When Microsoft released Windows 8.1 last year, consumers were asked to update through Windows Store for the first time. Windows users usually use the built-in Windows update to receive any major updates or bug fixes, Windows RT to Windows RT 8.1 update was not allowed to be done the same way. Because of that, many users didn’t update their Windows RT devices to Windows RT 8.1. To fix this, Microsoft has released an update that enables Windows RT to update to Windows RT 8.1.
If you have enabled Automatic Updates on a computer that is running Windows RT and that has update 2871389 (http://support.microsoft.com/kb/2871389) installed, this update can automatically start the update process to Windows RT 8.1.
This update is available from Windows Update(http://update.microsoft.com)
Making Windows updates more easily (and more cheaply) available is part of the OS team’s overall servicability strategy.
Microsoft’s OS team is trying to get to a point where it delivers updates for Windows around on a more regular basis — perhaps as often as every four months or so, my sources have said. This is what a number of other teams at Microsoft do now, such as the Visual Studio team (three or four updates a year); the Office 365 team (near monthly updates); and the Azure team (monthly or even every three week updates).
