Microsoft today is rolling out an optional cumulative update for Windows 10 version 1903. It comes in the form of KB4517511 and includes a ton of fixes.

Microsoft today released a new cumulative update for Windows 10 version 1903 aka “May 2019 Update” in the form of KB4517511. Earlier this week the company rolled out cumulative updates of Windows 10. However, version 1903 was not included. In addition, Microsoft released a patch for an IE security vulnerability for Windows 10. Today’s update contains a lengthy list of fixes and improvements and is available to download now.

KB4517511 for Windows 10 1903

After installing KB4517211 your build will be bumped to 18362.387 and it includes the following fixes:

  • Addresses an issue that causes vertical fonts to be larger when printing to a PostScript printer.
  • Addresses an issue that causes printing from 32-bit applications to fail with an “Access is denied” error when you select Run as different user for the application.
  • Addresses an issue that may give write access to a removable USB disk when a user switches from a privileged user to an unprivileged user.
  • Addresses an issue that causes the lsass.exe service to stop working, which causes the system to shut down. This occurs when migrating Data Protection API (DPAPI) credentials using dpapimig.exe with the –domain option.
  • Addresses an issue that gives a Windows Hello for Business user two certificates for authentication during certificate renewal instead of one certificate.
  • Addresses an issue that prevents a web browser from connecting securely to Windows Server. This occurs when using a client authentication certificate, such as a SHA512-based certificate, and the web browser does not support a signature algorithm that matches the certificate.
  • Addresses an issue that may cause authentication to fail for certificate-based authentication when the certificate authentication includes a cname as part of the pre-authentication request.
  • Addresses an issue that prevents a Microsoft App-V application from opening and displays a network failure error. This issue occurs under certain circumstances, such as when a system’s battery is low or there is an unexpected power failure.
  • Addresses an issue that causes a query request of the Win32_LogonSession class for the StartTime to display the value of the epoch (for example, 1-1-1601 1:00:00) instead of the actual logon time. This occurs when a user who isn’t an administrator creates the query request.
  • Addresses an issue that causes File Explorer to show a regular file icon for files marked with FILE_ATTRIBUTE_OFFLINE instead of the expected placeholder icon.
  • Addresses an issue with intermittent virtual private network (VPN) disconnections on cellular networks.
  • Addresses an issue that may cause audio playback and recording to fail when connecting to a remote virtual machine.
  • Addresses an issue with MSCTF.dll that causes an application to stop working.
  • Addresses an issue with the input and display of special characters that occurs when an app uses imm32.dll.
  • Addresses an issue with resizing Windows Presentation Foundation (WPF) applications; they may not respond to being resized using the mouse until you release the mouse button.
  • Addresses an issue that may prevent older systems from upgrading to the latest operating systems because of an error in the display driver of older versions.
  • Addresses an issue that may cause the screen color to turn white on laptops that have built-in, high-dynamic-range (HDR) screens.
  • Addresses an issue with converting an application from 32-bit to 64-bit architecture.
  • Addresses an issue that prevents you from running the Active Directory Diagnostics Data Collector Set from the Performance Monitor for Domain Controllers. This causes the Data Collector Set name to appear empty. Running the Active Directory Diagnostics Data Collector Set returns the error, “The system cannot find the file specified.” Event ID 1023 is logged with the source as Perflib and the following messages:
    • “Windows cannot load the extensible counter DLL “C:\Windows\system32\ntdsperf.dll.”
    • “The specified module could not be found.”
  • Addresses an issue that causes audio in certain games to be quieter or different than expected.
  • Addresses an issue that prevents Microsoft App-V from handling a parameter of the CreateProcess API properly, which prevents the virtual process from opening.
  • Addresses an issue in which the maximum central processing unit (CPU) performance is not enabled when you select the High Performance power plan.
  • Provides a way to configure the read buffer size. This allows you to address an issue with slow upload times when uploading a file to a Universal Naming Convention (UNC) share using the Internet Information Services (IIS) Web Distributed Authoring and Versioning (WebDAV) feature.
  • Addresses an issue that causes a device to stop working when opening files from a network drive that has client-side caching enabled. This issue may occur when the device has certain third-party antivirus products installed and the drive is backed by a server that is not a Microsoft Server Message Block (SMB) server. The error code is, “0x27 RDR_FILE_SYSTEM.”
  • Facilitates the configuration of devices that are managed by mobile device management (MDM) settings, which are created by ADMX ingestion. You can update a previously ingested ADMX file with a newer version, and you are not required to delete the previous ADMX file. This solution applies to all applications that use ADMX ingestion.

Today’s update is optional and will not install automatically. But if you want to stay on top of things head to Settings > Update & security > Windows Update and check. Or, you can manually download it from the Windows Update Catalog.

There are a few known issues so make sure to read Microsoft’s release notes for all fixes, issues, and workarounds.
