Improvements and fixes

This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:

  • Addresses an issue that fails to set the LmCompatibilityLevel value correctly. LmCompatibilityLevel specifies the authentication mode and session security.

  • Addresses an issue that may prevent applications that use a Microsoft Jet database with the Microsoft Access 97 file format from opening. This issue occurs if the database has column names greater than 32 characters. The database fails to open with the error, “Unrecognized Database Format”.

  • Addresses an issue that prevents Microsoft Edge from loading webpages using a local IP address or a VPN connection.

  • Addresses an issue that causes the Windows Hello for Business Hybrid Key Trust deployment sign-in to fail if Windows 2019 Server domain controllers (DC) are used for authentication. The error is, "That option is temporarily unavailable. For now, please use a different method to sign in”. If Active Directory (AD) activity tracing is enabled, a Local Security Authority Subsystem Service (LSASS) exception may occur in the Windows 2019 DC when processing a user’s sign in.

    Note: The AD Data Collector Set and Microsoft Azure Advanced Threat Protection (AATP) enable Active Directory activity tracing by default.

  • Addresses an issue in Microsoft HoloLens that allows users to bypass the lock screen sign in process in some work flows.

  • Addresses an issue in Microsoft HoloLens that causes Miracast to disconnect and not reconnect when an app starts using the camera.

  • Improves the reliability of app downloads from the Microsoft Store and MDM servers while a device is in Standby for Microsoft HoloLens.

  • Improves hologram stability when using Holographic Remoting for Microsoft HoloLens.

  • Allows Kiosk mode configuration on Microsoft HoloLens without specifying a startup app.

  • Improves the reliability of Remote Assist in Microsoft HoloLens.

  • Improves Wi-Fi Connect during the out of box experience (OOBE) for Microsoft HoloLens.

  • Addresses an issue that removes secondary tiles during an upgrade for Microsoft HoloLens.

  • Allows you to skip Wi-Fi setup when using a provisioning package to configure Microsoft HoloLens.

  • Security updates to Microsoft Scripting Engine, Microsoft Edge, Windows Server, the Microsoft JET Database Engine, Internet Explorer, Windows Wireless Networking, Windows Storage and Filesystems, Windows Input and Composition, Windows Graphics, and Windows App Platform and Frameworks.
