How to download Windows 10 (build 15002) Insider Preview ISO files

Microsoft continues to offer Windows 10 Insider Preview ISO files to do clean install of the latest test builds. Here's how to download them.

Download Windows 10 Insider Preview ISO files

Microsoft begun with the Windows Insider Program long before Windows 10 released to the public. The company created the program to allow enthusiasts and developers get their hands early on features and improvements.

Users were able to install previews of the operating system by downloading the ISO files available through the Windows Insider Program website. However, after Windows 10 was released to the public, Microsoft stopped delivering ISO downloads, in favor of using Windows Update as the delivery mechanism.

Windows Update has shown improvements as a reliable mechanism to get new test versions of Windows 10. The problem is that the installation files can take a long time to download, and if you want to do a clean install, you need to reinstall a previous version and then go through the upgrade process, which can take some extra time.

After a number of feedback, Microsoft quietly decided to reinstate the ISO files to enable users to perform an offline clean installation of Windows 10 Insider Preview builds.

Now every time a new flight becomes available for the Windows 10 Creators Update or for another version, you can now get the new build from this Microsoft website. However, keep in mind that Microsoft will only be making available ISO files for Windows 10 Insider Preview for builds released in the Slow ring — not during the flight is available in the Fast ring.

Once you’re in the download page, you will need to choose the edition, and click Confirm to download. Once you finish downloading the ISO file, you can use different tools, such as Rufus to create a USB bootable drive to install the operating system.

You can download the ISO files for Windows 10 Creators Update build 15002, which is the latest preview available through the Slow ring. However, if you need to download a previous release, you can still download Windows 10 build 14986.

If you’re looking to upgrade your computer running Windows 7 or Windows 8.1, or you need to do a clean install of Windows 10, Microsoft is also making available the ISO files for the official version of Windows 10, which you can get using the Media Creation Tool or through the Microsoft support website.
