Ever since the release of Windows 8, Microsoft is allowing users to download ISO image of the operating system by entering the product key. The downloaded ISO can then be used to create a bootable USB or DVD to install Windows. This is helpful for users who have deleted the recovery image or partition but want to perform a clean install or reinstall of Windows.
In fact, it’s even possible to legally download Windows 8.1 ISO from Microsoft even if you can’t locate the product key. This method is helpful for users who don’t want to recover the product key just to download the ISO file.
