How to get Windows Photo Viewer back in Windows 10

Windows 10 ($160 at Amazon) has been around for years, but lots of people have only recently made the switch since Microsoft ended support for Windows 7 back in January (you can still download Windows 10 for free if you need to). If you were a Windows 7 or 8 holdout who just upgraded, you may have noticed that the Windows 10 Photo app is different from the old Windows Photo Viewer, and includes the ability to edit and enhance your images with a couple of clicks. 

Even with the upgraded features, some die-hard Windows Photo Viewer fans are finding their way back to their beloved original photo app. Here's how you can make Windows Photo Viewer the default photo app in Windows 10. 

If you upgraded from Windows 7, 8 or 8.1

It's easy to get the trusty old Windows Photo Viewer back -- simply open up Settings and go to System > Default apps. Under "Photo viewer," you should see your current default photo viewer (probably the new Photos app). Click this to see a list of options for a new default photo viewer. Assuming you upgraded to Windows 10 from a previous version of Windows, you should see Windows Photo Viewer as an option.

Choose Windows Photo Viewer and exit the Settings menu, and you're done -- photos will now open up in Windows Photo Viewer.

If you installed Windows 10 from scratch

This is trickier, because while Windows Photo Viewer is still technically available, it's not easy to find. It does involve editing the Windows Registry, which you should not attempt unless you know what you're doing -- editing the Registry can be dangerous if you make a mistake.

Here's how to do it:

2. Double-click on your new REG file to merge it with your Windows Registry. You will need to click through the User Account Control and a few other windows to allow the file to make changes to the Registry.

3. You should now be able to see the Windows Photo Viewer and set it as the default program for various image files. To do this, open the Control Panel and go to Default Programs > Set Default Programs. Find Windows Photo Viewer in the list of programs, click it, and choose Set this program as default. This will set the Windows Photo Viewer as the default program for all file types it can open by default.
