Windows Shutdown Screens

Structure credit goes to Closing Logos Wiki. Thanks for doing all of this!

1st Screen

 * Screen: Simply, Windows exits and returns to DOS with no screen.
 * Sounds: None on Windows 1.0 - 3.0. A 4-note chime on Windows 3.1 versions.
 * Availability: Rare. It is only found on early Windows versions thru Windows 3.1. This was removed in Windows Codename Chicago.
 * Scare Factor: None, though you may be expecting a screen and then the PC shuts down.

2nd Screen

 * Screen: A dialogue box is seen saying "Please wait while system writes unsaved data to the disk". After that, due to the fact Windows did not support ACPI, another dialogue box is seen with a window with a moon behind it is seen saying "It is now safe to turn off your computer".
 * Sounds: The same 4-note chime on the Windows 3.1 versions.
 * Availability: Very rare. It is only found on Windows NT 3.1 - 3.51, and is updated to a Windows 95 style on Windows NT 4.0.
 * Scare Factor: None.
