Quote:Microsoft has recently updated the ISO images for Windows 10 version 1903, or May 2019 Update, to include the latest security patches that the company released this month.
 
In other words, if you download the Windows 10 ISOs from Microsoft – this means you have to use either the Media Creation Tool or MSDN to get the images – you should now be able to install the May 2019 Update with the July 2019 security updates included by default.
 
The latest security patches that Microsoft published were included in cumulative update KB4507453, which was released on the July 2019 Patch Tuesday cycle. This brought the OS build number to 18362.239, so after installing Windows 10 version 1903 with the updated ISO images, this is the version you should get.

ISO images are particularly useful for clean installs and offline installation of Windows 10 version 1903, either on a single device or on entire fleets. In some cases, including when new feature updates are released, starting from scratch could help deal with bugs in the operating system, especially when compatibility glitches are involved.
