You can use installation media (a USB flash drive or DVD) to install a new copy of Windows, perform a clean installation, or reinstall Windows. To create installation media, go to the software download website, where you'll find step-by-step instructions.

There are several types of files you can download from the web—documents, pictures, videos, apps, extensions and toolbars for your browser, among others. When you select a file to download, Internet Explorer will ask what you want to do with the file.
