You will require a minimum of 2GB empty space on your hard drive, though the more space there is, the better it will be. This preview of Windows 8.1 is only available to download for people who are running Windows 8 with a legal product key and license. While the Windows 8.1 download is available, it must be noted that it is just a preview. Microsoft has always worked in this way. They release preview builds for the audience which acts as a sneak peak into what Microsoft has to offer. Every new iteration of Windows usually gets such builds and the official licenses are only given to developers who test the builds as beta testers.
The process is fairly easy to follow and is fairly automated. Once Windows 8.1 download is completed it automatically installs and asks you to reboot. You may have to reboot more than once as there are some glitches we faced while installing. Once your laptop/PC has booted up the process to setup windows 8.1 is flawless.
Just follow all the messages and prompts on your screen and get the latest Windows 8.1 preview build!
