Like many Windows users, I’ve set up a slide show of favorite images for my desktop background. But most of those images don’t precisely match the screen resolution, so they’re often oddly cropped.
Depending on the setting you use, they might also be stretched or have black bands around them. It’s one of those small but persistent annoyances. Surprisingly, a simple solution can be found in Win10’s included Photos app.
Photos is far from a comprehensive image-editing tool, but it does have a little-known option that lets you quickly crop images to match your screen’s aspect ratio — so your images appear as you want them to.
Here’s how: Launch Photos and select the image you want to edit. (The first time you launch the app, it’ll try to locate all images on your system — a process that might take some time, depending on the number of photos you have.) Next, select the pencil icon to open Photo’s editing tools.
On the right side of the Photos window, click the Crop tool. That’ll display a cropping box within your photo. Now select the Aspect ratio tool (a box-shaped icon), located on the upper-right side of the Photos window. Among the drop-down options is Lock screen (see Figure 1). Select it; you can then change the cropping box to your liking, and the aspect ratio will remain the same.
Click the checkmark icon to apply the change. You can then either save the image or save a copy via the “floppy disk” icons.
Oddly, using the “copy” option doesn’t let you give the file a new name or save it to another location; it simply adds a (2) to the end of the original name.
