GoKawiilDeveloper NTDEV shrinks Windows 11 to fit on a 700MB CD-ROM
Developer NTDEV, creator of the Tiny11 project, built a proof-of-concept tool called Pico11 that compresses a working Windows 11 install into a single ISO sized under 700MB, small enough for a CD-ROM. The demo retains a functional desktop with Calculator, Settings, Notepad and Paint, though it uses an older, lightweight Task Manager and strips out Windows Update and servicing features.
