"Not Implemented" when clicking on photos in Windows Explorer

Hello Danielnrg,

Welcome to Microsoft Community.

Based on your situation, it is recommended that you perform a system repair first. You can refer to the following information for specific steps:

Check system file integrity and run DISM:

Search for CMD, find Command Prompt, and run it as administrator.

Enter the following commands one by one, making sure to execute each command completely before moving on to the next:

sfc /scannow

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth

Once the scans are complete, you can check the scan information to see if any issues were detected and repaired.

Disclaimer: At this point, we have exhausted all troubleshooting and I recommend that we try to perform a clean install to get your computer back into a working condition. Please ensure that you backup any important data, including Documents, Pictures, Videos, and more. After that, you can find instructions on how to install Windows 10/11 in the following article by MVP Andre: How to: Perform a Custom Installation of Windows 11 and Windows 10 - Microsoft Community 

To rule out other factors, please try the following steps to see if the issue persists:

Perform a clean boot:

1. Press Windows+R, type "msconfig", and press Enter to open System Configuration.
2. Go to the Services tab, check "Hide all Microsoft services", and then click "Disable all". (If you have fingerprint recognition enabled, do not disable the related services.)
3. Click the "Startup" tab, click "Open Task Manager", and then disable all startup items.
4. Restart your device.

Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.  

These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by step so that it will help you get back on track.

If the issue persists, please provide your specific system version information.

I hope this information is helpful to you.

If you have any questions or concerns, please feel free to let me know.

Best wishes

This just started happening to me too. It seems to be an update that was installed that is causing the issue. This has worked fine for years...literally 5 or 6 years I have been using this computer, then all of a sudden this starts happening. There are 22 people with the same question and we have all been searching in the last 24 hours. Obviously something changed very recently during an update. Reinstalling the OS is not an option.

Here is something interesting, if I move the jpg file to my desktop and double click on it it opens just fine, but from any other folder it fails.

EDIT: All the checks ended with "No component store corruption detected." and "The restore operation completed successfully." No change in the ability to double click on a jpg file and have it open in Photos.

I just started having the same problem today. Restarting worked for a bit, now it's back to the same problem. I have not tried any fixes listed yet.

I will try clean boot, the only thing is I would have to stay in clean boot for around 24 hours since a restart would temporarily fix the issue.
