Once I have my (now ex) girlfriend at home, and she wanted to check her email. So she used my computer to login on Outlook and just do her thing for work. Little did I know that logging to Outlook actually added some new account on my computer (for the same windows User), and it started to sync all the stuff from my ex's workplace.

Fast forward 1 month later, we broke up, and I was still seeing her stuff popping on my computer, as "recently opened" in the file explorer, or "recommended" in the start menu. Since we recently broke up it was really affecting my mood to be constantly reminded of her.

I struggled for like 3 months to find the option to deactivate it. I even considered formating my computer. It really felt like a private space violation, like my computer wasn't even my own, and all that just with a naive email login followed buy a ton of implicit behaviors.
