Microsoft has just announced the release of the Windows 10 build 19041.264 for Windows Insiders in the Slow and Release Preview rings. This is likely the first Patch Tuesday Update for Windows 10 version 2004 (20H1), which is now expected to start rolling out in the last week of May.

This new build fixes a couple of issues affecting the Windows Mixed Reality Portal, Disk Cleanup, as well as daylight saving time (DST) for users in Morocco. You can check the full release notes below:

  • We have fixed a performance issue in Windows Mixed Reality (WMR) that prevents it from working correctly for many users.
  • We fixed an issue that prevents cleaning tools, such as Disk Cleanup, from removing previously installed updates.
  • We have updated the 2020 start date for daylight saving time (DST) in the Kingdom of Morocco. For more information, see KB4557900.
  • Security updates to Internet Explorer, the Microsoft Scripting Engine, Windows App Platform and Frameworks, Microsoft Graphics Component, Windows Input and Composition, Windows Media, Windows Shell, Microsoft Xbox, Microsoft Edge, Windows Fundamentals, Windows Cryptography, Windows Authentication, Windows Kernel, Windows Virtualization, Windows Update Stack, Windows Core Networking, Internet Information Services, Windows Network Security and Containers, Windows Active Directory, Windows Server, and the Microsoft JET Database Engine.

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.

For more information about the resolved security vulnerabilities, please refer to the Security Update Guide.

Important note about accessibility 

We are aware Narrator and NVDA users that seek the latest release of Microsoft Edge based on Chromium may experience some difficulty when navigating and reading certain web content. Narrator, NVDA and the Edge teams are aware of these issues. Users of legacy Microsoft Edge will not be affected. NVAccess has released a NVDA 2019.3 that resolves the known issue with Edge.

The Redmond giant has yet to announce the release date for the Windows 10 May 2020 Update, but according to a recent post about the updated Driver Shiproom Schedule for this year, it could ship between May 26 and May 28. We’ll let you know once we get more information from Microsoft but in the meantime, the company also announced today that developers can now download the Windows 10 SDK for the May 2020 Update, which is now available with a go-live license.
