Update KB4512941 foür Windows 10 Version 1903

Cumulative Update KB4512941, released on August 30,2019, raises the OS build to 18362.329 and contains quality improvements but no new operating system functions. Microsoft specifies the following 'highlights' that the cumulative update addresses: 

• Updates an issue that prevents certain games from leveraging Spatial Audio capabilities.
• Updates an issue that fails to provide a cursor when you select a text input box using touch.
• Updates an issue that may cause the name of an unsupported application to appear as default text, such as "ms-resource:AppName/Text" in the Start menu after upgrading the operating system. 
• Updates an issue with downloading copyrighted digital media (music, TV shows, movies, and so on) from certain websites using Microsoft Edge and Internet Explorer.
• Improves the user experience and app compatibility so that more Win32 apps will work with Windows Mixed Reality.

Microsoft lists the following improvements and bug fixes.

• Addresses an issue that displays a black screen when you use Remote Desktop to connect to a machine running Windows 10, version 1903.
• Addresses an issue that may prevent the Windows Sandbox from starting with the error, "ERROR_FILE_NOT_FOUND (0x80070002)." This occurs on devices in which the operating system language is changed during the update process when installing Windows 10, version 1903. 
• Increases the number of supported interrupts per device to 512 on systems that have x2APIC enabled. 
• Addresses an issue that prevents some Trusted Platform Module (TPM) devices from being used for Next Generation Credentials. 
• Addresses an issue that causes a workstation to stop working when you sign in using an updated user principal name (UPN) (for example, changing UserN@contoso.com to User.Name@contoso.com). 
• Addresses an issue that prevents Windows Defender Advanced Threat Protection (ATP) from running automated forensic data collection when using registry-based proxy configuration. 
• Addresses an issue that prevents Windows Defender Advanced Threat Protection (ATP) from sending cyberspace events for paths beginning with \\tsclient. 
• Addresses a possible compatibility issue when Windows Defender Advanced Threat Protection (ATP) accesses case-sensitive Server Message Block (SMB) shares. 
• Addresses a rare issue that occurs when the mssecflt.sys driver takes too much space on the kernel stack. This results in the error, "STOP 0x7F: UNEXPECTED_KERNEL_MODE_TRAP", and Parameter 1 is set to "EXCEPTION_DOUBLE_FAULT." 
• Addresses an issue that leads to excessive memory utilization in Windows Defender Advanced Threat Protection (ATP). 
• Improves the detection accuracy of Microsoft Defender ATP Threat & Vulnerability Management. 
• Addresses an issue in which Windows Defender Application Control will not allow third-party binaries to be loaded from a Universal Windows Platform application. CodeIntegrity event error 3033 appears as, "Code Integrity determined that a process (<process name>) attempted to load <binary name> that did not meet the Store signing level requirements." 
• Addresses an issue that causes devices to have truncated device names when Autopilot provisioning automatically assigns a name to them. 
• Addresses an issue in which the product description of Windows Server 2019 was incorrect when queried using slmgr /dlv. 
• Addresses an issue that causes the Windows Management Instrumentation (WMI) class Win32_PhysicalMemory to report that 32 GB memory chips have a missing Capacity value. 
• Addresses an issue that prevents you from copying and pasting compound documents (formerly OLE objects) between an application that hosts the RichEdit control and other applications. 
• Addresses an issue that prevents certain games from leveraging Spatial Audio capabilities. 
• Addresses an issue that fails to provide a cursor when you select a text input element using touch. 
• Addresses an issue that may cause the name of an unsupported application to appear as default text, such as "ms-resource:AppName/Text" in the Start menu after upgrading the operating system. 
• Addresses an issue that may prevent the personal identification number (PIN) prompt from appearing when authenticating in Internet Explorer. 
• Addresses an issue with downloading digital rights management (DRM) files from certain websites using Microsoft Edge and Internet Explorer. 
• Improves the user experience and app compatibility so that more Win32 apps will work with Windows Mixed Reality. 
• Addresses an issue with LdapPermissiveModify requests, which fail to make Active Directory (AD) group membership changes if the Lightweight Directory Access Protocol (LDAP) client uses the Security Identifier (SID) syntax. In this scenario, Active Directory returns a "SUCCESS" status even though the change did not occur.
• Addresses an issue that may prevent devices from starting when they start up using Preboot Execution Environment (PXE) images from Windows Deployment Services (WDS) or System Center Configuration Manager (SCCM). The error is, "Status: 0xc0000001, Info: A required device isn't connected or can't be accessed."
• Addresses an issue that may prevent devices from starting up or cause them to continue restarting if they are connected to a domain that is configured to use MIT Kerberos realms. Domain controllers and domain members are both affected.
• Addresses an issue that may cause the following to stop responding:
  • Applications that were made using Visual Basic 6 (VB6).
  • Macros that use Visual Basic for Applications (VBA).
  • Scripts or apps that use Visual Basic Scripting Edition (VBScript).

    You may also receive an "Invalid procedure call" error.

If you go through the list of fixes, the black screen is fixed for RDP connections (see Windows 10 V1903: Remote Desktop shows Black Screen). And finally the sandbox problem is reported as fixed. Also in the status page for Windows 10 V1903 the sandbox error 0x80070002 is listed as fixed with the update KB4512941 (I couldn't check if it really is true yet). In addition, the problem with Visual Basic 6, VBA and VBScript is fixed again (see Fix for VB6, VBA, VBScript bug?). And according to the bugfix list several startup problems are fixed.

Microsoft has also released an update directly for the Windows Update Client to improve its reliability. This will be rolled out outside of Windows Update if the machine is compatible and not a LTSC variant and updates have not been blocked by GPO.

This update is optional and is automatically downloaded and installed by Windows Update if the user initiates the search for updates. This update is also available via Microsoft Update Catalog. Microsoft strongly recommends that you install the latest Service Stack Update (SSU) for your operating system before installing the latest Cumulative Update (LCU). No known issues are currently documented for the update. However, the Windows 10 V1903 status page provides a list of unfixed issues. And on the internet I found preview versions of the same build users where the installation aborted at 44% with the error code 0c800f081f (maybe caused by an image clean up after the latest update installation).

I don't know if the issues I've described in the blog post Windows 10 V1903: Updates KB4512941 and KB4515530 with the broken search and the high CPU load caused by Cortana. In the comments at deskmodder.de the high CPU load is still observed. For problems with Cortana please read the article Windows 10 V1903 Update KB4512941: Workaround for the Cortana high CPU load issue.

Update KB4515530 for Windows 10 Version 1903

The Servicing Stack Update (SSU) KB4515530 has been released on August 27, 2019. This update improves the quality of the service stack, which is the component that installs Windows updates. Some of the most important changes are: 

Fixes an uninstall problem with automated maintenance. If the Features on Demand (FOD) feature has a voice satellite installed, the feature is left in an unusable state. In addition, the shared content of the language pack will not be removed even if it is replaced.

The update is delivered via Windows Update, Microsoft Update Catalog and WSUS. Microsoft strongly recommends that you install the latest Service Stack Update (SSU) for your operating system before installing the latest Cumulative Update (LCU). Installing the Service Stack Update (SSU) ensures that the system has a robust and reliable service stack so that the systems can receive and install Microsoft security fixes.
