Very nice robust construction fan-less mini computer for light industrial application and even an HTPC. My computers came with a Kingdel user account already setup, which I chose to not keep and setup my own. First open Settings - Update & Security - Activation, and be sure it says "Windows is activated with a digital license". You may need to connect it to the internet first for this to work. Then, go to Recovery - Reset this PC to wipe windows clean and start over fresh. Other than the extra step to set it up, been pretty happy. The little Celeron processor is a bit slow, but gets the job done.
