I called MS support once because some random dude managed to get my son's account registered under his "family", and then locked my son out of being able to update his own machine.

The MS support guy literally tried to get me to password crack the random dude's account. Like, he wanted me to help him guess the guy's password so we could log in as him and change his family settings.

That was the only "help" he could provide.

The Microsoft family/organisation situation is fucking ridiculous. If you somehow get enrolled in either, good luck ever ridding your device of it.

For literal years after leaving university, my windows install was still linked to my uni despite multiple attempts to fix it. All this, because I logged in using my university Microsoft account once.
