Get the best of work and play

Upgrade your PC to Windows 8.1 and discover new ways to get things done and have more fun.

Or get the upgrade on DVD from the Microsoft Store.

Clicking Upgrade now installs Windows Upgrade Assistant, which makes sure your PC can run Windows 8.1 or Windows 8.1 Pro and gives you the option to purchase either. When prompted by your browser, open, save, or run Upgrade Assistant. Depending on your Internet connection, Upgrade Assistant might take several minutes to install.
