Create symlink from host:

{{$ touch file.txt
$ ln -s file.txt link.txt}}
Then delete link.txt in explorer on guest. This results in file.txt is deleted instead of link.txt.

Such a behavior is attributed to PathWalkthrough() which returns target file.

 
The task description is only applicable for Explorer. But there are some other interesting situations:

Executing erase /F deletes link (as it should be).

Executing rm returns cannot remove: Input/Output error
