A Powershell Script to remove Microsoft Teams Classic

Question

Anyone who can share a powershell script that will remove Microsoft Teams Classic? Current script i have is that it will detect if Teams classic is installed then it will proceed to remove.

Check if Microsoft Teams Classic is installed

$teamsClassic = Get-WmiObject -Query "SELECT * FROM Win32_Product WHERE Name LIKE '%Microsoft Teams%'" | Where-Object {$_.Name -like "Teams"}

if ($teamsClassic) {

Write-Host "Microsoft Teams Classic is installed."

$removeClassic = Read-Host "Do you want to remove Microsoft Teams Classic? (Y/N)"

if ($removeClassic -eq "Y" -or $removeClassic -eq "y") {

    Write-Host "Removing Microsoft Teams Classic..."

    $uninstallArgs = "/x $($teamsClassic.IdentifyingNumber) /quiet"

    Start-Process -FilePath "msiexec.exe" -ArgumentList $uninstallArgs -Wait

    Write-Host "Microsoft Teams Classic has been removed."

} else {

    Write-Host "Microsoft Teams Classic will not be removed."

}
```} else {

```yaml
Write-Host "Microsoft Teams Classic is not installed."
```}

# Check if new Microsoft Teams is installed

$teamsNew = Get-Package -Name "Teams Machine-Wide Installer" -ErrorAction SilentlyContinue

if ($teamsNew) {

Hi @Bob Pendon , here is a solution that worked for me, please give it a try and mark this answer as "Accepted" if it worked for you. Tested on Windows 10 with PowerShell 7.4.2 and 5.1:

$appName = "Microsoft Teams classic"
# A function to search for Teams installation
function Get-MSTeams {
    $path = @(
    "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", 
    "HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall", 
    "HKCU:\Software\Microsoft\Windows\CurrentVersion\Uninstall"
    )
    $entry = Get-ChildItem -Path $path | Get-ItemProperty | where {$_.Displayname -match $appName}
    return $entry
}

# Assign the result to a variable, so you can use .InstallLocation method further down and trigger uninstallation
$app = Get-MSTeams

# Check if the function has returned result (Teams is installed)
if ($app){

    # If yes, prompt for action
    $prompt = Read-Host "Microsoft Teams Classic installation FOUND. Uninstall? [Y/N]"
    
    if ($prompt -eq "Y"){
        Set-Location -Path $app.InstallLocation
        Start-Process Update.exe -ArgumentList "--uninstall", "-s"
        Write-Output "`nUninstalling..."
        Start-Sleep 5

        # Keep checking if Teams is still installed, until it's not
        while (Get-MSTeams){
            Start-Sleep 2
            Write-Output "Uninstalling..."
        }
        Write-Output "`nMicrosoft Teams Classic successfully uninstalled!`n"
    }
    else {break}
}
else {
    Write-Output "Microsoft Teams Classic installation NOT found!"
}

# Set location to home directory
Set-Location $HOME

In Powershell

CD "C:\Users<Username>\AppData\Local\Microsoft\Teams"

Start-Process ".\Update.exe" -ArgumentList "--uninstall -s"
