If you find that one or more of your icons are not displaying correctly, or that your icon cache is corrupted, you might want to consider rebuilding your icon cache.
To do so, Open Windows Explorer, and configure your Folder Options > Views to show Hidden / System Files. Next go to C:\Users\Owner\AppData\Local folder and delete the hidden IconCache.db file. Reboot. This action will purge and rebuild the icon cache.
There is also another way to do it, should the above method not work for you.
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.
