@beliavsky  
My knowledge of Windows is quite limited but [NTFS](https://en.wikipedia.org/wiki/NTFS#Security) is a modern system which can deal with users and groups. I remember having been asked a password when trying to access the system directories on C:\ from the file explorer. Probably it would be the same thing if you try to navigate into those directories from CMD?

I have never tried WSL, and I don’t know if the sudo rights concern only the directories of the Linux system or also the whole Windows filesystem.

But note that even without `sudo`, on a Linux system you can cause great damages as you can delete all the user’s files!

And yes, looking for the strings you cited could be a good practice when using big codes, using for example `grep`:

```bash
$ grep -inRI EXECUTE_COMMAND_LINE

```

See also that discussion about the necessity to use `use, intrinsic ::`

Some scenarios are quite interesting like use iso\_c\_binding ! potentially exploitable use, intrinsic :: iso\_c\_binding ! safer The idea here is that one might inadvertently use a non-intrinsic iso\_c\_binding containing malicious code. Thanks @billlong for sharing the article.
