which of the following windows does not have start button
Windows 8 On February 29, 2012, Microsoft released Windows 8 Consumer Preview, the beta version of Windows 8, build 8250. 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.[31][32] Windows president Steven Sinofsky said more than 100,000 changes had been made since the developer version went public.[32] The day after its release, Windows 8 Consumer Preview had been downloaded over one million times.[33] Like the Developer Preview, the Consumer Preview expired on January 15, 2013.
