Most Windows computers are preconfigured to load a screen saver after a certain amount of idle time, usually 15 minutes. It is possible to have a password prompt displayed whenever the screen saver is interrupted by movement of the mouse or a key being pressed. This would require your usual password to be entered in order to resume using the computer. This is handy for laptops and PC's used in areas with a lot of people.
Here are the instructions:
- Right click an empty space on your desktop where there are no icons. This opens up a small menu.
- Select 'Properties' at the bottom of the menu. This opens the 'Display Properties' window.
- Click the 'Screen Saver' tab.
- Place a check in the box next to where it says 'On resume, password protect'
