Microsoft is testing a new cumulative update for Windows 10 version 1903 with Insiders in the Release Preview Ring. If the update qualifies Microsoft’s standards, it will be pushed to all Windows 10 May 2019 Update devices later this month.

If you have subscribed to Release Preview Ring, you will receive Windows 10 Build 18362.207 (KB4501375). We don’t know what has improved with today’s update as Microsoft hasn’t published the changelog of Windows 10 May 2019 Update Build 18362.207 yet.

The company is expected to share information on fixes and improvements included in this release when the public rollout to production devices begins.

In addition to this cumulative update, a new servicing stack for Windows 10 is also being tested with Insiders. Windows 10 servicing stack update KB4506933 is available for Release Preview Ring and it is supposed to improve Windows Update reliability.

The existing known issues

The rollout of Windows 10 May 2019 Update started late last month, but the update is not available for every system because of Microsoft’s gradual rollout approach.

The software giant also maintains a list of known issues. At the moment, the known issues page lists the following problems and their mitigations:

Windows Sandbox

Windows Sandbox

Windows Sandbox is a new feature shipped with Windows 10 May 2019 Update and it allows users to run apps in an isolated environment, technically protecting the main system.

Unfortunately, Sandbox is not working on some devices and users are unable to launch Sandbox. Microsoft has promised that fix for Sandbox problem will be included in an upcoming release.

Brightness issue

Brightness setting

Microsoft is investigating another known issue in Windows 10 version 1903 where the display may not respond to brightness adjustments on Intel hardware. According to Microsoft, the brightness adjustments may not apply unless a system reboot is performed.

The company says that brightness issues will be fixed in an upcoming cumulative update.

Audio issues

Volume Flyout in Light

Microsoft is aware of another bug where the audio may not work with Dolby Atmos headphones and home theater. Microsoft is investigating this problem and the company plans to fix it in an upcoming cumulative update.
