How to Easily & Legally Download Windows 10 & 8.1 ISOs

We often advocate to back up your data and keep a rescue disk in case your a Windows decides to go south. Along with a rescue, it’s also good to keep a USB ready installation of your Windows. Not only does it save you time, you can also customize it to your liking. But for all the above things, Windows ISO file is needed. Currently, for Windows 10 you can download it using the MCT, selecting the Create installation media option. A similar tool is also present for Windows 8.1.

But downloading through the tool means you can’t use your favorite download manager and obviously it will not work on other OSes. There is a workaround where some source code trickery enables you to download the ISO from the browser but that’s just too many steps. We always strive for simpler solutions and so we have got one for this too Let’s see what it is.

The Easier Way

When you do a Google search for Windows X ISO, the top result is generally from Microsoft followed by some how-tos and torrent links. Visiting Microsoft’s official link, you get an option to download the above-mentioned tools. This is because MS detects your browser & OS and offers the tool. But if you change your user agent to a mobile browser or Mac you will get download links for the ISOs. Now let’s see how to do that step by step.

For Firefox

Step 1: Add the User Agent Switcher from here. Restart Firefox after installation.
