How to download and install Windows 10 directly from Microsoft.
Follow these steps to create installation media (USB flash drive or DVD) you can use to install a new copy of Windows 10, perform a clean installation, or reinstall Windows 10.
Before you download the tool make sure you have:
An internet connection (internet service provider fees may apply).
Sufficient data storage available on a computer, USB or external drive for the download.
A blank USB flash drive with at least 8GB of space or blank DVD (and DVD burner) if you want to create media. 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 are told the disc image file is too large you will need to use Dual Layer (DL) DVD Media.
