Here's a look at how to get your Windows 8 system ready and the process of upgrading to Windows 8.1 through the electronic update now available in the Windows Store.
Instead of doing traditional Windows deployment projects, you will need a continuous updating process which will reduce the overall effort required to maintain Windows 10 devices in your environment.

The next screen will give you a brief preview of what new features Windows 8.1 provides. Now just wait while the update is downloaded and installed.
If you have the option of a wired Ethernet connection rather than Wi-Fi, I'd recommend using it to provide a much more reliable connection for faster download speeds and to reduce the risk of getting disconnected during the install.
