MKLINK cannot be used to delete symbolic links. To remove a symbolic link, simply delete them as if you’re removing a normal file. For example, to delete the foo symbolic link created above, enter the following command:
If the link is a hard link to a directory:
C:\test>rmdir foo
OR ELSE, IF the link points to a FILE (as opposed to a dir)
C:\test>del foo
