#     Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall | Get-ItemProperty | Where-Object { $_.DisplayName -match "Printer" } | Select-Object DisplayName, PSChildName | Sort-Object DisplayName | Out-GridView
