Window 8 support

New to Windows 8?Windows 8 represents a fundamental shift in the way Windows works and is far more touchscreen-orientated for use on tablets as well as traditional PCs. If you're completely new to Windows 8 and haven't used a preview version, we'd recommend you check out our guide to the new features you'll find in Windows 8 vs Windows 7 and Windows 8: what you'll need to relearn.

• Windows 8 vs Windows RT: what's the difference?

Much of what we're seeing in the RTM will be the same on Windows RT systems as it is in Windows 8. Most features - from the Start screen user interface to the touch gestures, to the Windows desktop and built-in Windows tools such as File Explorer and Task Manager - will be practically identical (although we don't have a definitive list of which built-in tools will be built in with Windows RT).

The vast majority of apps in the Windows Store will run on both. Microsoft has even confirmed it will offer Flash functionality for IE on Windows RT (at least on what it calls the "initial delivery of Windows RT PCs").

But until we see it in action, we don't know what Windows RT performance and battery life will be like (although the promised battery life for Connected Standby and HD video playback looks impressive, at up to 409 and 13 hours, respectively).
