How to Change Your Screensaver in Windows 10
Windows 10 comes with several built-in screen savers. Why? In the dinosaur days of computing, computer monitors suffered from burn-in: permanent damage when an oft-used program burned its image onto the screen. To prevent burn-in, people installed a screen saver to jump in with a blank screen or moving lines. Today’s computer screens no longer suffer from burn-in problems, but people still use screen savers because they look cool.
To try one of Windows 10’s screen savers out, follow these steps:
Click in the Search box next to the Start menu, type Screen Saver and press Enter.
The Screen Saver Settings window appears.
Click the downward-pointing arrow in the Screen Saver box and select a screen saver.
After choosing a screen saver, click the Preview button for an audition. View as many candidates as you like before making a decision.
Be sure to click the Settings button because some screen savers offer options, letting you specify the speed of a photo slide show, for example.
If desired, add security by selecting the On Resume, Display Logon Screen check box.
This safeguard keeps people from sneaking into your computer while you’re fetching coffee. It makes Windows ask for a password after waking up from screen saver mode.
When you’re done setting up your screen saver, click OK.
Windows saves your changes.
If you really want to extend the life of your display (and save electricity), don’t bother with screen savers. Instead, put your computer to Sleep before stepping away: Right-click the Start button, click Shut Down or Sign Out, and choose Sleep from the pop-up menu. To wake your PC, tap any key on the keyboard.
