'', 'Wow6432Node\' |
	ForEach-Object {Get-ItemProperty -Path HKLM:\SOFTWARE\$($_)Microsoft\Windows\CurrentVersion\Uninstall\* |
	Where-Object {($_.DisplayName -like '*Java *') -and (-not $_.SystemComponent)} |
	Select-Object DisplayName, DisplayVersion, InstallLocation, @{n='Architecture'; e={If ($_.PSParentPath -like '*Wow6432Node*') {'x86'} Else {'x64'}}}}
