windows 10 1903 features


Windows 10 1903, or Windows 10 H1 as new releases are commonly called now, was released on May 21, 2019.

Windows 10 follows Microsoft’s evergreen approach of continuously releasing new updates during the year.

Included in this release, are quite a few updates, both for the users as well as for the IT Pros.

In this blog post, I will walk through the features and news in the newest Windows 10 that I think are the most important. I will therefore not cover all news, as that can be found on Microsoft’s official site.

Known issues in Windows 10 1903

Features in Windows 10 1903

Windows as a Service (WaaS)

Starting with Windows 10 1903, the Semi-Annual Channel Targeted release has been removed, giving just one version to keep track of, apart from Long-Term Servicing Channel (LTSC).

I think this is a good approach as it simplifies many things for the customers.

From my work as a consultant, I have not seen many customers implement a proper Windows as a Service plan.

Those who have created so-called Service Plans in SCCM will need to rethink their approach, as this automation will not work in the same way moving forward.

I am assuming that Microsoft will also change this in a future release of SCCM.

Windows 10 1903 can now adjust the active hours based on usage history. This is helpful when deploying new Feature Updates to users.

Improved update orchestration

Built-in intelligence which, much like the Intelligent Active Hours, installs updates based on when the user is using the machine.

Setup Diag

This tool is now included in Windows 10 1903 for troubleshooting installation issues with new updates.

User Features in Windows 10 1903

One of the main letdowns from my point of view was that the Chromium Edge Browser or “Chredge” was not let out of its Preview state. I was hoping that the reason for Microsoft delaying the release was to include it in the release.

Edge Chromium

One of the biggest news this year was Microsoft’s decision to move to a Chromium-based browser. What this means is that Edge will now behave very similar to Google Chrome. Most of the users I have talked to have not seen the difference.

The new Edge browser is currently in Preview.

Light theme

Starting with Windows 10 1903, apart from the standard Windows 10 theme, Microsoft also provides a light theme.

Focus assist

Are you getting distracted during your work hours by annoying popups? There is currently a strong trend among companies to remove distractions distracting devices.

Focus Assist helps the user by removing notifications, thereby increasing productivity.

Features for IT Pros in Windows 10 1903

One of the main reasons why many system administrators deploy a new version of Windows is that they personally see some benefit of it.

Most administrators don’t care as much about the end-users as they might think.

The Microsoft Security Baseline can be found here.

Some new features include:

  • Reserved disk space for Feature Updates
  • Windows Sandbox

Reserved disk space for Feature Updates

One big hassle when deploying Feature Updates to machines is that they take up quite an amount of disk space. You can minimize this by using Express Updates, which Microsoft Update handles by default.

One thing I wonder here is if it’s going to be an issue with machines with a smaller HDD.

Windows Sandbox

It will now be possible to test-run applications in an isolated environment within Windows 10.

Learn more on how to enable Windows Sandbox using Powershell on Niclas Anderson’s blog.

Windows Virtual Desktop

Windows Virtual Desktop is an Azure service and will now be in Public Preview. Read more about Windows Virtual Desktop here.

How to deploy Windows 10 1903

Windows Update

You can install Windows 10 1903 using Microsoft Update.


There are several ways in which you can deploy the Windows 10 update.

Feature Update

If you want to deploy Windows 10 1903 using SCCM, you should first upgrade to SCCM 1906. One reason for this is that you will need to select a new Product:

You can use the Windows 10 Configuration Baseline that I have previously completed.

In-place upgrade

You can also use an In-Place Upgrade Task Sequence which gives some extra flexibility.
