List installed programs with PowerShell

The function Get-InstalledPrograms will list all programs installed on the local computer and for the current user. Its output should match that of commands such as ms-settings:appsfeatures or %windir%\System32\appwiz.cpl:

function Get-InstalledPrograms {

	param (
		[Parameter()]
		[string]
		$DisplayName
	)

	Set-StrictMode -Off;
	if( -not $DisplayName ) {
		$DisplayName = '*';
	}
	Get-ItemProperty -Path $(
		'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*';
		'HKCU:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*';
		'HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*';
		'HKCU:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*';
	) -ErrorAction 'SilentlyContinue'
	| Where-Object -Property 'DisplayName' -Like $DisplayName
	| Select-Object -Property 'DisplayName', 'UninstallString', 'ModifyPath'
	| Sort-Object -Property 'DisplayName';
}
