Windows 10 has become the most popular PC operating system in the world. Regardless of whether you already have Windows 10 or not, you might want to keep an ISO file with the Windows 10 setup around. You never know when you might need it: upgrading an older Windows 7 or Windows 8.1 PC, reinstalling your Windows 10 or helping a friend in need, when his or her computer breaks. If you want to know how and where to download Windows 10, worry not. Here are three ways to download Windows 10 for free and completely legal:\r\n\r\n\r\n1. Download Windows 10 from Microsoft, using the Media Creation Tool\r\nThe easiest way to download Windows 10 is the method that Microsoft offers to all its users: the company has developed a small application called Media Creation Tool, with which you can download Windows 10 as an ISO file or even create a DVD or a bootable USB stick with Windows 10 on it. You can get the Media Creation Tool from the Windows 10 website. This app is simple and easy to use and, if you need help, read our guide about it: How to create Windows 10 installation media (on a USB stick) or download a free ISO file.\r\n\r\n\r\n\r\nUsing the Media Creation Tool to download Windows 10\r\n\r\nDownload: Media Creation Tool\r\n2. Download Windows 10 from Microsoft\\'s servers, using the Microsoft Windows and Office ISO Download Tool\r\nAnother great way to download Windows 10 is to use an app called Microsoft Windows and Office ISO Download Tool. As its name suggests, this app also lets you download other versions of Windows too, including Windows 7 and Windows 8.1, as well as Microsoft Office. Unlike the other ways we share in this article, the Microsoft Windows and Office ISO Download Tool lets you choose what you want, including older versions of Windows 10.\r\n\r\n\r\n\r\nYou can download Windows 10 in any language, and you can choose the edition you want with just a few clicks.

Download Windows 10 from safe download sites, such as Softpedia\r\nThe third way to download Windows 10 is to do it from popular download sites. However, this is also the riskiest method, because many of the websites that offer software for download are not exactly honest and some can even distribute malware hidden in the downloads that they offer. Unfortunately, most of the large download portals that have a good reputation, such as FileHippo, Cnet, and MajorGeeks, do not include direct links for downloading Windows 10. The best website we could find that offers direct downloads for Windows 10 ISO files, is Softpedia. Visit it, search for Windows 10 and you should see the download options in the first results.\r\n\r\n\r\n\r\nThe Windows 10 download page from Softpedia\r\n\r\nDownload: Windows 10 on Softpedia\r\nWhat is your favorite way to download Windows 10?\r\nThese are the methods we know for downloading Windows 10, free of charge, safely, and legally.
