A shortcut created by Cygwin or U/WIN has a special header format which is sort of uncommon. Additionally, the R/O attribute is set and maintained by Cygwin and U/WIN. When a user changes a shortcut s/he has to remove the R/O attribute first. If that attribute isn't set the shortcut is treated as a standard Explorer shortcut. If a user changes the content of the shortcut the header format changes since Explorer creates a completely different header. Even if the user sets back the R/O attribute the new header avoids that Cygwin uses the POSIX path in future and the shortcut is treated as all other Explorer shortcuts. They are treated as a symlink with only a DOS path pointing to the target.
