The application works by re-adding the lost button seen on Windows 7 and prior editions of the OS. It can be customized as desired so you can access applications directly from the menu and organize them however you like.
It also incorporates the classic search bar from Windows 7. You can even adjust the size of the included tiles according to your needs.
If you have the latest 8.1 version, on the other hand, you can adapt Anvi OneStart to the new button that Windows added to this version, meaning you can still use it even if you have the default Windows button.
