function Get-InstalledPrograms {

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

	Get-ItemProperty -Path @(

		'HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*',

	) -ErrorAction SilentlyContinue | Where-Object {

			$_.PSObject.Properties.Name -contains 'DisplayName' -and $_.DisplayName -like $DisplayName
		);
	} | Select-Object DisplayName, UninstallString, ModifyPath | Sort-Object -Property DisplayName;
