Create One-Click Shutdown and Reboot Shortcuts in Windows.

First, create a shortcut on your desktop by right-clicking on 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” (without quotation marks). After you create the shortcut, double-clicking on 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,
eg : shutdown -r -t 01 -c “Rebooting your PC” Double-clicking on this shortcut will reboot your PC after a one-second delay and display the message “Rebooting your PC.”

Below mentioned are few switches and their functions..

• -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. The message must be enclosed in quotation marks.
• -f : Forces any running applications to shut down.
• -r : Reboots the PC.
