In an official blog post on April 16, Microsoft’s communications manager Brandon LeBlanc revealed that the company’s next-generation desktop operating system will have three editions - Windows 8, Windows 8 Pro and Windows RT; and that “a no-compromise experience” would be offered by all three editions.
Announcing the naming scheme of Microsoft’s next-generation desktop OS, LeBlanc said in his post on the Windows Team blog that Windows 8 is “the official product name for the next x86/64 editions of Windows,” and that it would be the ideal choice for most of the consumers.
According to LeBlanc, the professional Windows 8 Pro edition is specifically recommended for clients who may want to use their PCs in a "business environment," as the version includes all the features of Windows 8, and also boasts "encryption, virtualization, PC management and domain connectivity."
Finally, about the Windows RT edition, LeBlanc said that the version will essentially be Microsoft’s port to the ARM architecture, and it will only be available pre-installed on the ARM processors-powered desktops and tablets.
LeBlanc also revealed that the Windows RT edition will have an impressive battery life, and will help enable new thin and lightweight form factors. This edition – which will be inclusive of touch-optimized desktop versions of Microsoft Office applications like Word, Excel, PowerPoint and OneNote – will apparently be the new Windows runtime on which “a new generation of cloud-enabled, touch-enabled, web-connected apps of all kinds” will eventually be based.
