We may face the icon cache corruption issue sometimes in Windows 10 and earlier OS. The icon cache corruption causes the wrong icons to show up for certain programs or in certain areas of the Windows shell, or no icons at all. For example, your pinned taskbar shortcuts may show up with the wrong icon.
My earlier post Incorrect icon shown for a file type tells you how to refresh the shell icons using Default Apps. In some cases, the old icon may still show up after changing the file type association.
To render the icons for various shell objects like folders, special folders, and files, Windows caches the icons in database files so that Windows doesn’t have to read the file or folder icon and extract them every time. Occasionally, you’ll see icon-caching bugs in Windows resulting in incorrect, missing, or out-of-date icons being shown for programs and desktop shortcuts and other areas of the shell.
To resolve the incorrect icons issue, you may want to clear and rebuild the icon cache database completely. This post explains how to accomplish the task using different methods. The instructions apply to all versions of Windows, including Windows 10.
Clear and Rebuild the Icon Cache:
Before proceeding, try a simple fix like the ie4uinit.exe refresh method. In many situations, all that you need to do is refresh the icons without the need to clear and rebuild them.
If refreshing the icons using ie4uinit.exe or Default Apps doesn’t help, you’ll have to clear the icon cache completely.
How to Clear and Rebuild the Icon Cache in Windows
Let’s see how to clear the icon cache completely and let Windows rebuild it automatically.
Clear Icon Cache (ClearIconCache.exe) utility from Leo Davidson will cleanly exit Explorer, delete the shell icon cache (IconCache*.db), and localized thumbnail cache (ThumbCache*.db), and then restart Explorer.
Leo Davidson is a trusted source — he is the one who wrote the famous PDF x64 thumbnail & preview fix for Windows some years back. And he’s the owner of FileTypeDiag and many other useful portable tools.
With Clear Icon Cache, you double-click the program, and it takes care of the details for you. Clear Icon Cache works in Windows Vista, Windows 7, Windows 8, and Windows 10.
To run the utility in noninteractive or silent mode, run
As said earlier, the utility also clears the thumbnail caches on the computer.
The icon cache database files are located in your
%LocalAppData% folder with file names prefixed with
iconcache_ – each icon size has a separate cache (database) file.
The file names look like this:
iconcache_16.db iconcache_32.db iconcache_48.db iconcache_96.db iconcache_256.db iconcache_768.db iconcache_1280.db iconcache_1920.db iconcache_2560.db iconcache_exif.db iconcache_idx.db iconcache_sr.db iconcache_wide.db iconcache_wide_alternate.db
To clear the icon cache manually, follow these steps:
- Close all folder windows that are currently open.
- Launch Task Manager using the Ctrl + Shift + Esc key sequence.
- In the Task Manager Process tab, right-click on the Explorer.exe process and select End Process.
- Click the End process button when asked for confirmation.
- From the File menu of Task Manager, select New Task (Run…)
- Type CMD.EXE, and click OK
- In the Command Prompt window, type the commands one by one and press Enter after each command:
CD /d %userprofile%\AppData\Local DEL IconCache.db /a
- Additionally, in Windows 8 and Windows 10, the icon cache database is also stored in %userprofile%\AppData\Local\Microsoft\Windows\Explorer. To clear them, you must close all running applications, and run these commands in the Command Prompt.
CD %userprofile%\AppData\Local\Microsoft\Windows\Explorer DEL IconCache*.db /a EXIT
If you receive Access is Denied error when deleting the IconCache*.db files, then one or more of the open programs is using the icon cache database. Close all programs and try again, or try clearing them from Safe mode.
- In Task Manager, click File, select New Task (Run…)
- Type EXPLORER.EXE, and click OK.
Editor’s note: Instead of using Task Manager to exit Explorer.exe in Step 3 above, an even better way to do this is to terminate the Explorer.exe Shell cleanly using the method described in the article Terminate and Restart Explorer.exe Process Cleanly in Windows 7. If you’re using Windows 8 or Windows 10, check the article How to Exit Explorer and Restart Explorer in Windows 10.
This method uses a small script that I wrote to clean up the icon cache completely. Once done, the script restarts the Explorer shell for the change to take effect.

How to Use?
cleariconcache.vbsor create the VBScript file manually using Notepad.
- Save all your work and close all programs, so that icon cache files are not locked by any program.
- Double-click the script file
- Click Yes when you’re prompted to restart the shell.
Optionally, when the following dialog shows up, you can manually terminate the explorer shell gracefully (instead of the script doing it forcefully). See instructions for Windows 7 and Windows 10 to know how to quit the Explorer.exe shell process gracefully. Don’t restart a new explorer.exe process yet! Once done, click Yes.
If the Icon Cache database files can’t be deleted, some programs are using them. Close all applications and try rerunning the script.
It should be able to delete the icon cache files.
After clearing the cache, the Explorer shell should start automatically and rebuild a fresh set of icon cache.
I hope you were able to fix icon rendering issues on your Windows computer by clearing the icon cache completely.
