Windows 10 Version 1809 installation .isos can be Downloaded from Microsoft by visiting their website.
Although Microsoft released Windows 10 Version 1809 in October 2018, Microsoft initially had some issues with this version of Windows 10 and pulled the installation .isos down temporary. They re-released Windows 10 Version 1809 in November 2018.
The Windows 10 Version 1809 Installation media automatically inputs all mainstream Windows 8 OEM Product Keys. Windows 8.1 OEM Product Keys and Windows 10 OEM Product Keys during installation and automatically selects the correct corresponding Edition of Windows 10 OEM to install. All Activation Mechanisms with Windows 8 and Windows 8.1 Keys still work despite Microsoft only marketing a 1 year free upgrade.
Windows 10 Version 1809 Installation media accepts all Windows 7 OEM Product Keys although they have to be manually input as they are physically printed on a paper Code of Authenticity (COA). Once the 25 Digit Product Key is manually input the installation media will select the correct corresponding Edition of Windows 10 OEM to install. The COA is often found in the battery compartment of laptops. All Activation Mechanisms with Windows 7 Keys still work despite Microsoft only marketing a 1 year free upgrade.
The Media Creation Tool is a small application which can be used to Download Windows 10 Setup Files and Create a Windows 10 .iso. The .isos created from the Windows 10 Media Creation are multi-edition and the Media Creation Tool checks the setup files before creating the installation .iso reducing installation failure via the selection of the wrong Windows Edition or from obtaining an incomplete download.

Select Create Installation Media – I always recommend creating installation media even if you plan to Upgrade this PC as it means you have installation media handy in the rare event the upgrade install fails. Select next:
By default Microsoft should automatically* select your Language, Edition and Architecture using your underlying Operating System:
* Note when run on a Windows 7 English (UK) installation, it will incorrectly select English (US) opposed to English (UK). To avoid installation of improper English (US), you will need to manually select English (UK).
To change these options, uncheck use recommended options for this PC:
Select your Language:
In this case I will select English (United Kingdom):
Note there are no options under “Edition” because the Windows 10 Version 1809 Installation .iso is multiple Edition:
The Windows 10 Version 1809 Installation ISO from the Media Creation Tool shows these Editions during Installation (without a Product Key Input). This covers most OEM and Retail licenses however the Windows 10 ISO from direct download links has the additional Pro Education (not to be confused with Pro or Education) and Pro Workstation Edition:
Select your desired architecture, in the vast majority of cases this will be 64 Bit:
Now select next:
I prefer to have the installation ISO saved and also find Rufus more reliable to make the Bootable USB. Therefore I recommend selecting ISO file and then pressing next:
Microsoft just call the .iso Windows by default, however I recommend renaming it, so it includes the version and architecture in it’s file name:
The Media Creation Tool will Download the Windows 10 Setup Files:
It’ll then verify the files it’s Downloaded:
Now it will create the installation ISO from the setup files. This means the installation ISO is created on your computer and has a unique checksum:
On the next screen it’ll give you obsolete instructions on burning the ISO file to a DVD. DVDs should never be used for Windows 10 Installation Media. Select Finish:
The Media Creation Tool will not clean up some files and then close:
Now that you have the installation .iso you can make a Bootable USB (recommended) or alternatively mount it via Windows Explorer (Windows 8 or Later) and launch the setup to perform an in place upgrade.
