Solve the problem of desktop icon exception under Win Vista

            I believe that many people have encountered the problem that the desktop icon is covered by the unknown program icon or the ugly black square. The question on the forum has been kept on the forum. In fact, this is caused by Vista's icon cache. Under normal circumstances, we have the following solutions: 1. Open the Vista optimization master - beautification master - remove the check & "quo; remove the shortcut small arrow" - save settings - logout (partially effective) 2. run regedit, Enter HKEY_CLASSES_ROOT\\lnkfile, delete the IsShortcut key value, and restart. If there is no such key value, you can create a new one, delete it and restart it. 3. Search or manually find the iconcache.db file under C:\\Users\\user name\\AppData\\Local and delete - restart
