If you have Windows 10's default, Spotlight feature enabled, your lock screen shows gorgeous images courtesy of Microsoft. Some of these high-quality photos are nature shots while others are pictures of great cities around the world. The pictures rotate several times a day, but what if you see an image you like and want to keep a copy of it on your laptop? Windows keeps these Windows 10 lock screen photos buried deep in a hidden directory, but with a bit of digging, you can find them, save them and even use them as desktop wallpaper.
