Changing your default photo viewer to Windows Photo Viewer in Windows 10 allows you to enjoy a familiar, straightforward interface for viewing images, especially if you’ve recently upgraded from an older version of Windows or prefer its simplicity over the newer Photos app. This guide provides clear, step-by-step instructions to set Windows Photo Viewer as your default image viewer, along with troubleshooting tips and common pitfalls to avoid, ensuring a seamless experience. Before starting, ensure your Windows 10 system is up to date and that you have administrator privileges, as some steps may require elevated permissions.
What You’ll Need
- A Windows 10 PC with administrative access
- Images saved on your computer (JPEG, PNG, BMP, GIF, etc.)
- Optional: A registry editor or third-party tool if default methods do not work
Step-by-Step
- Open the Settings app by pressing Windows key + I on your keyboard.
- Click on “Apps” to access app-related settings.
- Select “Default apps” from the left sidebar.
- Scroll down to the “Photo viewer” section. You will see the current default app for viewing images.
- Click on the current default app (likely the Photos app). A list of available photo viewers will appear.
- From the list, select “Windows Photo Viewer.” If it’s not listed, proceed to the next steps involving registry edits.
- If Windows Photo Viewer does not appear, you need to enable it via registry editing. Press Windows key + R, type “regedit,” and press Enter.
- Navigate to HKEY_LOCAL_MACHINE\\SOFTWARE\
Microsoft\
Windows\
CurrentVersion\
Explorer\
FileExts\
.jpg (and other image file extensions like .png, .bmp, etc.) - Right-click on the extension key (e.g., .jpg), select “New” > “Key,” and name it “UserChoice” if it doesn’t exist.
- Within “UserChoice,” create a new string value named “Progid.”
- Set the value of “Progid” to “PhotoViewer.FileAssoc.Tiff” (for Windows Photo Viewer).
- Repeat this process for other image file types you want to open with Windows Photo Viewer (like .png, .bmp, etc.).
- Close the registry editor and restart your computer to apply changes.
- Now, when you double-click an image, it should open in Windows Photo Viewer by default.
- Test by opening an image file. If it opens in Windows Photo Viewer, you’ve successfully set it as your default.
Common Mistakes
- Not running the registry editor with administrator privileges, which can prevent changes from saving.
- Forgetting to restart the computer after editing the registry, which may prevent the system from recognizing the new defaults.
- Modifying the wrong registry keys or values, risking system instability or errors.
- Assuming that the “Default apps” setting will automatically list Windows Photo Viewer, which it often does not in Windows 10 without registry tweaks.
- Not backing up the registry before making changes, which can be risky if mistakes are made.
Tips
- Always back up your registry before making edits by exporting the current registry settings.
- If you’re uncomfortable editing the registry, consider using third-party tools like “FileTypeMan” or “Default Program Editor” that simplify this process.
- Keep your system updated, as some updates may affect how default apps are managed.
- Check for Windows updates if Windows Photo Viewer isn’t appearing or functioning correctly after changes.
- Create a system restore point before making registry modifications, so you can revert if something goes wrong.
Troubleshooting
- Windows Photo Viewer doesn’t appear in the default app list: Use registry editing to manually assign the file associations as described above.
- Images still open in Photos app after changes: Double-check the registry entries for the specific file types and ensure the “Progid” value is correctly set to “PhotoViewer.FileAssoc.Tiff.”
- After editing the registry, changes aren’t applied: Restart your computer or log out and back in. Clearing the icon cache can also help.
- Encountering errors during registry edits: Ensure you have administrator rights, and double-check the registry paths and values for typos.
- Windows updates revert your default app settings: You may need to reapply registry modifications after major updates.
