Windows RT is a limited version of Windows 8 that runs on ARM-based devices, not on traditional PCs. It is installed as the operating system for the new “SURFACE” tablet Microsoft has recently introduced.
Windows RT will not run any desktop Windows applications beyond the applications that are bundled with the operating system. Bundled applications include virtually every single desktop application found in Windows 8—Paint, WordPad, etc.—except for Windows Media Player. It also includes a fully-functional and full-featured version of Office 2013 called Office Home & Student 2013 RT. This suite includes Word, Excel, OneNote, and PowerPoint. For the umpteenth time, it does not include Outlook.
Windows RT will not run any desktop applications beyond the applications that are bundled with the operating system. This means it will not run Windows Essentials 2012, Microsoft Outlook (any version), Microsoft Office (any version, beyond what’s included with RT), Adobe Photoshop or Photoshop Elements, or any other Adobe desktop application. It will not run the SkyDrive desktop application (which is part of Essentials 2012, yes, I know), meaning you cannot sync SkyDrive data to your RT device’s storage. You can only use the SkyDrive Metro app, which lets you access SkyDrive only when connected … just as with any other mobile device. It will not run iTunes. It will not run any desktop Windows application beyond what’s bundled with the OS.
Windows RT is not a computer operating system. Windows RT is an operating system for mobile devices.
Surface with Windows RT is not a computer. It is mobile computing device, like an iPad. It is a tablet, a hybrid device that bridges the gap between real PCs and media tablets, where you can work and play.
