3 ways to list installed software with Powershell

Here’s 3 little code snippet to get the software installed on the local machine using powershell. Usefull when scripting setups and deployment !

Slow but really complete.

Get-WmiObject -Class Win32_Product

Based on the software in Add/Remove Programs. Fast but may miss some software.

Get-WmiObject -Class Win32Reg_AddRemovePrograms

Based on the software registering in the registry for uninstall. Fast but may miss some software.

Get-ChildItem HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall |
% {Get-ItemProperty $_.PsPath} |
where {$_.Displayname -and ($_.Displayname -match ".*")} |
sort Displayname | select DisplayName, Publisher

Catch you next time and keep it bug free !
