Download Windows 10 Pro ISO File Without Product Key From Microsoft

Here’s how to download official Windows 10 Pro ISO file legally without needing any product key directly from Microsoft. More info on this is detailed in the post below.

We understand that the majority of users would have downloaded Windows 10 directly through ‘Windows Update’ as part of the free-of-charge upgrade process when it was available, but now that it isn’t, and for those in need of an official Windows 10 ISO file, we are here to help you out.

Microsoft has clearly attempted to make sure that all bases are covered as far as installation options are concerned. Although the company started initiating pre-downloads of the operating system to registered PCs approximately 24-hours before the official launch in late July of 2015, it does appear to recognize that some consumers would require an official ISO image of the Windows 10 platform whenever the need to manually install or reinstall the OS on a formatted machine arises. The ISO image will of course allow for the creation of a bootable USB flash drive or DVD, to serve as an installation source.

Best of all, you don’t need any product key to download the ISO media file from Microsoft. Just about anyone can download it officially from Microsoft as long as they have an Internet connection. Though it is important to note that genuine Windows product key will be required for activation purposes during or after installation.

As part of this ISO file offering by Microsoft, the company has also created a relatively small check list of what’s actually required before beginning the download:

An active and reliable Internet connection.
Enough storage space available on the computer being used to download the ISO.
A blank USB storage device or DVD with at least 4GB of space for the creation of media. There’ll also be the requirement for a DVD burner if that’s your chosen medium.
Make sure your PC meets all other Windows 10 requirements, you can check those here: How To Prepare Your PC For Windows 10 The Right Way [Guide].
As mentioned above, if you are doing a clean install, a genuine Windows product key will be required during installation process. Here’s guide on clean installing Windows 10: How To Clean Install Windows 10 On Your PC The Right Way [Guide].

If all of those criteria are met, then here’s what you need to do.

Step 1: First goto Microsoft’s official Windows 10 Disc Image (ISO) download page here.

Step 2: When you are on that download page, select your desired edition, as can be seen in the screenshot below:

Step 3: Once you have selected the edition, select your desired language, this too should look familiar to what can be seen in the screenshot below:

Step 4: Once done, you will get two options, to download in either 32-bit or 64-bit. Select the preferred option and then simply download it.

It really couldn’t get any simpler, and it’s great to see that Microsoft has attempted to cover all avenues with this Windows 10 release.
