Microsoft's next operating system will come in just three different flavours, the company has announced. For those with Intel-compatible machines, the OS will be available in two versions - Windows 8 and Windows 8 Pro.
The complex flavours of past Windows - from basic to home, premium to ultimate - have become something of a joke among tech experts.
Microsoft has called Windows 8 the most significant redesign of the Windows interface since its groundbreaking Windows 95 OS.
The ARM version of the OS is the newest edition and reflects Microsoft's desire to unify the engine known for running desktop computers with that for tablets and smartphones. Windows RT will sit alongside Apple's iOS and Google's Android operating systems.
