Really useful tip! Thanks.

There is also another way to do it, should the above method not work for someone.

Kill Explorer.exe process. To do so, click Start button > Hold down Ctrl+Shift & Right Click on empty area in the Start Menu > Click "Exit Explorer".

Click Ctrl+Shift+Esc keys and open Task Manager.

Click File > New Task > cmd.exe > OK. This will open the command prompt.

Type cd /d %userprofile%\AppData\Local
Click OK
Type attrib –h IconCache.db
Click OK
Type del IconCache.db
Click OK
Type start explorer
Click OK.

Your Vista Icon Cache would have been rebuilt.
