Windows 10

After Microsoft released a series of emergency Windows 10 security updates yesterday to fix a critical vulnerability in Internet Explorer, the company has just released new optional patches for Windows 10 versions 1809 and older today. Users still running Windows 10 version 1809 (aka the October 2018 update) can download the build 17763.774 (KB4516077) today, which brings the following fixes:

  • Addresses an issue that prevents the discovery of remote systems associated with a user from working properly.
  • Addresses an issue that prevents Microsoft Narrator from opening when the User Account Controls setting is disabled on the Standard User account.
  • Addresses an issue to enable Microsoft Edge to print PDF documents that contain landscape and portrait-oriented pages correctly.
  • Addresses an issue that occasionally prevents users from changing the display brightness after resuming from Sleep or Hibernation when using certain graphics drivers.
  • Addresses an issue with MSCTF.dll that causes an application to stop working.
  • Addresses an issue that prevents some minimized windows from interacting, and you cannot restore, close, or maximize them when a system is running with a custom shell.
  • Addresses an issue that fails to provide a cursor when you select a text input element using touch.
  • Addresses an issue that causes icons in message box dialogs to appear too large when you choose scaling options in Display settings. For more information, see Using Dialog Boxes and Display Scaling in Windows 10.
  • Addresses an issue that prevents the Save and Save As options in Microsoft Office 2010 applications from working when high contrast mode is on.
  • Addresses an issue that causes File Explorer to report the number or the size of files and folders incorrectly when they use long paths.
  • Addresses an issue that causes unnecessary restart requests on servers.
  • Addresses an issue with diagnostic data processing during the Windows Out of Box Experience (OOBE) sequence.
  • Configures Windows 10 Enterprise for Virtual Desktops (EVD) editions in Azure Active Directory (Azure AD) licensing mode by default. Users who connect to EVD editions must have an EVD license.
  • Addresses an issue that prevents an 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 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 the Local Security Authority Subsystem Service (LSASS) to stop working with an “0xc0000005” error.
  • Addresses an issue that prevents the BitLocker recovery key from being successfully backed up to Azure Active Directory.
  • Addresses an issue that leads to excessive memory utilization in Microsoft Defender Advanced Threat Protection (ATP).
  • Addresses a possible compatibility issue when Microsoft 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.”
  • Improves the detection accuracy of Microsoft Defender ATP Threat & Vulnerability Management.
  • 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 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 may cause Direct Access servers to use a large amount of non-paged pool memory (pooltag: NDnd).
  • Addresses an issue that causes vertical fonts to be larger when printing to a PostScript printer.
  • Addresses an issue that prevents Windows from sending a shutdown notification to a Non-Volatile Memory Express (NVMe) drive when the driver unloads using Disable Device in Device Manager.
  • 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 in GetFinalPathNameByHandleW() that prevents Favorites from opening in Internet Explorer 11. This occurs when Favorites are redirected and offline in a client-side caching scenario with enhanced protected mode compatibility (EPM) enabled.
  • Addresses an issue in which the product description of Windows Server 2019 was incorrect when queried using slmgr /dlv.
  • 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 a Lightweight Directory Access Protocol (LDAP) runtime issue for Domain Controller Locator-style LDAP requests. The error is, “Error retrieving RootDSE attributes, data 8, v4563.”
  • Addresses an issue that causes LDAP queries that contain LDAP_MATCHING_RULE_IN_CHAIN (memberof:1.2.840.113556.1.4.1941) to intermittently fail on Windows Server 2019 domain controllers. However, these queries do not fail on domain controllers running previous versions of Windows Server.
  • Addresses an issue that causes group membership changes in Active Directory groups to fail. This occurs if the Lightweight Directory Access Protocol (LDAP) client uses the Security Identifier (SID) Distinguished Name (DN) syntax after installing previous versions of NTDSAI.DLL. In this scenario, an issue with the LdapPermissiveModify (LDAP_SERVER_PERMISSIVE_MODIFY_OID) control causes Active Directory to incorrectly return a “SUCCESS” status even though the group membership change did not occur.
  • Addresses an issue in which the Set-AdfsSslCertificate script is successful. However, it throws an exception during resource cleanup because the target server-side endpoint is no longer there.
  • 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 that may cause the Calculator app to close unexpectedly if you select any available Converter option.
  • Addresses an issue that causes excessive central processing unit (CPU) usage when users switch applications or hover over the Taskbar.
  • Addresses an issue with applications and scripts that call the NetQueryDisplayInformation API or the WinNT provider equivalent. They may fail to return results after the first page of data, often 50 or 100 entries. When requesting additional pages, you may receive the error, “1359: an internal error occurred.” This solution also resolves this issue for all the updates on or before June 18, 2019.
  • Addresses an issue with the Origin request header behavior in Internet Explorer when you make cross-origin resource sharing (CORS) requests that use redirected resources in internal subnets.
  • Addresses an issue that causes the display’s maximum brightness to appear as 50% or less after completing the out-of-box experience (OOBE) and then waking from Sleep.
  • Allows auditing of security events for clients managed by mobile device management (MDM) for security monitoring and incident response activities.
  • Addresses an issue that prevents Microsoft App-V from handling a parameter of the CreateProcess API properly, which prevents the virtual process from opening.

Be aware that Microsoft has listed 5 known issues for this update, including one causing Windows Mixed Reality Portal to display a “15-5” error code in some cases. Microsoft has provided workarounds for all these known bugs, and you can learn more details on the full release notes for this build.

For those still using Windows 10 version 1803 (or the April 2018 Update) on your PC, the build 17134.1039 (KB4516045) is now available for you with the following fixes:

  • Addresses an issue that may cause the Local Security Authority Subsystem Service (LSASS) to stop working with an “0xc0000005” error.
  • Changes the default setting for BitLocker when encrypting a self-encrypting hard drive. Now, the default is to use software encryption for newly encrypted drives. For existing drives, the type of encryption will not change.
  • Addresses an issue that prevents the BitLocker recovery key from being successfully backed up to Azure Active Directory.
  • Addresses a possible compatibility issue when Microsoft 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 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.”
