Personally, I would do a clean Vista installation (versus upgrade). The
fact that your file associations are getting corrupted in such an unusual
way, by something (?), needs investigation. Just a theory: did you use some
tweak to remove the arrow shortcut overlay?
In the interim, a possible quick fix would be to copy the following (between
the dashes) into Notepad, and save as link.reg (no .txt extension):

Double-click on link.reg, and allow the merge. On the other hand, you could
just check each of the above keys and values against your registry entries
