Username appearing in login screen. Can't remove it! Tried everything, including Regedit..

Occasional Visitor


Can anybody help me?

I've got a username that I just can't remove from the Microsoft Teams login screen.

They used my computer once, and I don't have their password, so can't login.

They're the top account in the picture below.


  • Not listed in control panel > Manage your credentials.

  • Not listed in  Settings > Accounts > Email & accounts (or school/business accounts there)

  • Not listed in: Computer\HKEY_CURRENT_USER\Software\Microsoft\IdentityCRL\UserExtendedProperties\

I have

  • deleted and reinstalled Teams

  • Cleared the Teams cache.

Is there anything more I can do?!Thanks so much for any suggestions!!


I've found this in the logs:
