Powershell for the list of installed application in a domain

Question

Can any one help me with the script for the below scenario.

I have all my computers joined in domain with static IP address assigned. Using any script can I get the list of installed softwares in those computers?

Answer 1

Hi,

This script can do that for you. Assume computer names in your domain are computername1, computername2 and computername3:

$computernames = "computername1","computername2","computername3"  
 $array = @()  
 foreach($computername in $computernames){  
     #Define the variable to hold the location of Currently Installed Programs  
     $UninstallKey=”SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall”   
     #Create an instance of the Registry Object and open the HKLM base key  
     $reg=[microsoft.win32.registrykey]::OpenRemoteBaseKey(‘LocalMachine’,$computername)   
     #Drill down into the Uninstall key using the OpenSubKey Method  
     $regkey=$reg.OpenSubKey($UninstallKey)   
     #Retrieve an array of string that contain all the subkey names  
     $subkeys=$regkey.GetSubKeyNames()   
     #Open each Subkey and use GetValue Method to return the required values for each  
     foreach($key in $subkeys){  
         $thisKey=$UninstallKey+”\\”+$key   
         $thisSubKey=$reg.OpenSubKey($thisKey)   
         $obj = New-Object PSObject  
         $obj | Add-Member -MemberType NoteProperty -Name “ComputerName” -Value $computername  
         $obj | Add-Member -MemberType NoteProperty -Name “DisplayName” -Value $($thisSubKey.GetValue(“DisplayName”))  
         $obj | Add-Member -MemberType NoteProperty -Name “DisplayVersion” -Value $($thisSubKey.GetValue(“DisplayVersion”))  
         $obj | Add-Member -MemberType NoteProperty -Name “InstallLocation” -Value $($thisSubKey.GetValue(“InstallLocation”))  
         $obj | Add-Member -MemberType NoteProperty -Name “Publisher” -Value $($thisSubKey.GetValue(“Publisher”))  
         $array += $obj  
     }   
 }  
 $array | Where-Object { $_.DisplayName } | select ComputerName, DisplayName, DisplayVersion, Publisher | ft -auto
