Personalization Change Icon Cache Size in Windows 11

  • Staff
configuration_banner.png

The icons that display for files in Windows are saved in an icon cache so they can be displayed quickly instead of having to manually scan and slowly load them each time.

Sometimes you may notice File Explorer loads icons slowly when you open a folder with lots of files. Increasing the size of the icon cache may help.

By default, the icon cache is 500 KB. Increasing the icon cache size to 4 MB gives the best results, but you can change the size to what works best for you.

This tutorial will show you how to change the maximum size of the icon cache to fix slow loading icons in File Explorer for all users in Windows 7, Windows 8, Windows 10, and Windows 11.


You must be signed in as an administrator to change the icon cache size.

3 In the right pane of the Explorer key, double click/tap on the Max Cached Icons string value to modify it. (see screenshot above)

If you notice icons loading slowly when you open a folder, then it may be a good idea to increase the icon cache size to see if it may help them load faster next time. :)
