Microsoft is finally rolling out Windows 10 version 1903 to millions of compatible PCs. The company has also published Windows 10 May 2019 Update ISO files and you can use the package to upgrade your PC.

You can also download ISOs of Windows 10 May 2019 Update (version 1903) to perform a clean installation. A clean installation is the best option to remove everything from the local drive including apps and settings. It allows you to start from scratch and as well as address performance or other issues.

With ISO files, you can install the operating system on multiple devices without the need to re-download it. You can also upgrade your PC directly from the ISO, or create a bootable USB drive.

It’s important to understand that Microsoft doesn’t offer ISO files directly on its website if you access the download page from a Windows 10 device. You’re only given the choice between Update Assistant or Media Creation Tool.

Update Assistant is an update management tool designed to download updates automatically and manage the timing of updates. On the other hand, Media Creation Tool can help you create a bootable USB drive with Windows 10 installation media. Both applications won’t offer you direct access to ISO packages.

Fortunately, there is a trick that will allow you to directly download Windows 10 version 1903 ISO files.

Wrapping up

Windows 10 May 2019 Update was launched yesterday and Microsoft has said that it will take a new measured and throttled approach towards the rollout. It means that the PC won’t upgrade itself automatically and surprise you with new changes.

The update will show up when you’ll check for updates, but the download won’t begin unless you click on ‘Download and install’ button.

Windows 10 version 1903 introduces multiple improvements for Windows Update and more. One of the handy features is an update icon that lives in your taskbar to remind you when future updates are available for installation.

It’s worth noting that this new version of Windows 10 is not as ambitious as previous versions. The important features are Windows Sandbox, new light theme, support for Kaomoji and more.

If you dig deeper, you might find some other handy capabilities such as a brightness slider on Action Center, an improved Focus Assist feature and a better way to deal with DPI issues.
