Rebuild Icon Cache in Windows 11/10
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. Things were different in Windows XP, and they are different in Windows 7/8. Things changed again from Windows 8.1 onwards. In Windows 11/10, you need to do the following. If you needed to rebuild the Icon Cache in Windows 7/8, you needed to do the following:

If you were to be able to delete some of them, you would now be able to see a new folder created named IconcacheToDelete, which will disappear when you reboot your computer or restart Windows File Explorer.

Clear Thumbnail cache in Windows 11/10
Windows Thumbnail cache or Thumbs.db files are hidden data-files in the Windows operating system, which contain small images, displayed when you view a folder in “thumbnail” view, as opposed to tile, icon, list, or detail view. Windows keeps a copy of all your pictures, video and document thumbnails so that they can be displayed quickly when you open a folder. In Windows XP you see these ‘hidden’ files thumbs.db files scattered all over the place. In Windows Vista and later, the thumbnails ‘thumbcache’ are stored at C:\Users\Owner\AppData\Local\Microsoft Windows\Explorer – which is the same where the icon cache files are stored.
