Using W10 21H2.
Start menu shortcuts are usually located in two folders:
%AppData%\Microsoft\Windows\Start Menu\Programs
%ProgramData%\Microsoft\Windows\Start Menu\Programs
So customizing the Start menu is usually a matter of organizing the content of these folders. However there are entries in the Start menu without shortcuts at these places:
Examples:
These shortcuts are from MS (green) and also from the computer manufacturer (magenta). The lack of shortcuts prevent me to customize the Start menu the usual way.
Any suggestion about where to find the missing shortcuts?
