In my C:\TMP directory (which %TMP references) there is a copy of a desktop shortcut file (.LNK) to access control panel's "date and time" feature. This file is marked read-only, and the contents are inaccessible, both from TCC and from Windows Explorer. Changing to read-write does not work, neither from Windows Explorer nor from TCC. The condition has survived several system power off / restart cycles. How can I delete it? BTW, its presence prevents deleting the directory, too.
