How To Change Logon Screen Background Color (not Wallpaper)

but today I am stumped.In Windows XP, there was an option to change the logon screen background color:HKEY_USERS.DEFAULTControl PanelColorsYou could change the string "Background" to any 3-digit RGB color code you wanted.(i.e., 0 0 0 = black, etc.)This color would show up on CTRL+ALT+DEL plus it would show up when you logged in remotely using Remote Desktop.Changing the logon screen background wallpaper is great when you're physically at the machine (and I've already done this), but you don't see it when you're connecting via Remote Desktop. Instead you're stuck with the OEM blue background color.The same key I mentioned above does in fact exist in Windows 7, but it doesn't appear to have any effect.
