When you first plug in a new micro:bit, it runs a special demonstration program that shows off some of its features. We call this the 'Out Of the Box experience' program.
If you want to restore the micro:bit to it’s OOB state, for example when starting a new class or issuing a micro:bit to a student, you can follow the OOB instructions on microbit.org
