The 20H1 update of Windows 10 (probably to be called the April 2020 Update) has just received an update. The update for Windows Insiders on the slow ring takes the build of Windows 10 to 19041.84 and installs via a quick reboot.

The update includes quality and security fixes as well as fixing an issue stopping a machine from booting:

Hello Windows Insiders, today we’re releasing 20H1 Build 19041.84 (KB4539080) to Windows Insiders in the Slow ring. This Cumulative Update includes quality improvements. Key changes include:

Security updates to Microsoft Edge, Internet Explorer, Windows App Platform and Frameworks, Microsoft Graphics Component, Windows Input and Composition, Windows Media, Windows Shell, the Microsoft Scripting Engine, Windows Fundamentals, Windows Management, Windows Virtualization, Windows Peripherals, Windows Network Security and Containers, Windows Storage and Filesystems, and Windows Server.

We have fixed an issue where in certain cases, after Windows runs a scheduled task during a maintenance window, a PC may get into an unbootable state after installing Build 19041.21 (KB4535550).

The 20H1 / 2004 update has been completed for some time and will probably be released before April. You can read my full review of the Windows 10 April 2020 Update on my blog.

  1. This update is refusing to install with the error code 0x80070308

    Have tried several approaches (e.g. Dism cleanup etc) without success.
