Microsoft Issues Cumulative Update for Windows 10 Version 2004

Posted on February 12, 2020 by Paul Thurrott in Windows 10 with 6 Comments

Windows 10 version 2004 isn’t yet available to the public, but Microsoft has issued a cumulative update to the Slow ring of the Insider Preview program. Build 19041.84 (KB4539080) is a cumulative update, meaning that it includes only “quality updates,” or security and bug fixes.

Changes include:

Security updates. Microsoft Edge, Internet Explorer, the Windows App Platform and Frameworks, the 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 have all received security updates.

Bug fixes. Microsoft says it has 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).”

Curiously, there are still some known issues worth mentioning—like an incompatibility between Narrator, NVDA hardware, and the new Microsoft Edge—but then that’s why Microsoft is using this weird new release cycle: It is updating each release for a few months between the time of its completion and when it is released to the public. Based on the version number, we expect Windows 10 version 2004 to ship publicly in March or April.

    Hi Paul,

    in last paragraph first sentence - NVDA is for NIVIDA?

    Best regards,

    The update moved Edge to 80.0.361.50 (from .48) which fixes the On Startup page behavior bug.

    "Based on the version number, we expect Windows 10 version 2004 to ship publicly in March or April."

    maybe...when pigs fly, Paul.

    version 2004 more likely to get a public release towards late April or May 2020

      In reply to epguy40:

      and according to this ZDNet article by Ed Bott about Windows 10 version 2004:

      "Based on Microsoft's previous release schedules, version 2004 should be officially available to the public beginning sometime in May, with a staged rollout via Windows Update over the next six months."

    Oh man am i glad to run the enterprise version and thereby be able to postpone upgrades for 365 days. There is absolutely nothing in this release to warrant a upgrade.
