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. The printing environments affected by this issue are more commonly found in enterprises and organizations.| This issue is resolved in KB5006746. \nIT admins| Installation of printers using Internet Printing Protocol (IPP) might not complete successfully.**Note **IPP is 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 KB5006746. \nIT admins| Printing properties defined on a 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. 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. The printing environments affected by this issue are more commonly found in enterprises and organizations.| This issue is resolved in KB5006746. \nIT admins| 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 KB5006746. \nIT admins| After installing this update, Windows print clients might encounter the following errors when connecting to a remote printer shared on a Windows print server:\n\n * 0x000006e4 (RPC_S_CANNOT_SUPPORT)\n * 0x0000007c (ERROR_INVALID_LEVEL)\n * 0x00000709 (ERROR_INVALID_PRINTER_NAME)\n**Note** The printer connection issues described in this issue are specific to print servers and are not commonly observed in devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.| This issue is resolved in KB5007262. \nAll users| After installing Windows 11, some image editing programs might not render colors correctly on certain high dynamic range (HDR) displays. This is frequently observed with white colors, which could display in bright yellow or other colors.This issue occurs when certain color-rendering Win32 APIs return unexpected information or errors under specific conditions. Not all color profile management programs are affected, and color profile options available in the Windows 11 Settings page, including Microsoft Color Control Panel, are expected to function correctly.| This issue is resolved in KB5008353. \nAll users| Recent emails might not appear in the search results of the Microsoft Outlook desktop app. This issue is related to emails that have been stored locally in a PST or OST files. It might affect POP and IMAP accounts, as well as accounts hosted on Microsoft Exchange and Microsoft 365. If the default search in the Microsoft Outlook app is set to server search, the issue will only affect the advanced search.| This issue is resolved in KB5010386. \nAll users| When attempting to reset a Windows device with apps that have folders with [reparse data](<https://docs.microsoft.com/windows/win32/fileio/reparse-points>), such as OneDrive or OneDrive for Business, files which have been downloaded or synced locally from OneDrive might not be deleted when selecting the \u201cRemove everything\u201d option. This issue might be encountered when attempting a [manual reset initiated within Windows](<https://support.microsoft.com/windows/recovery-options-in-windows-31ce2444-7de3-818c-d626-e3b5a3024da5#bkmk_win11_reset_pc>) or a remote reset. Remote resets might be initiated from Mobile Device Management (MDM) or other management applications, such as [Microsoft Intune](<https://docs.microsoft.com/mem/intune/remote-actions/device-fresh-start>) or third-party tools. OneDrive files that are \u201ccloud only\u201d or have not been downloaded or opened on the device are not affected and will not persist, as the files are not downloaded or synced locally.**Note** Some device manufacturers and some documentation might call the feature to reset your device, \"Push Button Reset\", \"PBR\", \"Reset This PC\", \"Reset PC\", or \"Fresh Start\".| This issue was addressed in KB5011493. Some devices might take up to seven (7) days after the installation of KB5011493 to fully address the issue and prevent files from persisting after a reset. For immediate effect, you can manually trigger Windows Update Troubleshooter using the instructions in [Windows Update Troubleshooter](<https://support.microsoft.com/windows/windows-update-troubleshooter-19bc41ca-ad72-ae67-af3c-89ce169755dd>). If you are part of an organization that manages devices or prepared OS images for deployment, you can also address this issue by applying a compatibility update for installing and recovering Windows. Doing that makes improvements to the \"safe operating system\" (SafeOS) that is used to update the Windows recovery environment (WinRE). You can deploy these updates using the instructions in [Add an update package to Windows RE](<https://docs.microsoft.com/windows-hardware/manufacture/desktop/add-update-to-winre?view=windows-11>) using [KB5012414](<https://support.microsoft.com/help/5012414>) for Windows 11 (original release).**Important **If devices have already been reset and OneDrive files have persisted, you must use a workaround above or perform another reset after applying one of the workarounds above. \nIT admins| Universal Windows Platform (UWP) apps might not open on devices that have undergone a Windows device reset. This includes operations that were initiated using Mobile Device Management (MDM), such as Reset this PC, Push-button reset, and Autopilot Reset. UWP apps you downloaded from the Microsoft Store are not affected. Only a limited set of apps are affected, including:\n\n * App packages with framework dependencies\n * Apps that are provisioned for the device, not per user account.