When a client connects to the server to install the printer, a directory mismatch occurs, which causes the installer files to generate incorrectly. As a result, the drivers may not download.**Note** The printer connection methods described in this issue are not commonly used by devices designed for home use.

This issue occurs because of a reference count issue in the **DFS.SYS** driver during cluster failover. As a result, the system might become unresponsive.\n * Addresses an issue with using the **robocopy **command with the backup option (**/B**) to fix copy failures. This issue occurs when the source files contain Alternate Data Streams (ADS) or Extended Attributes (EA) and the destination is an Azure Files share.\n * Addresses an issue that causes Authentication Mechanism Assurance (AMA) to stop working. This issue occurs when you migrate to Windows Server 2016 (or newer versions of Windows) and when using AMA in conjunction with certificates from Windows Hello for Business.\n * Addresses an issue that prevents you from writing to a Windows Management Instrumentation (WMI) repository after a low memory condition occurs.\nIf you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.

After about 20 minutes, you should be able to restart your device and not encounter this issue. \nFor more information about the specific errors, cause, and workaround for this issue, please see KB5003571. \nAfter installing this update, devices which attempt to connect to a network printer for the first time might fail to download and install the necessary printer drivers. Devices which had connected to and installed the printer prior to the installation of KB5005568 are unaffected and operations to that printer will succeed as usual.This issue has been observed in devices which access printers via a print server using HTTP connections. When a client connects to the server to install the printer, a directory mismatch occurs, which causes the installer files to generate incorrectly. As a result, the drivers may not download.**Note** The printer connection methods described in this issue are not commonly used by devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.| This issue is resolved in KB5005625 \nAfter installing this or a later update, installation of printers using Internet Printing Protocol (IPP) might not complete successfully. Devices which had connected to and installed the printer prior to the installation of KB5005568 are unaffected and print operations to that printer will succeed as usual.**Note** IPP is not commonly used by devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.| This issue is resolved in KB5006744. \nAfter installing KB5005102, Windows Server 2019 virtual machines (VMs) employing Software Defined Networks (SDN) or traditional multi-tenant RRAS gateways may lose connectivity with external networks using Gateway connections. Installing the August preview or later update will not affect Windows Server 2019 hosts, Network Controller VMs, and Software Load Balancer VMs.| This issue is resolved in KB5006672. \nAfter installing this update on a print server, printing properties defined on that server might not be correctly provided to clients. Note this issue is specific to print servers and does not impact standard network printing. This issue will not cause printing operations to fail, however, custom settings defined on the server \u2013 for example, duplex print settings \u2013 will not be applied automatically, and clients will print with default settings only.This issue results from an improper building of the data file which contains the printer properties. Clients which receive this data file will not be able to use the file content and will instead proceed with default printing settings. Clients who have previously received the settings package prior to the installation of KB5005625 are unaffected. Servers which use default print settings and have no custom settings to provide to clients are unaffected.**Note** The printer connection methods described in this issue are not commonly used by devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.| This issue is resolved in KB5006672. \nAfter installing this update, you might receive a prompt for administrative credentials every time you attempt to print in environments in which the print server and print client are in different times zones.**Note** The affected environments described in this issue are not commonly used by devices designed for home use. The printing environments affected by this issue are more commonly found in enterprises and organizations.| This issue is resolved in KB5006672. \nAfter installing updates released April 22, 2021 or later, an issue occurs that affects versions of Windows Server that are in use as a Key Management Services (KMS) host. Client devices running Windows 10 Enterprise LTSC 2019 and Windows 10 Enterprise LTSC 2016 might fail to activate. This issue only occurs when using a new Customer Support Volume License Key (CSVLK). **Note** This does not affect activation of any other version or edition of Windows. Client devices that are attempting to activate and are affected by this issue might receive the error, \"Error: 0xC004F074. The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information.\"Event Log entries related to activation are another way to tell that you might be affected by this issue. Open **Event Viewer **on the client device that failed activation and go to **Windows Logs **&gt; **Application**. If you see only event ID 12288 without a corresponding event ID 12289, this means one of the following:\n\n * The KMS client could not reach the KMS host.\n * The KMS host did not respond.\n * The client did not receive the response.\nFor more information on these event IDs, see [Useful KMS client events - Event ID 12288 and Event ID 12289](<https://docs.microsoft.com/windows-server/get-started/activation-troubleshoot-kms-general#event-id-12288-and-event-id-12289>).| This issue is resolved in KB5009616. \n \n## How to get this update\n\n**Before installing this update**Microsoft now combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU).

Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.\n\n## Known issues in this update\n\n### \n\n__\n\nClick or tap to view the known issues\n\n**Symptom**| **Workaround** \n---|--- \nDevices with Windows installations created from custom offline media or custom ISO image might have [Microsoft Edge Legacy](<https://support.microsoft.com/en-us/microsoft-edge/what-is-microsoft-edge-legacy-3e779e55-4c55-08e6-ecc8-2333768c0fb0>) removed by this update, but not automatically replaced by the new Microsoft Edge. This issue is only encountered when custom offline media or ISO images are created by slipstreaming this update into the image without having first installed the standalone servicing stack update (SSU) released March 29, 2021 or later.**Note **Devices that connect directly to Windows Update to receive updates are not affected. This includes devices using Windows Update for Business. Any device connecting to Windows Update should always receive the latest versions of the SSU and latest cumulative update (LCU) without any extra steps. | To avoid this issue, be sure to first slipstream the SSU released March 29, 2021 or later into the custom offline media or ISO image before slipstreaming the LCU. To do this with the combined SSU and LCU packages now used for Windows 10, version 20H2 and Windows 10, version 2004, you will need to extract the SSU from the combined package. Use the following steps to extract the SSU:\n\n 1. Extract the cab from the msu via this command line (using the package for KB5000842 as an example): **expand Windows10.0-KB5000842-x64.msu /f:Windows10.0-KB5000842-x64.cab &lt;destination path&gt;**\n 2. Extract the SSU from the previously extracted cab via this command line: **expand Windows10.0-KB5000842-x64.cab /f:* &lt;destination path&gt;**\n 3. You will then have the SSU cab, in this example named **SSU-19041.903-x64.cab**. Slipstream this file into your offline image first, then the LCU.\nIf you have already encountered this issue by installing the OS using affected custom media, you can mitigate it by directly installing the [new Microsoft Edge](<https://www.microsoft.com/edge>). If you need to broadly deploy the new Microsoft Edge for business, see [Download and deploy Microsoft Edge for business](<https://www.microsoft.com/edge/business/download>). \nAfter installing the June 21, 2021 (KB5003690) update, some devices cannot install new updates, such as the July 6, 2021 (KB5004945) or later updates. You will receive the error message, \"PSFX_E_MATCHING_BINARY_MISSING\".| For more information and a workaround, see KB5005322. \nAfter installing this update, devices which attempt to connect to a network printer for the first time might fail to download and install the necessary printer drivers. Devices which had connected to and installed the printer prior to the installation of KB5005565 are unaffected and operations to that printer will succeed as usual.This issue has been observed in devices which access printers via a print server using HTTP connections.

When it was first discovered it was only being used in a limited number of attacks, however this quickly changed once instructions for exploiting the vulnerability were published online. This vulnerability was severe enough to warrant publishing patches for older operating systems including Windows 7, Windows Server 2008 R2, and Windows Server 2008. Now that updates have been published for this vulnerability they should be applied as soon as possible.\n\n### Windows DNS Local Elevation of Privilege ([CVE-2021-36968](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-36968>))\n\nThis is the second publicly disclosed vulnerability updated this month. While the details surrounding this CVE are sparse, we do know that Microsoft has not detected exploitation in the wild. \n\n### Updates to PrintNightmare ([CVE-2021-1678](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-1678>))\n\nMicrosoft has made additional patches available for older operating systems.
