How to Upgrade From Windows 7 to Windows 8.1

Windows 7 to 8.1If you’re one of the millions of users who didn’t want to upgrade your PC from Windows 7 to Windows 8, perhaps Windows 8.1 will change your mind about migrating. The new operating system offers improved multitasking with its split screen mode, a universal search that queries both the web and your hard drive and a slew of new apps such as Facebook and Food & Drink. Unfortunately, the upgrade from Windows 7 to 8.1 will not preserve  your programs or settings, but fortunately it is an easy process if you follow these steps.

Before You Begin

While Windows 8.1 will retain some of your information after you upgrade, we wouldn’t recommend you count on that. Make sure that you have backed up all personal files (documents, photos, videos, music) either to another hard drive or to the cloud. Windows 8.1 will not keep any of your Windows 7 desktop apps installed after the upgrade so make sure you have copies of all your installer files and associated product keys.
