Windows 11 fichier explorer no longer shows thumbnails for PNG images

[ForumBot]

Thumbnails for `.jpg`, `.webp`, `.mp4`, and other fichier formats seem to work just fine, c'est seulement `.png` fichiers that ne work.

Things I've tried:

- Removing my thumbnail cache using the disk cleanup utility

- Toggling "Toujours show icônes, jamais thumbnails" on and ensuite off again in Explorateur de fichiers Options

- Changing the par défaut `.png` app from Photos to a different app, ensuite back to Photos (that en fait made the problème worse, parce que maintenant windows is assigning the fichiers this ugly blurry par défaut icône à la place du Photos app icône)

- Restarting my ordinateur

- Making sure Windows is up to date

- Making sure my graphics pilote is up to date

- (From [this thread](https://answers.microsoft.com/en-us/windows/forum/all/png-thumbnails-not-showing/51adc66a-37a9-4ba2-833b-594efedbd040))

Appuyez sur Windows clé + R

Type: ie4uinit.exe -show

Hit Enter

- Restarting my graphics pilote avec `Windows key + Ctrl + Shift + B`

- From `C:\Users\(user)\AppData\Local\Microsoft\Windows\Explorer`, supprimer all `thumbcache` and `iconcache` fichiers

- Ran `DISM /Online /Cleanup-Image /ScanHealth`, which showed "No component store corruption detected. The operation completed successfully."

- In Windows Paramètres > Apps > Apps & Features > Microsoft Photos > Advanced options, I clicked Reset, ensuite rebooted again.

Yet encore, not a single `.png` fichier sur mon ordinateur shows a proper thumbnail anymore. See capture d'écran.

Comment puis-je get my `.png` thumbnails back?

Il semble que [other users on the Microsoft forums are having this issue](https://answers.microsoft.com/en-us/windows/forum/all/png-thumbnails-not-showing/51adc66a-37a9-4ba2-833b-594efedbd040) as of this week:

J'ai the exact same problème. It started a couple days ago out du blue. J'ai essayé all the steps listed but c'est encore happening. J'ai vu this sort of thing on other forums and there ne seem to be a fix other than to re-load windows which is a pain for a sysadmin avec tools to reinstall and re-configurer. Maybe the next mise à jour will fix it....but dans le meantime, I'll just guess entre the txt fichiers and the png fichiers sur mon desktop....
