How to Rebuild Icon Cache on Windows 10

After the release of the first version of Windows, the Microsoft operating system has been using icons to identify your programs and the files they open. The graphical user interface offers a quick way to identify your files and which application opens them. Sometimes, however, your icons might appear blank or corrupt, or display the wrong icons. For example, your word files might not show the icon that identifies them as a Microsoft word file, or your computer game launcher might be missing its icon. Blank thumbnails might also occur in similar situations. In less severe cases, you icons might take too long to load. This article will explain why your file icons might be missing and how you can retrieve them.

How the icon cache works

Icons are everywhere in Windows: the Control Panel, Programs and Features, File Explorer among others. In order to render your file icons, Windows stores all icons in an icon cache database. This 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 rather than retrieving the icon image from the original application file. This is what allows the icons to be rendered faster because it will not need to reload the icons every time.

In Windows Vista and Windows 7, the icon cache file is located in: C:\Users\<your username>\AppData\Local\IconCache.db. While this file is still present in Windows 8 and 10, these versions of Windows do not use them to store the icon cache. Instead, Windows 8 and Windows 10, stores the icon cache files in the C:\Users\<your username>\AppData\Local\Microsoft\Windows\Explorer folder location. Here you will find several icon databases that cache your icons.

Why your files are missing icons in file explorer

The database file grows as more information is added to it. Windows checks for an icon against this database, and if an icon is found, it will be displayed; otherwise your executable file is checked for an icon instead.

Sometimes the icon cache database might get out of date, causing icons to display incorrectly, or even go missing. If the icons in this database are corrupt, then your file icons and thumbnails will not be displayed correctly either. This can also happen after upgrading an application where the new version came with a new icon, but you still see the old icon on the desktop or a blank icon. It is also possible that an application (e.g. an icon changing application) is taking control of what icons are displayed from your registry.

When this happens, you have to reset the icon cache and let Windows automatically re-create it. This is how you can do it.

Delete icon cache using a batch or executable file

You can create a batch file that will automate rebuilding of your icon cache. We have added prompts to this batch file to avoid mistakes. Here is how you can create the batch file on your PC and use it.

  1. Click here to download the batch script to repair icon cache.
  2. One the file has been downloaded, right click and choose run as administrator.
  3. Follow the prompts on the command prompt window.

If your icons don’t rebuild automatically, you might need to restart your PC. If the icons are still not displaying properly after rebuilding the icon cache, then download and merge the .reg file for the .ico (ICO) option here to restore the default associations of .ico (icon) files in Windows 10.
