This update adds Start button, new Start screen customization settings, option to directly boot to desktop, updated Windows Store, picture lock screen, Internet Explorer 11, and hundreds of wonderful features to Windows 8. According to Microsoft, Windows 8.1 includes over 800 changes.

While users who upgrade Windows 8 to Windows 8.1 don’t need to enter a product key, other users who who would like to perform a clean install of Windows 8 will be asked to enter a product key during the installation.

According to Microsoft, all users can use the NTTX3-RV7VB-T7X7F-WQYYY-9Y92F product key to install and activate Windows 8.1 Preview.

Important: Please don’t upgrade your existing Windows 8 installation to Windows 8.1 Preview as you will need to reinstall all installed apps and desktop programs while upgrading Preview build to Windows 8.1 final (RTM). Instead, either install Windows 8.1 Preview in dual boot with Windows 8 or install it in virtual machine using VMware Player or VirtualBox.
