Windows RT
Windows RT or Windows 8 RT is an ARM version of the Windows 8 operating system optimized for tablets. The operating system was introduced in 2012 when Microsoft launched the Surface RT and the original Surface Pro.
The benefits
One of the key benefits of the RT version of the OS is it’s bundled with a free Microsoft Office 2013 RT, which includes the touch-optimized desktop versions of Microsoft Word, Excel, PowerPoint, OneNote, and Outlook. All Windows RT devices also support the InstantGo feature and BitLocker technology for better accessibility and security.
The limitations
One main issue of Windows RT is it is built for ARM architecture which is different than the traditional x86 and x64 Windows operating systems. It means all existing desktop applications will not run on Windows RT devices, except newer applications built and compiled for ARM32.
You can only install apps and games from the Windows Store and use the peripherals with drivers designed for Windows RT.
The OS also lacks support for other essential applications and enterprise features like Windows Media Player, Windows Media Center, HomeGroup, remote desktop services, and domain join.
The latest version
Windows 8.1 RT is the latest version for Windows RT, as well as Surface RT, Surface 2, and other Windows RT devices. It was available in late 2013 when the company launched the Surface 2 and Surface Pro 2.
The Windows 8.1 RT Update 3 is the latest major update for the OS by introducing the new Windows desktop experience with a familiar classic start menu designed inspired by Windows 10.
