Microsoft Teams. Teams (Personal), Teams (Work and School), Teams (New). A year or so ago you night have had all three of these installed at the same time..

and that's AFTER they changed the names of Personal and Work. Before that, you'd have Microsoft Teams and Microsoft Teams. One was purple with a white T and the other was white with a purple T.

If you tried to login with the personal version, it would error-out but not give any indication you may be using the wrong version. Let's be real. NO ONE is using Teams in their personal life. /rant

They're just infuriating on every level when it comes to naming things.
