Microsoft had plans to release Windows 8.1 updates somewhere in the month of April. However, Thanks to Microsoft’s Windows Update service the links to download a final version of the Windows 8.1 Update has been discovered.
It is always recommended to download the update when its officially released in April, but in case you are in hurry to get Windows 8.1 update then head My Digital Life Forum.
As per the verge:
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.
