Microsoft started the rollout of the May 2019 Update for Windows 10 yesterday. The company announced earlier this year that it would improve the upgrade functionality to give administrators more control over the installation of new feature updates for the operating system.

The functionality landed in Windows 10 version 1803 and version 1809 yesterday as well with the release of the cumulative updates KB4499183 and KB4497934.

The two preview updates for Windows 10, the official release will be on the June 2019 Patch Tuesday, June 11, 2019, introduce new features and fix certain issues.

KB4499183 KB4497934

Among the new features is support for the new upgrading behavior. Microsoft notes:

[..] we are introducing functionality that allows you to decide when to install a feature update. You control when you get a feature update while simultaneously keeping your devices up to date. Feature updates that are available for eligible devices will appear in a separate module on the Windows Update page (Settings > Update & Security > Windows Update). If you would like to get an available update right away, select Download and install now.

Windows 10 administrators who consider upgrading to the May 2019 Upgrade from Windows 10 version 1803 or 1809 may want to install the May 21 patches first. It is unclear if they are prerequisites for upgrading these systems to Windows 10 version 1903, the May 2019 Update.

The two updates are already available on Windows Update. Note that it is necessary to run a manual check for updates to install these on Windows 10 systems, and that they are previews.

In other words: these are beta releases and it is not recommended to install them on production machines.

Make sure you backup important files and the system before you start installing any updates that Microsoft throws your way.

Here are the other fixes and changes that these two updates make and introduce:

    If users are on 1803, would it be best to upgrade to 1809 first or straight to 1904?


    1. Martin Brinkmann said on May 31, 2019 at 2:36 pm

      I’d wait a month or two to give the May 2019 update some time to settle down and Microsoft some time to fix issues, and then jump straight to that version.

        Thanks Martin!

    You have to know that the KB4497934 package will prevent the OS to stop (or reboot) automatically. You should turn off the computer manually.

    i’m having a issue with 1903 i just noticed now.. my cpu voltage won’t go down. it was going at full overclock with power setting still at balanced, i changed to power saver, it down to the usual 0.96v momentarily, but now sits at 1.15v, and computer’s doing nothing.
    hope they fix that soon, anyone else here ?

    “The two preview updates for Windows 10, the official release will be on the June 2019 Patch Tuesday, June 11, 2019, introduce new features and fix certain issues.”

    Are these preview or official? Or they are official release of preview updates? Or you mean that the June official release will have new features not found in the current (preview) release?

    1. ilev said on May 22, 2019 at 5:39 pm

      These are patch C, preview updates. Will be included in June 11 CU.
