How to Change Icon of a Folder in Windows 10
This tutorial will show you how to change the icon of a folder in File Explorer to any icon you like in Windows 10.
When you change the icon of a folder, the folder will no longer show a thumbnail preview of its content until you restore the default folder icon.
1) Right-click or press and hold on the folder you would like to change, and click/tap on Properties.
2) Click/tap on the Customize tab.
3) Click/tap on Change Icon.
4) Browse to an icon library, click/tap on an icon, and click/tap on OK.
You can also find more icons at C:\Windows\System32\imageres.dll. Also, if you have a custom icon pack you can select 'Browse' to find your custom icons and then apply them. However, once you have done that you shouldn't move the custom icons. If you do, the folder using the custom icon will go back to the default folder icon and you will have to go through the entire process again.
You can click/tap on the Restore Defaults button and click/tap on OK to restore the default icon of this folder.
5) Click/tap on Apply.
6) And now you're done!
