Microsoft Teams sign-in window that appears at startup.

If Microsoft Teams keeps reinstalling itself on your Windows PC and launching itself at boot, there’s a solution. You can’t just uninstall Microsoft Teams the usual way: You have to uninstall it twice.

It’s silly, but that’s how it works. Specifically, you’ll have to uninstall both “Microsoft Teams” and the “Teams Machine-Wide Installer.” If you just uninstall the Microsoft Teams application, the machine-wide installer will reinstall it every time you sign in to your PC. To completely uninstall Teams, you have to remove both applications.

To uninstall both, head to Settings > Apps > Apps & features on Windows 10.

Under Apps & features, search for “Teams.” Uninstall both Microsoft Teams and Teams Machine-Wide Installer.

You can also use the classic Control Panel to uninstall these applications. Head to Control Panel > Programs > Uninstall a Program, search for “Teams,” and uninstall both Microsoft Teams and Teams Machine-Wide Installer.

You’re done! The next time you sign in to your PC, Teams won’t automatically reinstall itself. It’ll stay deleted from your system until you download and install it on purpose.

As Microsoft’s website notes, Teams will also be uninstalled if you uninstall Office from your system. Microsoft Office seems to automatically install both Teams and the Teams Machine-Wide Installer in many cases.
