How to Download a Win 11 ISO File and Do a Clean Install
You can get a Windows 11 ISO and create a bootable install disk.
Whether you're building a new Windows PC or just want to make a completely fresh start on your existing computer you will need to perform a clean install of Windows 11, booting off of an install disk and writing the new OS to your storage drive. In order to create a bootable install disk, you will need to get a Windows 11 ISO file that you can write to a USB Flash drive or use as a standalone file if you are installing Windows in a virtual machine.
Whether you have a valid product key or not (see how to get Windows 11 for free or cheap), downloading a Windows 11 ISO never costs anything and there are three main ways to do so. First, you can download a Windows 11 ISO directly from Microsoft or use the company's Media Creation Tool to download the software and write it directly to a USB Flash Drive.
Second, you could use tools from a site called UUP dump to download the files from Microsoft's update servers and build a custom ISO that's fully up-to-date with an insider build that's even newer than release build. Finally, you can use Aveyo's open-source Universal MediaCreationTool to create an ISO that bypasses WIndows 11's TPM requirement.
Below, we'll show you all the ways you can get a Windows 11 ISO and write it to an installation disk.
