"Not Implemented" when clicking on photos in Windows Explorer

I send a big thank you to the author of this reply. He was the first to find the problem and provide a solution. I don't know why someone clicks "Likes" on replies that don't contribute much to the matter. Greetings to all.

I am having the same issue, just since the following Windows 10 update on Nov 1, 2024 ( a couple of days ago: 2024-10 Cummulative Update Preview.... Everytime I restart my computer, images from Explorer/all my files and folders, will open, but it is temporary each time. I also notice some updates with the Windows photos tool. So this must have been part of the update. This is obviously an update issue. Should I try to have Windows repair it or just uninstall the update? Hopefully a patch/updated update comes out quickly.

UPDATE 11/5/24: Found the issue, I think. The update just messed up the settings and removed it as the default app, leaving no app set. You need to readd Photos as the default. See screenshots...

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

Thanks, that worked for me too. In my case, also had to reboot after resetting the default to the Photos app.

That is pretty drastic as a first step ;)
