Hi, no Team is installed by user.
You can pre-install Team inside the computer with the Team Wide Installer, but that version load the Team inside the user profile to install it. It's not a local machine install.
For more information on the Wide Installer; https://learn.microsoft.com/en-us/microsoftteams/msi-deployment
The Teams MSI places an installer in %SystemDrive%\Program Files\Teams Installer on 32-bit Windows and %SystemDrive%\Program Files (x86)\Teams Installer on 64-bit Windows. Whenever a user signs into a new Windows user profile, the installer is launched and a copy of the Teams app is installed in that user's %LocalAppData%\Microsoft\Teams folder. If a user already has the Teams app installed in the %LocalAppData%\Microsoft\Teams folder, the MSI installer skips the process for that user.
