You can disable Microsoft Teams from auto-starting in two ways—either directly from the Teams app or through your Windows startup settings.

🛑 Option 1: Disable from the Teams Desktop App

1. Open the Teams app.
2. Click the three dots (…) in the upper-right corner.
3. Select Settings.
4. Under the General > System section, uncheck the box labeled “Start Teams automatically”.

🛑 Option 2: Disable from Windows Startup Settings

1. Click the Start button in the lower-left corner of your screen.
2. Select Settings.
3. Go to Apps > Startup.
4. Find Microsoft Teams in the list and toggle it Off.

This will prevent Teams from launching automatically when your PC boots up.
