Upgrading from Windows 7 to Windows 8.1 is possible for computers possessing the right system requirements. An individual with a compatible computer can purchase Windows 8.1 online and download it or purchase a compact disk from an authorized retailer.
Microsoft offers Upgrade Assistant, a free downloadable program that walks individuals through the process of upgrading their personal computers. The program analyzes the computer to see if it is compatible, gives its owner the option to preserve personal files, and helps with purchasing, downloading and installing Windows 8.1. An upgrade does not preserve programs and settings; individuals may reinstall their programs after the upgrade.
