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)
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 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....
