Here are two ways to prevent Windows 11 from installing Teams and Chat. The newest client OS from Microsoft has a Chat icon in the taskbar that opens the Teams app. However, it is not included in the setup media by default. 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.
When Microsoft adds a new component to the OS, it often gives IT professionals and consumers options to control over new behavior. Sometimes such options are a group policy, in some cases it is a registry tweak.
For the Chat icon, you can remove it in the Settings app, or by the Configures the Chat icon on the taskbar policy. Obviously, that does not save you from installing Teams.
To stop Windows 11 from downloading the Teams app, you need to modify the Registry and add a special value.
