Important: Back up your files before you install or reinstall Windows on your PC. Learn how for Windows 10 or for Windows 7 and Windows 8.1.

To create the installation media, here's what you'll need:

A PC with a reliable internet connection. The download time will vary, depending on your internet connection.
A USB flash drive or DVD. A blank USB flash drive with at least 8 GB of space, or a blank DVD (and DVD burner). We recommend using a blank USB or blank DVD because any content on it will be deleted. When burning a DVD from an ISO file, if you're told the disc image file is too large, you'll need to use dual layer (DL) DVD media.
A product key. Your 25-character product key (not required for digital licenses). For help finding it, go to Find your Windows product key.
