- [X] WSL 2

### Other Software

File Explorer

### Repro Steps

1. Install WSL 2
2. Try to open `\\wsl.localhost\Ubuntu\mnt\c` from File Explorer

### Expected Behavior

File Explorer should allow to open such mounted disk.

### Actual Behavior

File Explorer returns a permission denied when trying to open the `\\wsl.localhost\Ubuntu\mnt\c` directory.

### Diagnostic Logs

_No response_

Start by reproducing the reported WSL 2 scenario on Ubuntu 22.04: open \\wsl.localhost\Ubuntu\mnt\c from File Explorer and confirm the permission-denied result. Investigate the WSL mount and File Explorer interaction; done means the mounted path opens successfully without permission errors and diagnostic evidence is available.
