Getting a filtered list of installed software in powershell

I ran it elevated in PowerShell ISE and called the function using just Get-InstalledSoftware as I only wanted to query the machine it was running on. The script doesn't terminate gracefully when it runs out of results to process but it does the job.

Thanks @RickC.

Very strange on my part. I had to Restart my computer for another reason and then I re-ran the Script in PS ISE and it worked !

Additionally, you can get most of the information that the Function outputs by just running the following commands with or without the filtering criteria . . .

Code:


Get-ChildItem -Path 'HKLM:Software\Microsoft\Windows\CurrentVersion\Uninstall'
Get-ChildItem -Path 'HKLM:Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
Get-ChildItem -Path 'HKCU:Software\Microsoft\Windows\CurrentVersion\Uninstall'

The HKCU (HKEY_CURRENT_USER) registry hive only applies to the user currently logged in, whereas the function that I linked to uses HKU (HKEY_USERS) so it applies to all user profiles actively loaded on the system.
