Here is a free and open-source tool to write a raw disk image file to a removable device (say USB or flash drive). The tool is named Win32 Disk Imager.

I want to use that standard file open dialog box. Any links to info on it? The nearest I could find was "CreateFile" Thanks.

A bunch of new files were quietly added to the Windows 11 System32 folder and they seem to suggest Microsoft may be looking to ditch UWP in favor of XAML and Win32-based shell on Windows 11.
