If you are a regular Windows user, the first thing that hits you when you load Windows 8 on your screen is confusion. So, in order to help you get your head around this operating system, let’s begin with navigation first.
Speaking of keyboard and mouse navigation, the first thing that you must do is to move your mouse to either the lower or upper right hand corner of screen to access the Charms bar, where you will find key system functions such as the Windows (center) and the Settings icon (at the bottom).
Another feature comes into play when you run your first Windows app, and for this, you have to open an app and move your mouse pointer to the lower left corner of your screen – and you will find a bar which displays all apps running in the background.
Keyboard shortcuts include holding down the Windows key along with another key, and some of them include:
Windows-D: Takes you back to Desktop
Windows-C: Opens the Charm bar
Windows Key: Switches between Windows and the last application used.
Windows-I: You can access Windows settings or even opt to shut the computer.
As for pre-installed apps, some of them include Mail, People, Calendar, Messaging, Photos, Store, Music, Video and SkyDrive.
Finally, in order to access the workgroups that you might have created in the past, the easiest way to set this up is by accessing the Control Panel using the Charms Bar shortcut. As opposed to Windows 7, you can change User Settings in Windows 8 in two ways: either through the control panel or even bring it up directly by opening the Charms bar and PC Settings as well.
