The Charms bar lives hidden under the right edge of your screen. On touch screens and touch pads, you can reveal it by swiping in from the edge. With a traditional mouse, move the cursor to the upper-right corner and it will appear. Hot keys on your keyboard will work, too. Win + C will open the Charms, and there are specific combinations to access its features -- such as Win + Q for Search.
Opposite the Charms bar, the left edge lets you flip through recently used apps. Swipe in from the edge to go to your last app. If you make a sharp U-turn with your finger, you'll get the recently used apps sidebar. If you're using a mouse, move the cursor to the upper-left or lower-left corner to reveal the sidebar.
The Metro version of Internet Explorer 10 is remarkable for its unique interface, its fast page-load times, and its surprisingly effective security policies. It also has Do Not Track turned on by default, setting the stage for a battle between Microsoft and advertisers.
Socialization, sync, and sharing are big parts of the Windows 8 experience. The People app is where all your contacts will integrate from across multiple services. Here, we show the app with the Accounts setting sidebar open.
The Windows Store, with its hidden top-edge navigation pulled down in this screenshot, is where you'll go to get the new Metro-style apps. Unlike Google and Apple app stores, though, the Windows Store is really for apps only. Confusingly, Music, Video, and Xbox games -- but not Windows games -- must be purchased through their built-in app marketplaces.
One of the coolest things about Windows 8 apps is the semantic zoom. Pinch to zoom on the screen or a touch pad, or use the scroll wheel on your mouse, and many apps will reveal a top level to their content that allows you to easily jump around within the app. This can also be used on the Start screen to skip across app groups.
On Windows 8, the Windows 7-style traditional interface lives as an app called Desktop. Many legacy programs, and some advanced Windows configuration tools, will launch into the Desktop. It still has Charms and recent-apps bar access, though, so it's quite easy to jump between the two.
After almost 20 years, the Windows Explorer (not to be confused with Internet Explorer) gets rebranded as File Explorer in Windows 8. It also introduces some excellent new tools specific to each library.
From the moment the Start screen is staring you in the face, you can start typing away. It's a subtle but incredibly powerful search tool that makes the Metro interface much more accessible to keyboard junkies.
You can right-click with a mouse on your apps to get extra context-menu style options for them. But how do you do it by touch? It's quite simple: just swipe down on a tile to select it, and swipe down again to deselect it.
Windows traditionally gets bogged down in its own muck over time, with clean installs generally performing better than older ones. It's not clear if that'll happen with Windows 8, but in case it does, Microsoft has included in PC Settings two options for renewing the OS's lease on life.
Refresh keeps your files as it reinstalls Windows 8, while Remove everything and reinstall wipes the slate entirely clean. Convenient!
