Over at the how-to-geek site they’ve shown a safe way to restart explorer on Vista. This is useful because it will close explorer “nicely” rather than terminating the process through the Task Manager.
- Open the Start menu.
- Hold down the Control and Shift keys, and right-click on a blank space in the Start menu.
- Choose “Exit Explorer.”
- Open the Task Manager (Ctrl+Shift+Esc), navigate to File->Run, enter “explorer” and hit OK.
