the Start Menu has the same design as the one demoed off at BUILD 2014 in San Francisco earlier this year — full of Live Tiles, and all that cheese.
But once these Live Tiles are removed, you are left with a Stat Menu that resembles the one available in Windows 7. The classic Start Menu should be quite welcome by those that wish to retain the similar look and feel of the desktop in Windows 9.
we have confirmation of another configuration option in the upcoming operating system that will allow users to enable or disable a particular feature as they see fit. as if you changed the color of your desktop the start menu color will changed too.
Microsoft had everyone getting the preview sign confidentiality agreements to make sure they wouldn’t publish screenshots or information online, again in an attempt to keep everything secret until the beta sees daylight. so i believe that windows 9 won't be leaked until October.
