October 26, 2012, 10:23 AM — Ready or not, Windows 8 is here. One of the most controversial versions of the operating system ever released, its main interface feels designed more for touch-screen tablets than traditional computers. What's more, the Desktop has been hidden away and weakened with the removal of the Start button.
But I'm not here to talk about the controversy. I'm here to help you use Windows 8, because whichever version of Windows you're upgrading from, you'll find it a new experience. The horizontally oriented Start screen (once called the Metro interface) sports big tiles that practically beg you to touch them. And the Start screen and the Desktop feel as if they're dueling operating systems, because each works differently from the other in many ways.
All this might sound overwhelming, but as you'll see, it's not that tough to master Windows 8. In this cheat sheet I'll show you how to get the most out of the new Start screen and its apps, the Desktop, the new Charms bar, Internet Explorer 10 and plenty more. I've also provided quick reference charts listing useful touch-screen gestures and keyboard shortcuts.
Note: If you want to get the most out of Windows 8, you'll have to use a Microsoft ID as your user account. Without a Microsoft ID, you won't be able to use a number of new Windows 8 apps, including Mail and People, and you won't be able to sync settings among multiple devices. So when you set up Windows 8 for the first time, sign in with an existing Microsoft ID or create a new one. (You can also switch to a Microsoft ID account later on via the "PC settings" screen.)
There's a new lock screen in town
When you start Windows 8 (whether booting up initially or waking from sleep), you'll see the first big difference from previous versions of Windows -- a whole new look for the lock screen. Like the lock screens on Windows Phone devices, it sports a big graphic image and displays a variety of information, such as the date and time, the local weather, the number of new emails you have, the strength of your network connection and how much power you've got left on your device.
