Use the Windows 10 Photos app to try to open the file and then download a HEIC plug-in from the Microsoft store

OR

Install CopyTrans HEIC for Windows. This tool adds full support for HEIC images to Windows. You’ll see thumbnails for HEIC files in File Explorer on Windows 10 (or Windows Explorer on Windows 7), and they’ll open in the standard Windows Photo Viewer. With this tool installed, you’ll also be able to insert HEIC files directly into Microsoft Office applications.
