We are on the final rundown to Microsoft launching the Windows 10 19H1 branch, which will reach end users in the spring. Now is the time the company is starting to push out the last remaining features to Windows Insiders. It is also a good time to start thinking about what Windows 10 19H1 will be called.

Throughout the recent years of Windows 10, Microsoft has released its twice-annual updates in April and October. It was confirmed yesterday that Windows 10 19H1 will arrive in April. Microsoft released its newest preview on the Insider Fast Ring. The update shows 19H1 will be Windows 10 version 1903.

If you are unfamiliar with the way Microsoft numbers Windows, it is quite an easy system. The version number represents the year and month a new update is finalized. For example, Windows 10 October 2018 Update is version 1809 as it was finalized in September 2018.

Microsoft finalizes builds a few weeks before the final launch to all users. That means Windows 10 version 1903 with finalize in March and launch in April.

So, what will it be called? Over the last year, Microsoft has turned to a more professional naming method for Windows. Previously the company has been adding marketing names, such as the Anniversary Update, Creators Update, and Fall Creators Update.

April 2019 Update

Now new Windows 10 releases are more subdued, known by their month and year, such as the April 2018 Update and October 2018 Update. Using a bit of logical deduction, it stands to reason Windows 10 19H1 will be known as the Spring 2019 Update when it arrives.

It is worth pointing out this is not a guarantee. Microsoft was forced to pull the October 2018 Update a week into its launch and it did not arrive again until November. Similarly, the April 2018 Update was delayed and only just squeezed out before April turned to May.

Perhaps the company will stick with 19H1 through the release cycle.
