Windows 10: Update KB4023057 released (Dec. 7, 2018)

A short addendum for Windows 10 users. Microsoft has updated its reliability update KB4023057 for Windows 10 (version 1507 to 1803) and released it on December 7, 2018. Note: Article has been extended after initial release.


Some details about update KB4023057

KB4023057, re-released on December 7, 2018, is still titled 'Update to Windows 10, versions 1507, 1511, 1607, 1703, and 1709 for update reliability'. This update is available from the RTM version of Windows 10 version 1507 to version 1803 (but not for the current version 1809). This update is re-released cyclically. Microsoft writes in the KB article about the update that this brings improvements with regard to the reliability of the Windows Update Service:

This update includes reliability improvements to Windows Update Service components in Windows 10, versions 1507, 1511, 1607, 1703, 1709, and 1803. It may also take steps to free up disk space on your device if you do not have enough disk space to install Windows updates.

This update includes files and resources that address issues that affect the update processes in Windows 10 that may prevent important Windows updates from being installed. These improvements help make sure that updates are installed seamlessly on your device, and they help improve the reliability and security of devices that are running Windows 10.

This is the same text as for the September release. The only difference: In the September issue the support for version 1803 was still missing because Windows 10 V1809 was still unreleased.

Only available via Windows Update

The update is only available via Windows Update, i.e. no download from the Microsoft Update Catalog or distribution via WSUS. Can also be interpreted in this way: Business users with WSUS & Co. won't get this update – Windows 10 Home users are 'guinea pigs'. Microsoft is testing the stuff on private customers and in small companies with individual Windows 10 Pro computers. Woody Leonhard also has a few words on the update at

Some background and Update damages

The update deeply interferes with the existing Windows 10 installation, cleans user-set update blockers, creates free disk space on the system drive if necessary, resets the network connection and more. More details may be found in my blog post Windows 10: Update KB4023057 released (Sept. 6, 2018).

Update installation as app

Within this Microsoft Answers forum thread (and within dthis MS Answers forum thread) I came across the hint that update KB4023057 (at least in some variants) will be installed as an app. I looked into a virtual machine with Windows 10 Pro V1709 that was not used for a long time.

KB4023057-Installation als App


The screenshot above shows that update KB4023057 was installed on November 13, 2018 both as an app and as 'Windows Setup Remediations …'. This explains why people who blocked upgrades get this update. And it may also explain why the "Show Or Hide Updates" tool (wushowhide.diagcab) can't block this update (see Windows 10 tip: Block updates).

Issues with Update KB4023057

The details discussed within my blog post Windows 10: Update KB4023057 released (Sept. 6, 2018), explains perhaps, why some users are facing serious issues after this update has been installed.

The update also resets the network connections (and organizes, if necessary also a driver update or further actions). I had read about issues with internet connections after installing the update.

  • Within this MS Answers forum thread user davpar describes issues with his internet connection (but the post is related to an early version of this update).
  • I received some feedback to my German version of this blog post, where a user claims a slow internet connection, after installing the update. Also at is this post with a similar issue.

User davpar postet within this MS Answers forum thread a bucked of serious issues caused by previous versions of this update.

    I suspect a major reason why it is not available via the MS Update Catalog is so that it cannot be downloaded and picked apart in isolation. Just part of the cat-and-mouse game that MS now imposes upon its users and the same reason in reverse why I don't publish how I disable Windows Update completely. Remember when Windows was almost infinitely customizable and under user control – a symbiosis? Now it's more like warfare. :(

    I was force downloaded with KB4023057 on 12/7/18. The following morning I wasn't able to log on for more than 90 minutes. I got a spinner and a message "scanning and repairing volume" repairing a volume that up to that point had no issues . Now I cannot turn my machine off unless I'm willing to watch a spinner for 90minutes plus before I can log on. Attempted to remove the update from Programs & Features, it would not allow me to remove it. They have totally screwed up my computer and I have no idea how to get it back running smoothly again. This totally sucks, I bought and paid for the machine, its mine , what right do they have to mess with my property? I have Windows 10 version 1803 and its now messed up.
