  2. Save the file as photo.reg and 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.
