-ARM Edition : it is intended for tablets and PCs powered by ARM processors. It has Microsoft Office (Word, Excel, PowerPoint and OneNote) pre-installed and has device encryption.
“First, Windows 8 is the official product name for the next x86/64 editions of Windows. For PCs and tablets powered by x86 processors (both 32 and 64 bit), we will have two editions: Windows 8 and Windows 8 Pro. For many consumers, Windows 8 will be the right choice. It will include all the features above plus an updated Windows Explorer, Task Manager, better multi-monitor support and the ability to switch languages on the fly [...] Windows RT is the newest member of the Windows family – also known as Windows on ARM or WOA, as we’ve referred to it previously. This single edition will only be available pre-installed on PCs and tablets powered by ARM processors and will help enable new thin and lightweight form factors with impressive battery life. Windows RT will include touch-optimized desktop versions of the new Microsoft Word, Excel, PowerPoint, and OneNote.”
