I want to know the answer to the following question:
When was the beta version of Windows 8 made available to the public?
All the background I'm provided with is that "Alongside other changes, the build removed the Start button from the taskbar for the first time since its debut on Windows 95; according to Windows manager Chaitanya Sareen, the Start button was removed to reflect their view that on Windows 8, the desktop was an "app" itself, and not the primary interface of the operating system.". Is that enough to answer the question?
