Description
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.
