No, some people actually know how Windows works. The kernel has very little to
do with .lnk files, and in fact it sees them as regular files. If you run
"notepad foo.lnk", you will see the link's binary contents. If you use the
CreateFile or OpenFile kernel calls, you will get a file handle pointing to
the link's contents. If you attempt to execute a .lnk file from the command
line or using CreateProcess, it will horribly fail.

In fact, to dereference a link in userspace, you must open the .lnk file,
examine its contents with a library call, and then open the destination file.
This is extremely similar to how Gnome or KDE handle .desktop files: mainly
in the shell.
