Powershell script to uninstall applications

If you are looking for a script to uninstall applications remote on windows 10 desktop computer or windows server 2016 computer then you are at the right place, here in this article we explain how a Powershell Script can uninstall applications on multiple remote computers.

We can uninstall any software using Powershell script, there are two methods available, using the WMI method and uninstall registry string. Generally, windows administrator deal with many servers and desktop machines every day as part of their work and they work on product uninstallation and upgrades, using Powershell script user interaction is not required, one can automate the uninstallation process and same with uninstalling registry string, here are the simple steps this article explains how this script can uninstall any software without any user interaction.

We need to create a text file for remote computers list that we are going to uninstall applications, here I have created a text file named as allservers.txt and saved it in location C\temp\allservers.txt

function UninstallApplication{
   param
   (
   [Parameter(Position=0, Mandatory = $true, HelpMessage="Enter CompuerName", ValueFromPipeline = $true)] 
   $ServerName,
   [Parameter(Position=1, Mandatory = $true, HelpMessage="Enter ApplicationName", ValueFromPipeline = $true)]
   $Application
   )
  
   $Object = New-Object PSCustomObject
   $Object | Add-Member -MemberType NoteProperty -Name "ServerName" -Value $ServerName
   $Object | Add-Member -MemberType NoteProperty -Name "Application" -Value $Application
   return $Object
}
 
$Allservers = get-content -Path "C:\temp\Allservers.txt"
 
foreach($oneserver in $Allservers)
{
 
    $ApplicationName = $oneserver.applicationName
    $MachineName = $oneserver.servername
 
    $application = Get-WmiObject -Class Win32_Product -MachineName $MachineName -Filter "Name='$ApplicationName'"
    If($application -ne $null)
    {
        $output = $application.Uninstall()
        If ($output.ReturnValue -eq 0)
        {   
            Write-Verbose -Verbose "[$(Get-Date)] - $MachineName  $($application.name) Uninstalled!"
            
        }
        Else
        {   
            Write-Error -Verbose "[$(Get-Date)] - $MachineName  $($application.name) Uninstallation is failed!  Error code: $($output.ReturnValue)"
           
        }
    }
    Else
    {
        Write-Verbose -Verbose "[$(Get-Date)] - $MachineName Can not find the $ApplicationName"
       
    }
}

Usage of the script:

we need to run this function on a Powershell on a server or desktop machine where you have administrator privileges, and also on the remote computers where you are uninstalling the software.

C:\UninstallApplication -ServerName win2016 -Application MSOFFICE
