CodeJacked have a nice tip for Windows users to re-start Windows without re-starting their Vista or XP powered PCs.

The trick is to hold down the SHIFT key when invoking the restart.

Windows Vista: Select Start, then hover over the right arrow that is to the right of the padlock icon until the pop-up menu appears that contains “restart” as one of it’s choices. Hold down the SHIFT key while clicking on the “restart” choice.

Windows XP: Select Start. Select “Shut Down…”. Change the drop-down combo box under “What do you want the computer to do?” to “Restart”. Hold down the SHIFT key while clicking on the “OK” button.
