Windows 10 Preview Update KB5014666 (June 28, 2022)

Windows[German]Microsoft has released an optional cumulative (preview) update KB5014666 on June 28, 2022 (D-Week). This is supposed to fix numerous bugs in Windows Server version 20H2 as well as Windows 10 version 21H1 – 21H2. In addition it brings new print functions. Below I give an overview regarding these updates for Windows 10.


The information about the updates can be found in the Windows 10 update history page. It should be noted that these updates are so-called preview updates. These are optional and must be manually triggered for download and installation by default.

Windows 10 Preview Update KB5014666

Cumulative Preview Update KB5014666  is available for Windows 10 Enterprise 20H2, Windows 10 21H1 – 21H2, and Windows Server version 20H, and bumps the builds to 19042.1806, 19043.1806, and 19044.1806. Here's the list of highlights Microsoft lists:

  • Addresses an issue that prevents the Pashto language from appearing in the language list.
  • Addresses an issue that affects the touchpad area that responds to a right-click (the right-click zone).
  • Addresses a known issue that might prevent you from using the Wi-Fi hotspot feature.

So there too, the hotspot issue is fixed as a result of the latest updates. The list of new features and fixed bugs is also quite extensive:

  • New! Adds IP address auditing for incoming Windows Remote Management (WinRM) connections in security event 4262 and WinRM event 91. This addresses an issue that fails to log the source IP address and machine name for a remote PowerShell connection.

  • New! Adds Server Message Block (SMB) redirector (RDR) specific public File System Control (FSCTL) code FSCTL_LMR_QUERY_INFO.


  • New! Introducing the following Print and Scan features:

    • IPP over USB support – Microsoft has supported Internet Print Protocol (IPP) for network printers starting in 2018 with the release of Windows 10, version 1809. We are now expanding IPP support to USB printers.

    • Print support app (PSA) APIs – Using the PSA framework, printer manufacturers can extend printer functionalities and user experience. For more information, see Print support app design guide.

    • PIN-protected printing for IPP and Universal Print – Standard print dialogs now include a user interface to enter a PIN code.

    • eSCL Mopria Scan protocol – Windows now supports the eSCL Mopria Scan protocol. It can be used with Mopria certified scanner devices.

  • Addresses an issue that affects the Cloud Clipboard service and prevents syncing between machines after a period of inactivity.

  • Addresses an issue that prevents the Pashto language from appearing in the language list.

  • Enables the InternetExplorerModeEnableSavePageAs Group Policy. For more information, see Microsoft Edge Browser Policy Documentation.

  • Addresses an issue that affects the touchpad area that responds to a right-click (the right-click zone). For more information, see Right-click zone.

  • Addresses an issue that affects some certificates chains to Root Certification Authorities that are members of the Microsoft Root Certification Program. For these certificates, the certificate chain status can be, "This certificate was revoked by its certification authority".

  • Addresses an issue that leads to a false negative when you run scripts while Windows Defender Application Control (WDAC) is turned on. This might generate AppLocker events 8029, 8028, or 8037 to appear in the log when they should not.

  • Addresses an issue that prevents the use of Encrypted File System (EFS) files over a Web-based Distributed Authoring and Versioning (WebDAV) connection.

  • Addresses an issue that causes a domain controller to incorrectly write Key Distribution Center (KDC) event 21 in the System event log. This occurs when the KDC successfully processes a Kerberos Public Key Cryptography for Initial Authentication (PKINIT) authentication request with a self-signed certificate for key trust scenarios (Windows Hello for Business and Device Authentication).

  • Addresses an issue that causes the LocalUsersAndGroups configuration service provider (CSP) policy to fail when you modify the built-in Administrators group. This issue occurs if the local Administrator account isn't specified in the membership list when you perform a replace operation.

  • Addresses an issue in which malformed XML inputs might cause an error in DeviceEnroller.exe. This prevents CSPs from being delivered to the device until you restart the device or correct the XML.

  • Addresses an issue that causes Microsoft NTLM authentication using an external trust to fail. This issue occurs when a domain controller that contains the January 11, 2022 or later Windows update services the authentication request, is not in a root domain, and does not hold the Global Catalog role. The affected operations might log the following errors:

    • The security database has not been started.

    • The domain was in the wrong state to perform the security operation.


  • Addresses an issue that affects devices enrolled in Update Compliance and have installed the April 2022 Windows non-security or later updates. For more information, see Monitor Windows Updates with Update Compliance. Devices that are enrolled in other Windows diagnostic data processor configuration programs or have a combined enrollment with any of these programs and Update Compliance are not affected.

  • Addresses a known issue that might prevent you from using the Wi-Fi hotspot feature. When attempting to use the hotspot feature, the host device might lose the connection to the internet after a client device connects.

The update is optional and is only offered when the user explicitly selects optional updates for installation in the settings page. The update can also be downloaded and installed from the Microsoft Update Catalog.  The latest Servicing Stack Update (SSU) is integrated. Microsoft lists several known issues with this update in the support article. Further details can be found in the support article in case of doubt.
