The wait is over. Microsoft has finally released Windows 8.1 to the public as a software update. Users currently on a legitimate/genuine copy of Windows will be able to go to the Store app on Windows 8 and download the update for free from there. Those with Windows 7 will be able to upgrade to Windows 8.1 for the same price as Windows 8.1. The boxed retail version of Windows 8.1 will be available tomorrow.
At the time of posting, I just started downloading the upgrade for my Windows 8 VM. Once I have finished, I will be playing with it and giving you my first impressions.
