If you want to go back to the past (and some people do!) and you want Windows Photo Viewer back in Windows 10, then there is a little tweak you can do to make it work.
There is a simple registry edit that you need to make and that will make your images open in Windows Photo Viewer by default.
To do this, you can download the registry file from the link below:
Then double click it and run it on your machine. Then reboot your computer.
Next time you then open up an image file, you should now have the option to open it in Windows Photo Viewer!
