Hi,

I have this script that gives me all the programs that are installed on remote computers in the network.
It works really great, except for one thing. It gives me also all the MS updates and I'm not really interested in that.
In the output the script produces, the updates do have one common value: (KB
Is there a way that I can manipulate the output, so it shows all the installed programs, except everything that has "(KB" in it's value ?

import-module activedirectory

$Computers = Get-ADComputer -Filter * -SearchBase "OU=Computers,DC=company,DC=lan" -properties SamAccountName | `
Select -ExpandProperty samaccountname
$Computername = $Computers.Replace("$","")
  
foreach ($Computer in $ComputerName) {
	if ( Test-Connection -ComputerName $Computer -Count 1 -ErrorAction SilentlyContinue ){
	$Export = "C:\Scripts\Software_Inventory\CSV\$Computer.csv"
		write-host "$Computer is pingable"
        $RegBase = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine,$Computer)
        $RegUninstall = $RegBase.OpenSubKey('SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall')
        $RegUninstall.GetSubKeyNames() | 
        ForEach-Object {
            $DisplayName = ($RegBase.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$_")).GetValue('DisplayName')
            if ($DisplayName) {
                New-Object -TypeName PSCustomObject -Property @{
                    ComputerName = $Computer
                    ProgramName = $DisplayName
					}
                }
            }| Sort-Object "ProgramName" | Export-Csv $Export -nti -delimiter ";"

You could make a simple change based on how the KB values are displayed

import-module activedirectory

$Computers = Get-ADComputer -Filter * -SearchBase "OU=Computers,DC=company,DC=lan" -properties SamAccountName | `
Select -ExpandProperty samaccountname
$Computername = $Computers.Replace("$","")
  
foreach ($Computer in $ComputerName) {
	if ( Test-Connection -ComputerName $Computer -Count 1 -ErrorAction SilentlyContinue ){
	$Export = "C:\Scripts\Software_Inventory\CSV\$Computer.csv"
		write-host "$Computer is pingable"
        $RegBase = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine,$Computer)
        $RegUninstall = $RegBase.OpenSubKey('SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall')
        $RegUninstall.GetSubKeyNames() | 
        ForEach-Object {
            $DisplayName = ($RegBase.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$_")).GetValue('DisplayName')
            if ($DisplayName -note like "*(KB*" -and $Displayname -ne $null) {
                New-Object -TypeName PSCustomObject -Property @{
                    ComputerName = $Computer
                    ProgramName = $DisplayName
					}
                }
            }| Sort-Object "ProgramName" | Export-Csv $Export -nti -delimiter ";"

The code above is based on the assumption as you indicate that KBS have "(KB" in their name, as such we exclude them from the results.

If you want a listing that is the same as what you see when you open "Program and Features" in the Control Panel, query for a couple more properties besides DisplayName (namely systemcomponent and parentkeyname), and then you can filter as shown in the example below.
$list = Get-ChildItem HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
$list | Get-ItemProperty -Name displayname,systemcomponent,parentkeyname -ErrorAction SilentlyContinue |
 ? { !($_.systemcomponent) -and !($_.Parentkeyname) }
