One of my gripes with Windows Vista in the enterprise is that it simply says “Please Wait” during the startup and won’t tell you when it is trying to install managed software. Fortunately, this Group Policy change can resolve the issue:

Computer Configuration\Administrative Templates\System\Verbose vs normal status messages

Enable this setting and you are good to go. Sure, it’s so verbose it tells you when it is playing the logon sound, but in my mind, verbose is good.
