Fixing the 'Not Implemented' Error When Opening Photos on Windows 10/11

Below is an in-depth article addressing the “Not Implemented” error encountered when opening photos on Windows 11 or 10. The piece covers a range of potential causes—from corrupt system image files to conflicting background applications—and provides step-by-step solutions to help users troubleshoot and resolve the issue.

Understanding the Error​

When faced with the “Not Implemented” error while attempting to open photos, many Windows users find themselves stumped. The error message may seem cryptic, but it typically points to underlying problems with system files, background applications, or even Windows updates.
This error could be compared to stumbling upon a roadblock when your normally reliable navigation system suddenly fails. The connection between corrupt system files or conflicting applications can derail even the simplest task of opening an image. This article will guide you through the essential troubleshooting steps to restore seamless photo viewing on your Windows device.

Identifying Potential Causes​

Before diving into the solutions, it’s important to understand what might trigger the error:

• Corrupt System Image Files: Damage or corruption in core Windows components can interfere with system processes.
• Conflicting Background Applications: Third-party software running in the background might conflict with the Photos app.
• Recent Windows Updates: Although designed to enhance functionality, some updates may inadvertently introduce issues.
• Incorrect Default App Settings: Misconfigured default programs for image file types might cause the system to behave unexpectedly.
• Issues with User Profiles: Sometimes, a corrupted user profile rather than the system itself is to blame.

With these possibilities in mind, let’s explore the respective fixes.

Step-by-Step Troubleshooting & Solutions​

1. Restart Windows Explorer​

An immediate and simple fix that often resolves temporary glitches is to restart Windows Explorer:

• Open the Task Manager by pressing Ctrl+Shift+Esc.
• Scroll down to locate Windows Explorer under the Processes tab.
• Right-click on Windows Explorer and select Restart.

This quick move refreshes the graphical shell and can resolve transient issues blocking the opening of photos.

2. Repair Your System Image Files​

Corrupt system files can be the root cause of the “Not Implemented” error. Using built-in tools such as System File Checker (SFC) and Deployment Image Servicing and Management (DISM) is essential:

• System File Checker (SFC):
  Run the command prompt as administrator and type:
• sfc /scannow
  This command will check and automatically repair corrupted system files.
• DISM Tool:
  For deeper-level repairs if the SFC tool does not resolve all issues:
• Open Command Prompt as an administrator and run:
• DISM /Online /Cleanup-Image /RestoreHealth
  This process might take some time, so patience is key.

Both tools work in tandem to restore the integrity of Windows image files.

3. Check the Issue in a Clean Boot State​

Sometimes, background services or third-party applications can interfere with the Photos app. Booting Windows in a Clean Boot state helps identify such conflicts:

• Steps to enter Clean Boot:
• Open System Configuration (msconfig.exe).
• On the General tab, select “Selective startup” and uncheck “Load startup items.”
• Navigate to the Services tab, check “Hide all Microsoft services,” and then click “Disable all.”
• Restart your computer.

Once in Clean Boot, try opening a photo. If the error no longer appears, re-enable services selectively to pinpoint the conflicting application or service. This methodical enabling and testing helps narrow down the culprit.

4. Uninstall Recently Installed Windows Updates​

Although Windows updates are crucial for security and performance, sometimes an update can introduce unexpected errors. If you suspect a recent update:

• Access the Settings app.
• Navigate to Update & Security > Windows Update > View update history.
• Identify recent updates around when the error started.
• Use the “Uninstall updates” option to remove the update and test if the error resolves.

Keep in mind that uninstalling updates should be considered a temporary workaround while a permanent fix is awaited through further updates or patches.

5. Verify and Set Default App Settings Correctly​

Windows 11’s default apps feature allows you to designate which application opens specific file types. A misconfigured default might cause the error. To fix this:

• Open Windows Settings and go to Apps > Default apps.
• Scroll until you find the Photos option.
• Check and, if necessary, reassign the default app for common image file extensions such as .jpg, .png, and others.

Ensuring the correct application is set as the default can resolve unexpected behavior when opening images.

6. Switch to the Photos Legacy App​

For some users, switching to the Photos Legacy app provides a viable workaround. Here’s how to proceed:

• Launch the Photos app.
• Click on the gear-shaped icon at the top right to access Settings.
• Scroll down and click on Get Photos Legacy. This action will redirect you to the Microsoft Store where you can install the app.
• After installation, right-click on an image file and select Open with > Photos Legacy.
• If this solves the problem, set Photos Legacy as your default image viewer.

Switching to an alternative preview app often sidesteps the issues inherent in the primary app.

7. Create a New User Profile​

Sometimes the error is not due to the system at large but is isolated to a particular user profile. Creating a new user profile can help determine if your current profile is the source of the issues:

• Create a new local user account via Settings > Accounts > Family & other users.
• Assign administrative privileges if needed.
• Log out of your current account and sign in with the new profile.
• Attempt to open a photo.

If the error does not occur in the new profile, consider migrating your data and using the new account as your primary profile.

8. Repair or Reset the Photos App​

If the Photos app itself is malfunctioning, using the repair or reset options might bring it back to life:

• Open Windows Settings and head to Apps > Installed Apps.
• Locate the Photos app from the list.
• Click on the three dots and select Advanced Options.
• Scroll down and choose Repair. If repair does not remedy the problem, opt for Reset.

This process reinstates the app’s default configuration and addresses potential software glitches.

9. Restore Your System​

As a final measure, if none of the above solutions work, consider restoring your system to a previous state when it functioned correctly:

• Type “System Restore” in the Start menu.
• Follow the on-screen instructions to choose a restore point.
• Confirm the restoration and allow the process to complete.

A system restore can be especially useful if the error emerged after a recent update or software installation that disturbed the system’s stability.
