"So completely"? It at least executes them, and it does offer you to turn
them aliases on and off (see
Granted, the user interface has a lot of room for improvement, but if you
are dead set on finding out what, say, that `idle.exe` app execution alias
refers to, you can go to `Settings>Apps>Apps & features>App execution
aliases` and find out that it is owned by the Python 3.7 package. That
does not give you the path, but it does give you way more information than

The `fsutil` program, contrary to your claim, is available without WSL:
And yes, for under-documented reparse points, the tool gives you only a
