This Powershell script list all the installed application on both 32 and 64 bit applications, particularly useful for people managing both 32-bit and 64-bit applications. This code also contains an exclusion array where you can exclude list of program that you don’t want to show.
- The function allows -ComputerName parameter so you can connect to any machines
- Application architecture detection (32-bit or 64-bit) using Win32_processor
- Output is Powershell console and GridView
Function call:- The computer name is mandatory to retrive the software list.
Get-InstalledApplication -Computername <Computername>

Function Get-InstalledApplication
