Turn off display of recent search entries in the File Explorer search box Disables suggesting recent queries for the Search Box and prevents entries into the Search Box from being stored in the registry for future references. File Explorer shows suggestion pop-ups as users type into the Search Box. These suggestions are based on their past entries into the Search Box. Note: If you enable this policy, File Explorer will not show suggestion pop-ups as users type into the Search Box, and it will not store Search Box entries into the registry for future references. If the user types a property, values that match this property will be shown but no data will be saved in the registry or re-shown on subsequent uses of the search box.
