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

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.
