Windows 9 will reportedly ship in 2015, codenamed ‘Threshold’
What will Windows 9 include? Well, Thurrott believes that we’ll see Microsoft discuss its next-gen OS at its upcoming BUILD developer conference being held in April. Thurrott believes that Microsoft will shift away from the Windows 8 name after all of the problems associated with it, and will drop the Windows 8 branding in favor of Windows 9 – this could change, but right now this is what he believes will happen.
