Developer NTDEV has demonstrated a functional build of Windows 11 running from a standard 700 MB compact disc. The experimental installation uses an unreleased utility called Pico11 to shrink the operating system down to 699811840 bytes. But the creator has not shared a release timeline for the tool or listed which system components were removed.
The project tests how far Windows 11 can shrink while preserving basic desktop functions. Standard Windows 11 installations regularly require over 20 GB of drive space, making a 700 MB target an extreme reduction. NTDEV filled 699811840 bytes on the disc, taking up virtually the entire physical capacity of standard CD media. The developer confirmed that the modified system boots properly and still launches basic software applications.
NTDEV developed the compact image using a private creation tool named Pico11. The developer kept the technical modifications secret, leaving it unknown whether networking protocols, driver libraries, or core security tools were stripped from the image. NTDEV has not committed to a public launch for Pico11, treating the project purely as a technical proof of concept for operating system reduction.
