Everyone wants to try Windows 8 Consumer Preview. You've downloaded the software and installed it leaving just one task left: actually using the thing.

The Windows 8 Consumer Preview drops you in at the deep end. Unlike Windows of old, which has taught users how to handle the user interface with mouse tutorials and bouncing arrows, Windows 8 just dumps you at the lock screen. Swipe or drag that out the way, and you're faced with the brand new Start screen. This will be a bit of a shock to existing Windows users (which is to say, virtually every person on earth who has ever owned a computer), and getting to grips with the Windows 8 interface is going to require some effort.

We first used the interface with the Developer Preview, and the fundamentals haven't changed since then. The interface is built around two things: the Start screen and the charms bar. The Start screen is a full-screen, Metro-styled successor to the Start menu, and the charms bar is where various global functions—search, share, devices, and settings—reside (it also contains a Start button to bring up the Start screen).

For touch systems, the interactions are simple enough. Familiar from the Developer Preview, swiping in from the right brings up the charms, swiping from the top or bottom brings up the toolbar-like application bar, and swiping in from the left flicks between tasks. Swiping in from the left and then back out brings up a thumbnailed view of running applications for direct switching to a particular app, rather than cycling through all running apps.

New to the Consumer Preview is the ability to manually close applications with gestures. Start swiping an application from the top of the screen, and it shrinks down to a large thumbnail. This thumbnail can be dragged to the left or the right of the screen, to snap it, or off the bottom of the screen, to close the application entirely.

The Start screen can be visited by using its button on the charm menu, or using the hardware Windows key that all Windows 8 tablets are required to have.

Throughout, pinch to zoom and two finger rotate gestures work in the places you might expect them to work. They also work on the Start screen, in the Windows Store, and in applications that have similar tile-based layouts such as the new Vimeo application. In these applications the zooming is not simple scaling; it simplifies the layout, for example replacing live tiles by their respective icons. This feature, that Microsoft calls semantic zoom, allows easier navigation of large lists.

Though the operating system lacks any significant cues to perform any of these actions, once learned they're used consistently and rapidly feel natural.

The mouse and keyboard approach is a little less obvious. Windows users are familiar with clicking on the Start button to bring up the Start menu, but the Start button is gone. Windows 8 instead uses hot corners. Clicking in the bottom left of the screen brings up the Start screen. Clicking the right hand corners brings up the charms (both corners have the same effect). Clicking the top left corner brings up the application switcher.





This has some oddities. When the mouse is in the Start screen's corner, a little stylized image of the Start screen appears. This shows a kind of super-zoomed out view of your own Start screen. It's tempting to try to click on this—but moving the mouse out of the corner usually results in the image going away (though sometimes it doesn't). The temptation to click the graphic must be resisted, and the mouse must be clicked in the very corner.

Right-clicking the hotspot yields a special menu of handy items (Task Manager, Control Panel, Command Prompt, and more), a little treat just for the mouse users.

The top left corner behaves similarly strangely. Putting the mouse in the top left shows a thumbnail of the previously-used application. Moving the mouse down then expands the switcher to show all the running applications. But as with the Start thumbnail, moving the mouse as often as not causes the thumbnails to all disappear, which isn't what's wanted.
