PowerShell Script: Uninstall Microsoft Teams from a workstation

This script will uninstall Microsoft Teams from a workstation, it will also work while running under a different user, in case you need to role it out via a RMM solution but would work as a Group policy too

# Check if script is running with administrative privileges
if (-not ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) {
    Write-Host "This script must be run with administrative privileges."
    Exit 1001
}
