On Windows 10 (and 11), the screen saver used to be one of those features you had to configure on your device to protect those big cathode ray tube (CRT) monitors against burn-in as a result of rendering the same image for an extended period. After the CRTs, the LCD displays came along with new technologies that made monitors more resistant to burn-in while offering superior image quality, turning screen savers into a thing of the past.
Although it's no longer required to use this feature, if you happen to be using a display susceptible to burn-in, such as an OLED, plasma, or CRT, or you want to create a different look and feel when you're not actively using your computer, you can still configure screen savers on Windows 10. You just need to know where to find the settings.
