In one of our previous posts, titled how to download Office 2013 from Microsoft using a product key, we discussed how to legally download Office 2013 setup from Microsoft by entering a genuine product key. The guide is useful for those who have lost their Office DVD and also for those who are having issues with the original Office DVD.
In addition to Office 2013 and 2010, one can also download the original Windows 8 and 8.1 ISO image files right from Microsoft by just entering required product key. As you should know, one can use the Windows 8/8.1 Upgrade Assistant to easily download Windows 8/8.1 ISO right from Microsoft. You just need to enter your product key to begin downloading setup files and then create bootable USB or ISO image file.
While some OEMs provide recovery image in a dedicated partition (drive) or recovery DVD when you purchase a new PC preinstalled with a version of Windows, the catch is that these recovery images or DVDs install trial copies of several third-party software and uninstalling these trial software itself is a tedious task.
Unlike Windows 8 and Windows 8.1, Microsoft doesn’t offer a way to download its Windows 7 OS via Windows Upgrade Assistant. However, Microsoft does offer a way to download genuine Windows 7 ISO image and is much easier than downloading Windows 8 or Windows 8.1 ISO, as you don’t need to download and run the Upgrade Assistant. The other advantage is that you don’t need to provide a genuine key to start the download, meaning that you can begin downloading Windows 7 ISO even if you can’t locate the product key at the moment (see how to recover product key).

One can download official Windows 7 with SP1 ISO image files by visiting the link mentioned at the end of this article. The download link lets you download both 32-bit and 64-bit Home Premium, Professional, and Ultimate editions of Windows 7.
