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 rebuild the Icon Cache. The Icon Cache or IconCache.db is a special database file that Windows utilizes to keep copies of each icon handy. When Windows needs to draw an icon, it uses the copy from the cache instead of retrieving the icon image from the original application file. This helps in making Windows draw the icons faster.
Rebuild The Icon Cache:
In Windows 10, 8 and Windows 7, this IconCache.db file is located at:
- C:\Users\<user profile>\appdata\local
If you find your Windows displaying icons on the desktop in the wrong manner you can purge & rebuild the Icon Cache In Windows.
If you need to rebuild the Icon cache, Open File Explorer > Folder Options > Views to show Hidden System Files. Next, go to C:\Users\Username\AppData\Local folder and delete the hidden IconCache.db file. Reboot. This action will purge and rebuild the icon cache.
