With Photo Gallery you can undo changes you make to your photos so they look like they did when you first imported them. When you edit a photo, the original photo isn't visible in the gallery. To see both the original and edited versions of your photo, you'll need to make a copy of the original photo before you edit it.
If you have difficulty finding your edited photos, see Find recently edited photos in Photo Gallery.
Select the photo or photos that you want to remove changes from and on the Edit tab, click Revert to original.
Double-click the photo you want to make a copy of to open it.
On the Edit tab, in the Manage group, click Make a copy.
Name the copy of the photo and click Save. The copy you just made will appear in the gallery.
