All icons show the same picture

All icons show the same picture, or icons are all broken on desktop/taskbar, wherever. I’ve encountered it twice this week, once notepad was shown, the other time was Word.

1. Kill Explorer
2. Open the command prompt
go to: %USERPROFILE%\AppData\Local
3. Unhide the IconCache.db file with the following command: attrib -h IconCache.db
4. Delete the IconCache.db file: del IconCache.db
5. Start Explorer
Cross Fingers.
