Fix: You installed the wrong extension. Uninstall "HEVC Video Extensions" and ensure you have "HEIF Image Extensions" installed. Restart your PC.
After installation, the default Photos app, File Explorer thumbnails, and other Windows apps will open HEIC files.
⚠️ Some users need the "HEVC Video Extensions" (usually $0.99) if the free version doesn't work. An alternative is the "HEIC to JPEG" converter app on the Store.
The most integrated solution involves installing two specific extensions from the Microsoft Store.

Yes:
Microsoft has made viewing HEIC images on Windows 11 much easier than in the Windows 7 days, but it still requires a manual setup. The ecosystem is fragmented: Apple pushes HEIC for efficiency, Microsoft pushes JPEG for compatibility.
Your best bet is to install the free HEIF Image Extensions immediately upon setting up a new Windows 11 PC. If you find the official Photos app too slow, switch to IrfanView for raw speed. And if you are tired of the format war altogether, change your iPhone settings to shoot in JPEG.
One thing is certain: You never need to throw away a photo because you can't open it. With the tools above, you now have a complete HEIC viewing solution for Windows 11 that rivals any Mac.
Windows 11 does not always open HEIC files natively on every device. Installing support enables thumbnails, File Explorer previews, and reliable viewing/editing in apps like Photos, Paint.NET, and Photoshop.
