Powershell script to export all software information installed in a domain system

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
