Today is the second Tuesday of the month, which is when Microsoft releases new “Patch Tuesday” updates for all supported version of Windows. For those of you already running Windows 10 version 1809, you should now be seeing the build 17763.316 (KB4487044) in Windows Update.

Here are all the fixes included in this cumulative update:

  • 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 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.
  • 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.

The release notes for this new build mention a single known issue that was already present in the previous build. This bug can cause some webpages to not load in Microsoft Edge when using a local IP addess, and Microsoft says that it’s still working on a fix that will ship in an upcoming release.

If you’re still running Windows 10 version 1803, you should now be able to download the 17134.590 (KB4487017). This cumulative update has the same known issue affecting the build 17763.316, but it comes with the following fixes:

  • 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”.
  • Adds top-level domain support to HTTP Strict Transport Security (HSTS) Preload for Microsoft Edge and Internet Explorer 11.
  • Addresses an issue that prevents Microsoft Edge from connecting using an IP address.
  • Security updates to Microsoft Scripting Engine, Internet Explorer, Windows App Platform and Frameworks, Windows Graphics, Windows Input and Composition, Microsoft Edge, Microsoft Scripting Engine, Windows Storage and Filesystems, Windows Server, and the Microsoft JET Database Engine.

In case you’re running older versions of Windows 10, there are also new cumulative updates for the versions 1709, 1703, and 1607. We invite you to check the dedicated pages on Microsoft’s Windows support website for more details.
