Update Surface from Windows 8.1 Preview

If you’ve been using the preview version of Windows 8.1, you need to update to Windows 8.1. This update is free for all Surface Pro users. After you update to Windows 8.1, you can upgrade to Windows 10 if you want.


If you haven’t updated to Windows 8.1 yet, you’ll get a message when you sign in telling you that your license for Windows 8.1 Preview has expired. This article tells you how to get Windows 8.1 installed on your Surface Pro.

How do I know if I’m using a preview version on my Surface Pro?

Step 1: On the Start screen, tap or click the Desktop tile.
Step 2: Close or move any windows that cover the lower-right corner of the screen.
Step 3: If you see the version of Windows you are using and the words Evaluation copy in the lower-right corner, it’s time to update.

If you are using a Surface Pro 2, Surface Pro 3 or Surface 3, you are already running Windows 8.1 or Windows 10.

Before you update

  • Make a list of the apps that you got from the web or loaded from a disk. Make sure you have your registration information for those apps. If you installed from a disk, have that disk handy.
Note
Apps that you got from the Windows Store are associated with your Microsoft account and are ready for you to install. You need to make your list only for apps you got elsewhere.
  • Back up your personal files. If you keep your files on OneDrive, they are already backed up.
