Whenever you hover over an item in Windows 11 File Explorer or on a desktop, you will see a pop-up description.
If you want, you can hide it in Windows 11. Here’s how to do it.
Unselect (to hide) or select (to display) the “Show pop-up description for folder and desktop items” option. You can find this option between “Show encrypted or compressed NTFS files in color” and “Show preview handlers in preview pane.”
Click on the “OK” button.
