How to Stop Teams From Opening on Startup (or Uninstall It)

Method 1: Disable Microsoft Teams From Its Settings

If you want to keep Teams installed on your PC but prefer to launch it manually when necessary, follow the steps below.

Step 1: Press the Windows key on your keyboard. Then, type Microsoft Teams and click Open.

Step 2: Once launched, click on the three-dot icon at the top bar next to your profile icon. From the drop-down, choose Settings.

Step 3: In Settings, under System, uncheck the box for Auto-start Teams.

Microsoft Teams should no longer auto-start each time you turn on your PC.

Method 2: Stop Microsoft Teams From Opening on Startup Using Task Manager

You can use the Task Manager to adjust the startup status of Microsoft Teams if you want to stop the app from launching automatically. Here’s how.

Step 1: Press the Windows key on your keyboard, type Task Manager, and click Run as administrator.

Note: Alternatively, press the Windows key + Shift + Esc to open Task Manager.

Step 2: From the side pane, go to Startup Apps > choose Microsoft Teams > click Disable at the top.

You can also use this method to stop any other app on your Windows computer from starting automatically.

Method 3: Disable Microsoft Teams Using Registry Editor

This method is more complex than the one above. We also recommend backing up the Windows Registry before proceeding with the steps below. 

Step 1: Press the Windows key on your keyboard, type Registry Editor, and click Run as administrator.

Note: Alternatively, press the Windows + R keys to open the Run dialog box, type regedit.exe, and click OK to open Registry Editor.

Step 2: In the top address bar, enter the following path:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

Note: You can manually navigate to the section too.

Step 3: Find and right-click on the com.squirrel.Teams.Teams key. Then, click Delete.

Step 4: In the confirmation window, click Yes.

Finally, reboot the system to implement the changes.
