Applies to: Windows 10, version 1607Windows Server 2016

 

Improvements and fixes


This update includes quality improvements. Key changes include:

  • Updates wininet.dll to prevent the re-creation of File Transfer Protocol (FTP) control sessions.
  • Addresses an issue that prevents the OS from loading new icon files if it encounters an icon file that has a bad format.
  • Addresses an issue to set the date separator properly in the Japanese short date format. For more information, see KB4469068.
  • Updates time zone information for Morocco.
  • Updates time zone information for the Palestinian Authority.
  • Improves performance related to case-insensitive string comparison functions such as _stricmp() in the Universal C Runtime.
  • Addresses an issue that may cause a temporary KRB_AP_ERR_MODIFIED Kerberos sign-in failure in applications and services configured to use a Group Managed Service Account (GMSA). This issue occurs after the automatic update of the service account password.
  • Addresses an issue that causes a sign-in to fail with the error, “Incorrect Username or password” when using an empty or null password and Windows Defender Credential Guard is enabled.
  • Addresses an issue that causes Microsoft Office and other applications to prompt for a password after you change a user account password. This issue occurs on hybrid Azure Active Directory (AD) joined systems.
  • Addresses an issue with BranchCache when it is in distributed cache mode. BranchCache may use more disk space than assigned for the republication cache. To fully address the issue, devices that have exceeded the disk space assignments should empty BranchCache using the netsh branchcache flush command.
  • Addresses an issue that may cause a Stop D1 error when you increase the virtual processor count (“hot add”) on a running virtual machine.
  • Addresses an issue that may cause event 7600 in the Domain Name System (DNS) server event log to contain an unreadable server name.
  • Addresses an issue with apps that have incorrect audits and are not protected by Extranet Smart lockout when they are published using the Active Directory Federation Services (ADFS) RichClient.
  • Addresses an issue that fails to record a local user’s last logon time even when the user has accessed the server’s network share.
  • Addresses an issue that may cause error “0x7E” when moving a Network File System (NFS) File Server role and any client is active.
  • Addresses an issue with the Windows Management Instrumentation (WMI) class, Win32_PhysicalMemory, which reports 32 GB of memory without a Capacity value.
  • Addresses an issue with scrollLeft in Internet Explorer.
  • Addresses an issue that causes rendering to stop working for <svg> elements.
  • Addresses an issue that causes a delay when loading many unsigned Domain Name System (DNS) zones related to the Domain Name System Security Extensions (DNSSEC) feature. This issue occurs after configuring the following registry setting:

    Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters

    Setting: EnableFastLoadUnsignedZones

    Type: DWORD

    Value: A value of 1 enables the feature. A value of 0 disables the feature.

    Restart the operating system or the DNS server after changing the registry values.

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

Known issues in this update


Symptom Workaround

For hosts managed by System Center Virtual Machine Manager (SCVMM), SCVMM cannot enumerate and manage logical switches deployed on the host after installing the update.

Additionally, if you do not follow the best practices, a stop error may occur in vfpext.sys on the hosts.
  1. Run mofcomp on the following mof files on the affected host:
    • Scvmmswitchportsettings.mof
    • VMMDHCPSvr.mof
  2. Follow the best practices while patching to avoid a stop error in vfpext.sys in an SDN v2 environment (NC managed hosts).


 
After installing KB4467684, the cluster service may fail to start with the error “2245 (NERR_PasswordTooShort)” if the group policy “Minimum Password Length” is configured with greater than 14 characters.

Set the domain default "Minimum Password Length" policy to less than or equal to 14 characters.

Microsoft is working on a resolution and will provide an update in an upcoming release.

After installing this update, there may be issues using the Preboot Execution Environment (PXE) to start a device from a Windows Deployment Services (WDS) server configured to use Variable Window Extension. This may cause the connection to the WDS server to terminate prematurely while downloading the image. This issue does not affect clients or devices that are not using Variable Window Extension.

This issue is resolved in KB4503267.

Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.

Do one of the following:

  • Perform the operation from a process that has administrator privilege.
  • Perform the operation from a node that doesn’t have CSV ownership.
Microsoft is working on a resolution and will provide an update in an upcoming release.

After installing this update and restarting, some devices running Windows Server 2016 with Hyper-V enabled may enter Bitlocker recovery mode and receive an error, "0xC0210000".

Note Windows 10, version 1607 may also be affected when Bitlocker and Hyper-V are enabled.

For a workaround for this issue, please see KB4505821.

Microsoft is working on a resolution and will provide an update in an upcoming release.

This update may not show as applicable through WSUS or SCCM to Windows 10, version 1607 or Windows Server 2016. Also, when manually installing the standalone update from Microsoft Update Catalog, it may fail to install with the error, "The update is not applicable to your computer." The servicing stack update (SSU) (KB4498947) must be installed before installing the latest cumulative update (LCU). The LCU will not be reported as applicable until the SSU is installed. For more information, see Servicing stack updates.
Some applications may fail to run as expected on clients of Active Directory Federation Services 2016 (AD FS 2016) after installation of this update on the server. Applications that may exhibit this behavior use an IFRAME during non-interactive authentication requests and receive X-Frame Options set to DENY.

You can use the Allow-From value of the header if the IFRAME is only accessing pages from a single-origin URL. On the affected server, open a PowerShell window as an administrator and run the following command: set-AdfsResponseHeaders -SetHeaderName X-Frame-Options -SetHeaderValue "allow-from https://example.com"

Microsoft is working on a resolution and will provide an update in an upcoming release.
Internet Explorer 11 may fail to open if Default Search Provider is not set or is malformed.

To set the Default Search Provider, use the following steps:

  1. Open an Administrator Command prompt and type the following: "C:\Program Files\Internet Explorer\iexplore.exe" http://microsoft.com
  2. After Internet Explorer has opened, go to the Settings menu and select Manage add-ons.
  3. Select Search Providers in left pane.
  4. Select the link Find more search providers in the bottom left of the dialog.
  5. A new Internet Explorer window should open, allowing you to select a search provider.
  6. Select Add under the Search Provider you prefer.
  7. The Add Search Provider dialog should open, select Add.
  8. You should now be able to open Internet Explorer 11 normally.

We are working on a resolution and estimate a solution will be available in mid-June.
