Windows Spotlight is a new feature in Windows 10 that affects your lock screen -- it's basically Bing's homepage images, but on your lock screen. The photos cycle periodically, so it's sort of like a curated slideshow of beautiful, high-resolution images on your lock screen. Oh, and Windows also lets you provide feedback about each image for a more personalized experience.
Here's how to turn on this cool feature so you can see new, awesome photos each time you unlock your device:
1. Open up the Settings menu and go to Personalization > Lock screen.
2. Under Background, click the drop down menu and choose Windows spotlight. Exit out of the Settings menu to confirm your changes.
3. The next time you unlock your device, your lock screen will have a brand-new, high-res image pulled from Bing. In the upper right corner, you should see a small box that says Like what you see? Roll over this box and choose I like it or Not a fan to give Windows some feedback on how you feel about the image. Windows will use your feedback to tailor lock screen images to your personal taste in the future.
