISO and installed image sizes. By applying LZX or similar compression algorithms to the Windows component store and recovery files, these tools can shrink a standard Windows 11 image from several gigabytes to around 2-3 GB. This trade-off sacrifices some serviceability and update capabilities for a much smaller footprint, making it appealing for lightweight VMs, legacy hardware, or users who want a minimal Windows installation. The compression is applied during the image rebuilding process using Microsoft's DISM and other official tooling, and it is a key feature in recent Tiny11 25H2 updates.
