Windows 10: Refresh for Reliability Update KB4023057 (Nov. 2020)

[German]Microsoft has updated in Nov. 2020 Update KB4023057 for Windows 10 Update Service components for older Windows 10 versions. The update is intended to improve the transition to the Windows 10 October 2020 update (version 20H2).


November 2020 refresh for Update KB4023057

Update KB4023057 (Update for Windows 10 Update Service components) is something like a zombie, because it comes back cyclically in updated form. The updated version of the reliability update KB4023057, dated November 2020, is available for the following Windows 10 versions:

  • Windows 10 Version 1511
  • Windows 10 Version 1607
  • Windows 10 Version 1703
  • Windows 10 Version 1709
  • Windows 10 Version 1803
  • Windows 10 Version 1809
  • Windows 10 Version 1903
  • Windows 10 Version 1909
  • Windows 10 Version 2004

    Microsoft states that the update is available for all these editions of Windows 10 (which isn't correct, because an install in enterprise environments isn't intended). The description of the update is dated November 19, 2020 and states the following::

    This update contains reliability improvements to Windows Update service components in Windows 10 versions 1507, 1511, 1607, 1703, 1709, 1803, 1809, 1903, 1909, and 2004. Steps may be taken to free up disk space on your device if you do not have enough disk space to install Windows updates.

    This update contains files and resources to troubleshoot problems that affect the update processes in Windows 10 and that may prevent you from installing important Windows updates. These improvements help ensure that updates are installed seamlessly on your device and help improve the reliability and security of devices that run Windows 10.

    The text does not change significantly with each of the re-shares, but at most one new version of Windows 10 is added to which the update then applies in addition. Internally, Microsoft is probably tinkering with some compatibility rules that prevent or cause problems when updating home user versions of Windows 10.

    Important: This update is not intended for Windows 10 Enterprise and Education used in corporate environments. Therefore, this update is not distributed via WSUS.

    The update will be offered via Windows Update as well as in the Microsoft Update Catalog. There are different versions in the Microsoft Update Catalog, depending on the update date. The last version is from October 2020 and is supposed to be valid for Windows 10 version 1709. I have not (yet) found a version from November 2020.

    The update deeply interferes with the existing Windows 10 installation, cleans up update blockers set by the user, creates free space on the system drive if necessary, resets the network connection and more. In my blog post Windows 10: Update KB4023057 released (Sept. 6, 2018) I described more details about what this update does. Additionally, these details are described in the support post for update KB4023057.
