If you installed Windows 7 or Windows 8 yourself, you’ll want to find the license key you purchased. This key may be printed on a sticker on your PC’s case or on your laptop. We also encourage you to find your Windows 7 (or Windows 8) key, just in case you need it.

You can choose the option to keep personal files and apps to prevent them from being erased. Proceed with installing the OS by selecting the necessary options. The upgrade process shouldn’t erase your files unless you choose to erase them, but it’s always a good idea to have a current backup-especially when you’re performing a major operating system upgrade. To install Windows 10, download the installation media and run it on your computer.
