Step-by-step: Update to Windows 8.1 through the Windows Store
As I described in Get the ISO you need to create your own Windows 8.1 DVD, if you have more than one Windows 8 system that you need to update to Windows 8.1, you'll want to download a Windows 8.1 ISO image that you can use to update multiple systems.

In this article I'll walk you through the entire Windows 8 to Windows 8.1 upgrade procedure using the Windows Store.
