It's not everyday that a company leaks stuff that they are seriously chapped about getting online early. Microsoft leaked Windows 8.1 Update 1 the other day and if you don't want to wait a month for it to hit Windows Update, there are several ways you can go get it. You can do a bit of a registry tweak and then it should download directly. If you're not feeling that adventurous, there are some direct download links as well. Take a look and get your update on if you're feeling a bit brave. It should be all good though as it has been RTM for a while now.
Most of the changes in the update are designed to appease keyboard and mouse users, with options to show Windows 8 apps on the desktop taskbar, the ability to see show the desktop taskbar above Windows 8-style apps, and a new title bar at the top of Windows 8 apps with options to minimize, close, or snap apps. Microsoft is also adding a shutdown button to the Start Screen for non-touch machines, with a new search button present across all machines.
