General Clear and Reset Thumbnail Cache in Windows 11


  • Staff
configuration_banner.png

This tutorial will show you how to clear and reset the thumbnail cache for your account in Windows 10 and Windows 11.

Windows keeps a copy of all your picture, video, and document thumbnails in a cache so they can be reused to quickly display when you open a folder instead of having to manually scan and slowly load them each time.

The thumbnail cache can sometimes become corrupted causing thumbnails to display incorrectly or distorted. When this happens, the thumbnail cache needs to be deleted to reset it and automatically recreate as needed.


The thumbnail cache .db files for each user is located in the hidden folder below.

%LocalAppData%\Microsoft\Windows\Explorer
(C:\Users\{user-name}\AppData\Local\Microsoft\Windows\Explorer)

Hello, :-)

This tutorial is for the thumbnail cache instead of the icon cache below for the command you posted.

Hello, :)

That would be a normal SmartScreen security precaution since it's a file downloaded from the Internet. It's 100% safe, but just needs to be unblocked first.

You can see the contents of the BAT file under the download link to help see what it will do. :)

jds63, just shows you not everything is "black & white" ! Then you have to dig deeper to find the truth !

I thought I should post this for the good of the community. This is the only place I will. I scoured the internet trying to find a solution to this problem that Windows 11 would not update my thumbnails on the desktop and would make me hit f5 to refresh every time I moved something to or from the desktop. I spent a few hours following instructions. Nothing worked except, and your going to hate this, I had to reload my machine from scratch, first the OS then programs, then updates, and all my data. It was painful but it worked.

Next time you have an issue like this, be sure to try the procedures in the tutorial and, if that doesn't resolve it, then see if it's a user profile issue by simply creating, and testing with, a new local user account. If it's a profile issue, you can either manually migrate your data and settings to the new user or fix your account the easy way using Account Profile Fixer. Beats rebuilding the whole machine.

No it has not returned. It wrinkled out a couple of other little software bugs too.

So, in terms of a solution, I think it's covered by the tutorial for most cases, but may require a profile refresh in some cases (and using Account Profile Fixer would be the easiest way to do that).
