This is actually the worst type of end-user.

Doesn’t make a ticket or notify anyone that there is a problem and then proceeds to try and fix it themselves incorrectly. When it does become a ticket, they won’t remember exactly what steps they took to troubleshoot and will waste 5x as much time from support staff trying to fix it than if they just didn’t touch it in the first place.

Guaranteed didn’t wipe the machine from the built in reset/recovery screen and instead used a windows installer that was created on a different computer and doesn’t have the correct network drivers in the image.
