f you currently have a personal computer running Windows 7, Windows XP with SP3 or Windows Vista then you can upgrade to Windows 8 Pro (Professional). With Windows 8 Pro, you can connect and share your files. Windows 8 Pro also adds enhanced features if you need to connect to company networks, access remote files, encrypt sensitive data, and other more advanced tasks.
The new Windows 8 start screen is your personalised home for items you use the most and can be customised according to your user preferences. Windows 8 Live tiles provide real-time updates from your Facebook, Twitter, and e-mail accounts. Along with the new Start screen, the lock screen now includes e-mail, calendar, and clock widgets.
To access your PC, Microsoft has replaced a standard PIN or password with a swipe gesture; unlock your PC by clicking or swiping preset locations you’ve selected on the lock screen. New functions also allow you to search for your favorite software programs, open, close, hide, resize, or run multiple apps simultaneously with the swipe of a finger or a swipe of the mouse.
Windows has also made changes to make your PC more secure by boosting its existing security features and adding "SmartScreen," which acts to prevent suspicious programs or apps from being installed or running on your machine. Finally, Windows 8 also gives you the ability to "refresh" itself to give users a new starting point and a cleaner version of Windows.
You can upgrade to Windows 8 from Windows 7, Windows Vista, Windows XP, Windows 8 Release Preview, Windows 8 Consumer Preview, or Windows Developer Preview, but you might not be able to keep all of your files, software programs, and settings. The following table shows what you can keep during an upgrade, depending on the current version of Windows you are running.
