Hey all,
I found a script online that does almost exactly what I need it to and it does it quite fast as well. Essentially it pulls ALL the software installed on a machine(s) but I would like to find only instances of certain software titles. Here is the slightly modified version of the script:
<#
.SYNOPSIS
Get-InstalledSoftware retrieves a list of installed software
.DESCRIPTION
Get-InstalledSoftware opens up the specified (remote) registry and scours it for installed software. When found it returns a list of the software and it's version.
.PARAMETER ComputerName
The computer from which you want to get a list of installed software. Defaults to the local host.
.EXAMPLE
Get-InstalledSoftware DC1
This will return a list of software from DC1. Like:
Name Version Computer UninstallCommand
---- ------- -------- ----------------
7-Zip 9.20.00.0 DC1 MsiExec.exe /I{23170F69-40C1-2702-0920-000001000000}
Google Chrome 65.119.95 DC1 MsiExec.exe /X{6B50D4E7-A873-3102-A1F9-CD5B17976208}
Opera 12.16 DC1 "C:\Program Files (x86)\Opera\Opera.exe" /uninstall
.EXAMPLE
Import-Module ActiveDirectory
Get-ADComputer -filter 'name -like "DC*"' | Get-InstalledSoftware
This will get a list of installed software on every AD computer that matches the AD filter (So all computers with names starting with DC)
.INPUTS
[string[]]Computername
.OUTPUTS
PSObject with properties: Name,Version,Computer,UninstallCommand
