If you want an app to display while your screen is locked, you can click on one of the plus signs to add it. The other lock screen settings on this page are mainly used to customize what apps display data on your home screen. Basically, it’s an automatic version of the slideshow option that doesn’t require you to set a folder. It downloads and rotates through a selection of backgrounds from Microsoft. The last two work exactly the same as the desktop background does, but “Windows spotlight” is a little different. There are a few slightly different options here, but there are three main options on the top drop down menu: “Windows spotlight,” “Picture,” and “Slideshow.” Once you’ve chosen your desktop background, you have another choice to make: what do you want your lock screen to look like? You can click on “lock screen” in the dark gray bar at the left to move to that group of settings too. “Solid color” allows you to choose a solid color instead of a background picture if you want to keep it really simple. It defaults to your Pictures folder, but you can choose something else if you have photos saved elsewhere.

“Slideshow” allows you to select a folder and change the background periodically to a new photo from that folder. This is great for taking, say, a family photo that you saved to a USB drive and making it into a desktop background. Windows comes with quite a few pictures that can be chosen directly from this panel, but if you want to use a different one, you can use the “Browse” button on the page to find your chosen photo. Play around with these to see how they each look with your photo. There’s a drop-down box under this panel that asks how you want the photo to be displayed, and each setting does something different. “Picture” is exactly what it sounds like: a picture. There are three options you can choose from the first drop down box here. You’re not going to see much that’s changed here. If you’ve used Windows before, it’s pretty similar to previous versions. “Background” allows you to change the background of your desktop, giving you a different look.
