Only if you currently have a device running Windows 8.1 (Core) operating system can you upgrade to Windows 8.1 Pro (Professional) using this Windows 8.1 Pro Pack (upgrade) product.
Windows 8.1 Pro allows you to connect and share your files and also adds enhanced features if you need to connect to company networks, access remote files, encrypt sensitive data, and access to other more advanced tasks. To access your PC, Microsoft has replaced a standard PIN or password with a swipe gesture; unlock your PC by clicking or swiping present locations you've selected on the lock screen. New functions also allow you to search for your favourite software programs, open, close, hide, resize, or run multiple apps simultaneously with the swipe of a finger or a swipe of the mouse.
Finally, Windows 8 also gives you the ability to 'refresh' it-self to give users a new starting point and a cleaner version of Windows. Use BitLocker Drive Encryption to help protect your files on an entire drive. BitLocker can help block hackers from accessing the system files they rely on to discover your password, or from accessing your drive by physically removing it from your PC and installing it in a different one.
With Remote Desktop you can connect your PC to a PC in another location, like your work PC to your home PC and use all of your apps, files, and network resources as if you were sitting right in front of your work PC. You can leave apps open at work and then see those same apps on your home PC. Watch, pause, and record HDTV, watch DVDs, listen to your tunes, show off your photos, and enjoy online shows.
