As a lot of have noticed, the Explorer of the newly released version of Windows Vista OS doesnt have the accustomed button for upward movement. As an alternative, the developers of the software offer the key shortcut that was implemented yet in the previous version.They as well offer the user to click the folder in the upper row that is always located in different places of the navigation line. Just like a lot of others, we had a distinct feeling something really necessary was missing. As a result, we developed this simple feature that is now available to you! Mavis Up Button for the Windows Vista Explorer is now available to you! An accustomed convenience. Easy to install and remove. Weight less than 30 kb of RAM. No changes to the Explorers code.
