If you wish to see all available settings, you can select the All Settings option at the bottom of the screen. Feel free to modify the settings without fear as you can easily revert back to the default settings by clicking on the Backup button and then selecting Reset All Settings.
The Skin tab in the Settings screen allows you to change the appearance and graphical user interface of the Start Menu. Once again, these settings can be changed without fear of messing anything up as you can always reset them by going through the Backup button.
As you can see, Classic Shell is a great program that allows you to add the Start Menu back to Windows 8 without losing any functionality. If you are upgrading to Windows 8 and want to continue to use a Start Menu, then this free program is the way to go. If you have any questions regarding this program or how to use it, please feel free to ask us in the Windows 8 forum.
