Shutdown and Reboot in Style ☺

Turning off or rebooting XP involves a several-step process: click the Start menu, choose Shut Down, and then select Shut Down or Restart. If you want, however, you can exit or reboot much more quickly, by creating a shortcut that enables one-click shutdowns. You can also use the shortcut to customize the shutdown or reboot for example, by displaying a specific message or automatically shutting down any programs that are running.


First, create a shortcut on your desktop by right-clicking the desktop, choosing New, and then choosing Shortcut. The Create Shortcut Wizard appears. In the box asking for the location of the shortcut, type shutdown. After you create the shortcut, doubleclicking it will shut down your PC. But you can do much more with a shutdown shortcut than merely shut down your PC.
You can add any combination of several switches to do extra duty, like this:


shutdown -r -t 01 -c "Rebooting your PC"


Double-clicking that shortcut will reboot your PC after a one-second delay and display the message "Rebooting your PC." The shutdown command includes a variety of switches you can use to customize it. 
Switches you can use with shutdown             Switch What it does
-s                                                                      Shuts down the PC.
-l                                                                        Logs off the current user.
-t nn                          Indicates the duration of delay, in seconds, before performing the action.
-c            "messagetext" Displays a message in the System Shutdown window. A maximum
of 127 characters can be used. The message must be enclosed in quotation marks.


-f                         Forces any running applications to shut down.
-r                         Reboots the PC.


Here are the ones I use for shutdowns and restarts:


Shutdown -s -t 03 -c "See you later!"


shutdown -r -t 03 -c "You can't get rid of me that quickly!"


You always have to turn from the CPU after running this command. (Same with AT and ATX powered machines.) If you want to turn down power of ATX machine automatically, run the following commnd "c:\windows\system32\tsshutdn.exe 00 / POWERDOWN / DELAY:00" This is used to turn off a server. Even though you don't have networked computers attached to your computer, this works.
