How to query the objects in "Devices and Printers" into an array via PowerShell

Question

I'm having trouble trying to query the items that are in Devices and Printers. The long run goal is to delete everything located in 'HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Devices' except the devices located in Devices and Printers.

Unless there is another way to do this, I just need an array of the items in "Devices and Printers".

You can discover commands with Get-Command or gcm.

This should get you going...

C:\WINDOWS\system32> gcm *printer*
