This command lists shell folders. Use with the shell: command in Run dialog.

EG

shell:appsfolder@For /f "tokens=1* delims=" %%A in ('reg query HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions /f name /v name /s ^| findstr /c:"Name" ^| Sort') Do @Echo %%Apause

And gives output like

Finally list protocol handlers. This is how UWP apps are started. Also new control panel applets.
