Photos app is the default picture viewer in Windows 10. The Photos app has all the features from classic Windows Photo Viewer plus image editing capabilities. The Photos app can even import photos from phone and camera.
While viewing a picture file in the Photos app, you may want to zoom in or zoom out the picture. With default settings, you can zoom in and out by holding down the Ctrl key and then rotating the mouse wheel.
Rotating the mouse wheel without holding the Ctrl key brings up the next or previous image. That is, you can switch to the next or previous picture by rotating the mouse wheel.
Many users have asked us if it’s possible to configure Windows 10 zoom in and zoom out using the mouse wheel without holding the Ctrl key. Because we can always switch to the next or previous image by pressing arrow keys on the keyboard, it makes sense to configure the Photos app to zoom in and out photos when you rotate the mouse wheel.
Luckily, an option in Photos app settings allows us to configure the mouse wheel action for the Photos app. Using this option, you can zoom in and zoom out in the Photos app simply by rotating the mouse wheel (without using the Ctrl key).
Use mouse wheel to zoom in and zoom out in Photos app
Here is how to configure the Photos app to zoom in and zoom out pictures using only the mouse wheel (without having to hold down the Ctrl key).
Step 1: Open the Photos app using the Start/taskbar search.
Step 2: Once the Photos app is launched, click the three dots icon (located just below the close button) and then click Settings option. This will open Photos app settings page.
Step 3: Finally, in the Viewing and Editing section, you can find mouse wheel settings. Select Zoom in and out option. That’s all!
From now onwards, you can always rotate the mouse wheel to zoom in and zoom out images in the Photos app.
