This update includes quality improvements.  Key changes include:

  • Allows users to go back to a host browser from a Windows Defender Application Guard (WDAG) container.
  • Addresses an issue that causes Internet Explorer to stop responding to a browse request.
  • Addresses an issue with looping redirects between Microsoft Edge and Internet Explorer 11.
  • 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 the Palestinian Authority.
  • Addresses an issue in which the desktop wallpaper image set by a Group Policy will not update if that wallpaper image has the same name as the previous image.
  • Addresses an issue that prevents the removal of Bluetooth® peripheral devices from some systems with specific Bluetooth radios.
  • Addresses an issue with using an apostrophe or single quote character in the log entries of the Event Log Service.
  • Addresses an issue in which Windows attempts to renew Azure Active Directory (AAD) token certificates when there is no internet connectivity. This issue occurs during AAD authentication and slows the performance of applications.
  • Addresses an issue that prevents updates from downloading from a Windows Server Update Services (WSUS) server when a Windows Defender Application Control policy is set to manage which updates can be deployed.
  • Addresses an issue that disconnects a remote desktop session when you lock the session using a third-party credential provider.
  • 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 prevents ActiveX controls from automatically installing through a proxy server.
  • 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 random-access memory (RAM) capacity of a CPU (“hot add”) on a 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 that may cause an error when you attempt to access a Network File System (NFS) share.
  • Addresses an issue that may cause a server to need a restart because the system nonpaged pool consumes too much memory.
  • Addresses an issue that prevents NumLock from working properly in a Remote Assistance session when the Remote Assistance window gains and loses focus.
  • Addresses an issue with the "Allow uninstallation of language features when a language is uninstalled." Group Policy.
  • Addresses an issue in Windows Defender Application Guard (WDAG) that displays the error "0xc000026b" when a user signs out.
  • Addresses an issue that causes the Windows Event Log service to stop working when certain characters are included in an event.
  • 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
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.

To mitigate the issue, disable the Variable Window Extension on WDS server using one of the following options:

Option 1:
Open an Administrator Command prompt and type the following:

Wdsutil /Set-TransportServer /EnableTftpVariableWindowExtension:No

Option 2:
Use the Windows Deployment Services UI.

  1. Open Windows Deployment Services from Windows Administrative Tools.
  2. Expand Servers and right-click a WDS server.
  3. Open its properties and clear the Enable Variable Window Extension box on the TFTP tab.

Option 3:
Set the following registry value to 0:

“HKLM\System\CurrentControlSet\Services\WDSServer\Providers\WDSTFTP\EnableVariableWindowExtension”.

Restart the WDSServer service after disabling the Variable Window Extension.

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

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.
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.
