How do you make Windows XP show It is now safe to turn off your computer when you shut down?
Windows XP does not normally do this on modern computers. The message was only used on older computers that used an AT power supply and thus had to be physically switched off. For this to show up on a modern computer, you would need to disable ACPI (Advanced Configuration and Power Interface) and APM (Advanced Power Management) and reinstall Windows XP or replace its HAL driver in the Device Manager.Note that disabling ACPI can make some hardware drivers not work correctly and make your computer use more electricity; it's generally not recommended that you do this.