\nThe affected apps will fail to open without error messages or other observable symptoms. They must be re-installed to restore functionality.| This issue is addressed in KB5015882 for all releases starting October 12, 2021 and later. \n \n## How to get this update\n\n**Before installing this update**Microsoft 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/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 KB5005565, 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 KB5005565 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 KB5006738. \nAfter installing this update, when connecting to devices in an untrusted domain using Remote Desktop, connections might fail to authenticate when using smart card authentication. You might receive the prompt, \"Your credentials did not work. The credentials that were used to connect to [device name] did not work. Please enter new credentials.\" and \"The login attempt failed\" in red.| This issue is addressed in KB5007253. \nAfter installing this update, Windows print clients might encounter the following errors when connecting to a remote printer shared on a Windows print server:\n\n * 0x000006e4 (RPC_S_CANNOT_SUPPORT)\n * 0x0000007c (ERROR_INVALID_LEVEL)\n * 0x00000709 (ERROR_INVALID_PRINTER_NAME)\n**Note** The printer connection issues described in this issue are specific to print servers and are not commonly observed in devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.| This issue is resolved in KB5007253. \nWhen attempting to reset a Windows device with apps that have folders with [reparse data](<https://docs.microsoft.com/windows/win32/fileio/reparse-points>), such as OneDrive or OneDrive for Business, files which have been downloaded or synced locally from OneDrive might not be deleted when selecting the \u201cRemove everything\u201d option. This issue might be encountered when attempting a [manual reset initiated within Windows](<https://support.microsoft.com/windows/recovery-options-in-windows-31ce2444-7de3-818c-d626-e3b5a3024da5#bkmk_win11_reset_pc>) or a remote reset. Remote resets might be initiated from Mobile Device Management (MDM) or other management applications, such as [Microsoft Intune](<https://docs.microsoft.com/mem/intune/remote-actions/device-fresh-start>) or third-party tools. OneDrive files that are \u201ccloud only\u201d or have not been downloaded or opened on the device are not affected and will not persist, as the files are not downloaded or synced locally.**Note** Some device manufacturers and some documentation might call the feature to reset your device, \"Push Button Reset\", \"PBR\", \"Reset This PC\", \"Reset PC\", or \"Fresh Start\".| This issue was addressed in KB5011487. Some devices might take up to seven (7) days after the installation of KB5011487 to fully address the issue and prevent files from persisting after a reset. For immediate effect, you can manually trigger Windows Update Troubleshooter using the instructions in [Windows Update Troubleshooter](<https://support.microsoft.com/windows/windows-update-troubleshooter-19bc41ca-ad72-ae67-af3c-89ce169755dd>). If you are part of an organization that manages devices or prepared OS images for deployment, you can also address this issue by applying a compatibility update for installing and recovering Windows. Doing that makes improvements to the \"safe operating system\" (SafeOS) that is used to update the Windows recovery environment (WinRE). You can deploy these updates using the instructions in [Add an update package to Windows RE](<https://docs.microsoft.com/windows-hardware/manufacture/desktop/add-update-to-winre?view=windows-10>) using [KB5012419](<https://support.microsoft.com/help/5012419>) for Windows 10, version 21H2, Windows 10, version 21H1, and Windows 10, version 20H2.**Important **If devices have already been reset and OneDrive files have persisted, you must use a workaround above or perform another reset after applying one of the workarounds above. \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). For general information about SSUs, see [Servicing stack updates](<https://docs.microsoft.com/windows/deployment/update/servicing-stack-updates>) and [Servicing Stack Updates (SSU): Frequently Asked Questions](<https://support.microsoft.com/topic/servicing-stack-updates-ssu-frequently-asked-questions-06b62771-1cb0-368c-09cf-87c4efc4f2fe>).Prerequisite:For Windows Server Update Services (WSUS) deployment or when installing the standalone package from Microsoft Update Catalog:If your devices do not have the May 11, 2021 update (KB5003173) or later LCU, you **must **install the special standalone August 10, 2021 SSU (KB5005260).**Install this update****Release Channel**| **Available**| **Next Step** \n---|---|--- \nWindows Update and Microsoft Update| Yes| None.

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.
