the problem was that I was manually deleted IsShortcut from HKEY_CLASSES_ROOT/lnkfile
I have a .reg file that repair all shortcuts..
i hate the arrow on shortcuts and in XP there is no problem to del it, but in windows 7.... who knows
hope to help to somebody with the atteched file ;]
Thanks a lot, and happy new year for everyone!
