Shortcut Properties

I found this code on this site and it works.

$shell = New-Object -ComObject WScript.Shell

$Location = "C:\ProgramData\Microsoft\Windows\Start Menu\Programs"

$shortcut = $shell.CreateShortcut("$Location\clickme.lnk")

$shortcut.TargetPath = "notepad.exe"

$shortcut.IconLocation = "shell32.dll,2"

$shortcut.Save()

But I need to add a value for the START IN property.  I've tired

$shortcut.Start = "C:\Windows"

$shortcut.StartIn = "C:\Windows"

And the shortcut does get created but the START IN is left blank.
