### Repro Steps

1. Install a fresh Debian instance:
```
wsl --install -d debian
```
2. Create default user (its name does not matter, let's take `admin`).
3. From WSL terminal, open Windows Notepad as `root`:
```
sudo -u root $(command -v notepad.exe)
```
4. Within Notepad GUI, type some random text and save it to a new file (for example, `test.txt`) located at `\\wsl$\debian\home\admin\`.
5. Close the Notepad window.
6. Again from WSL terminal, check the owner of the newly-created file:
```
$ ls -l ~/test.txt
```

### Expected Behavior

```
-rw-r--r-- 1 root root 9 Sep 4 19:52 /home/admin/test.txt
```

### Actual Behavior

```
-rw-r--r-- 1 admin admin 9 Sep 4 19:52 /home/admin/test.txt
```

### Diagnostic Logs

_No response_

Start by reproducing the WSL 2 Debian scenario with `sudo -u root $(command -v notepad.exe)` and the `\\wsl$\debian\home\admin\` path. Investigate how native Windows executables launched from WSL handle file ownership; done means the reproduced file ownership matches the expected root-owned result.
