Windows 7 Photo Viewer was a favorite image viewing tool for many people. However, after upgrading to Windows 10, some users find that it no longer works as expected. This can be frustrating if you prefer the simplicity of the older viewer.

Fortunately, it is possible to restore Windows 7 Photo Viewer on Windows 10 with a few simple steps. These steps will help you get it running smoothly again.

This guide will walk you through the process carefully, from basic checks to more detailed fixes. You don’t need to be an expert to follow along.

Let’s get started and bring back your familiar photo viewer.

Quick Note Before You Begin

  • Check your Windows version: This guide is for Windows 10 users who want to use the Windows 7 Photo Viewer.
  • Back up important files: It’s always good to back up your photos before making changes to system settings.
  • Make sure you have administrator rights: Some steps require admin access to your computer.
  • Ensure Windows is updated: Sometimes a simple update can fix system glitches.

Step 1: Set Windows 7 Photo Viewer as Default Program

Windows 10 uses the Photos app by default, which replaces the Windows 7 Photo Viewer. To use the old viewer, you need to set it as the default program for image files.

  1. Right-click on any image file (like a .jpg or .png).
  2. Select Open with and then choose Choose another app.
  3. In the list, see if Windows Photo Viewer appears. If yes, click it.
  4. Check the box that says Always use this app to open .jpg files (or the file type you chose).
  5. Click OK.

Why this step matters: This tells Windows to use the old viewer every time you open photos instead of the new Photos app.

Step 2: Restore Windows 7 Photo Viewer via Registry File

If you don’t see Windows Photo Viewer in the list, it means it’s hidden in Windows 10. You can restore it by adding the necessary entries to the Windows Registry.

Important: Editing the registry can cause issues if done incorrectly. Follow carefully and consider backing up the registry before proceeding.

  1. Open Notepad.
  2. Copy and paste the following code into Notepad:
    3. Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows Photo ViewerCapabilitiesFileAssociations]
".jpg"="PhotoViewer.FileAssoc.Tiff"
".jpeg"="PhotoViewer.FileAssoc.Tiff"
".png"="PhotoViewer.FileAssoc.Tiff"
".bmp"="PhotoViewer.FileAssoc.Tiff"
".gif"="PhotoViewer.FileAssoc.Tiff"
  3. Save the file as RestorePhotoViewer.reg (make sure to select “All Files” under Save as type).
  4. Double-click the saved file and confirm the prompt to add the entries to the registry.
  5. Restart your computer.
  6. Try Step 1 again to set Windows Photo Viewer as the default program.

Why this step matters: This registry tweak re-enables the Windows 7 Photo Viewer options that Windows 10 disables by default.

Step 3: Use the Settings App to Choose Default Apps

Windows 10 allows you to set default apps through the Settings app as well. This is another way to assign Windows Photo Viewer if it is available.

  1. Press Windows + I to open the Settings app.
  2. Click Apps.
  3. On the left panel, choose Default apps.
  4. Scroll down to Photo viewer and click the current app (usually Photos).
  5. See if Windows Photo Viewer is listed and select it.

Why this step matters: This is a safer way to set defaults without manually editing the registry.

Alternative: Use Third-Party Image Viewers

If you are unable to restore Windows 7 Photo Viewer or prefer a more modern alternative, you can try free third-party image viewers such as:

  • IrfanView: Lightweight and supports many formats.
  • XnView: Simple interface and batch processing.
  • FastStone Image Viewer: Easy to use with basic editing features.

These programs can offer faster performance and additional features while maintaining simplicity.
