Prevent Windows 11 from installing Teams and Chat

Here are two ways to prevent Windows 11 from installing Teams and Chat.

Windows 11 automatically downloads it shortly after the installation of the system as an APPX package.

The Chat button in the taskbar simplifies the Microsoft Teams experience. Using the button available right in the taskbar by default, you can start chatting with your friends on Teams with one click. It supports text messages, voice, and video calls. Simply click the Chat button and start a new conversation.
