TinyKRNL is a bootleg live Windows XP environment, which was created by Kenneth. The project originally started in early 2006, but this build in particular released on October 18, 2008. It was added to the archive on December 8, 2022. It is based on PicoXP. It is currently the smallest XP bootleg in the collection, and one of the very few available on floppy disks.


TinyKRNL utilizes Windows Native Mode, which is most notable for being used in the chkdsk tool in vanilla Windows, alongside a custom shell named the Native Command Line Interface (NCLI) to actually run things. Because the Win32 subsystem has been removed, no native Windows programs will run, even if they are command line. In addition, there is also no NTVDM, which means DOS programs will similarly not work. Programs would have to be written from scratch to be used with this OS.
