    The Start menu, Windows search, and Universal Windows Platform (UWP) apps might not work as expected or might have issues opening. Affected Windows devices might have damaged registry keys or data which might affect apps using Microsoft Office APIs to integrate with Windows, Microsoft Office, or Microsoft Outlook or Outlook Calendar. An example of an app affected by this issue is ClickShare. The underlying Issue is not caused by the installation of an update to Windows and might be exposed by an update to an affected app.

    Workaround: To mitigate this issue, you can uninstall apps which integrate with Windows, Microsoft Office, Microsoft Outlook or Outlook Calendar. Updates to affected apps or guidance from the developer of the app might also be available. If you are using ClickShare by Barco, please see Symptom: Start Menu and other shell components fail when Apps including Barco's ClickShare access Office APIs and Unresponsive Windows taskbar or user shell folder permissions issues with ClickShare App Calendar integration.

    Next steps: We are presently investigating and will provide an update in an upcoming release.

    After installing security intelligence update build 1.381.2140.0 for Microsoft Defender, application shortcuts in the Start menu, pinned to the taskbar, and on the Desktop might be missing or deleted. Additionally, errors might be observed when trying to run executable (.exe) files which have dependencies on shortcut files. Affected devices have the Atack Surface Reduction (ASR) rule "Block Win32 API calls from Office macro" enabled. After installing security intelligence build 1.381.2140.0, detections resulted in the deletion of certain Windows shortcut (.lnk) files that matched the incorrect detection pattern.

    Windows devices used by consumers in their home or small offices are not likely to be affected by this issue.

    Workaround: Changes to Microsoft Defender can mitigate this issue. The Atack Surface Reduction (ASR) rules in Microsoft Defender are used to regulate software behavior as part of security measures. Changing ASR rules to Audit Mode can help prevent this issue. This can be done through the following options:

    Microsoft Office applications can be launched through the Microsoft 365 app launcher. More details on the Microsoft 365 app launcher can be found in Meet the Microsoft 365 app launcher

    Next steps: This issue is resolved in security intelligence update build 1.381.2164.0. Installing security intelligence update build 1.381.2164.0 or later should prevent the issue, but it will not restore previously deleted shortcuts. You will need to recreate or restore these shortcuts through other methods. For additional information and help recovering missing shortcuts, see Recovering from Attack Surface Reduction rule shortcut deletions (updated on January 17, 2023 to include additional guidance and scripts to help with recovery).

    Database connections using Microsoft ODBC SQL Server driver might fail.

    Opened: 2022-12-05, 15:45 PT

    After installing KB5019959, apps which use ODBC connections utilizing the Microsoft ODBC SQL Server Driver (sqlsrv32.dll) to access databases might fail to connect. You might receive an error within the app or you might receive an error from SQL Server, such as "The EMS System encountered a problem" with "Message: [Microsoft][ODBC SQL Server Driver] Protocol error in TDS Stream" or "Message: [Microsoft][ODBC SQL Server Driver]Unknown token received from SQL Server". Note for developers: Apps affected by this issue might fail to fetch data, for example when using the SQLFetch function. This issue might occur when calling SQLBindCol function before SQLFetch or calling SQLGetData function after SQLFetch and when a value of 0 (zero) is given for the ‘BufferLength’ argument for fixed datatypes larger than 4 bytes (such as SQL_C_FLOAT).

    If you are unsure if you are using any affected apps, open any apps which use a database and then open Command Prompt (select Start then type command prompt and select it) and type the following command:

    tasklist /m sqlsrv32.dll
    

    Workaround: To mitigate this issue, you can do one of the following:

    • ​If your app is already using or able to use Data Source Name (DSN) to select ODBC connections, install Microsoft ODBC Driver 17 for SQL Server and select it for use with your app using DSN. Note: We recommend the latest version of Microsoft ODBC Driver 17 for SQL Server, as it is more compatible with apps currently using the legacy Microsoft ODBC SQL Server Driver (sqlsrv32.dll) than Microsoft ODBC Driver 18 for SQL Server.
    • ​If your app is unable to use DSN, the app will need to be modified to allow for DSN or to use a newer ODBC driver than Microsoft ODBC SQL Server Driver (sqlsrv32.dll).

    Resolution: This issue was resolved in KB5022282. If you have implemented the above workaround, it is recommended to continue using the configuration in the workaround.

    Affected platforms:

    • ​Client: Windows 11, version 22H2; Windows 10, version 22H2; Windows 11, version 21H2; Windows 10, version 21H2; Windows 10, version 21H1; Windows 10, version 20H2; Windows 10 Enterprise LTSC 2019; Windows 10 Enterprise LTSC 2016; Windows 10 Enterprise 2015 LTSB; Windows 8.1; Windows 7 SP1

    After installing KB5021233, some Windows devices might start up to an error (0xc000021a) with a blue screen. Technical note: After installing KB5021233, there might be a mismatch between the file versions of hidparse.sys in c:/windows/system32 and c:/windows/system32/drivers (assuming Windows is installed to your C: drive), which might cause signature validation to fail when cleanup occurs.

    Workaround: To mitigate this issue on devices already experiencing it, you will need to use Windows Recovery Environment (WinRE) with the following steps:

    1. ​You will need to enter Windows Recovery Environment. If your device has not automatically started up into WinRE, please see Entry points into WinRE.
    2. ​Select the Troubleshoot button.
    3. ​Select the "Start recovery, troubleshooting, and diagnostic tools" button.
    4. ​Select the "Advanced Options" button.
    5. ​Select the "Command Prompt" button and wait for your device to restart, if needed.
    6. ​Your device should restart to a Command Prompt window. You might need to sign into your device with your password before getting to the Command Prompt window.
    7. ​Run the following command (Important: If Windows is not installed to C:\windows you will need to modify the command to your environment): xcopy C:\windows\system32\drivers\hidparse.sys C:\windows\system32\hidparse.sys
    8. ​Once the previous command completes, type: exit
    9. ​Select the "Continue" button.
    10. ​Windows should now start up as expected.

    Important: It is not recommended to follow any other workaround than those recommended above. We do not recommend deleting the hidparse.sys from your Windows\System32 folder.

    Resolution: This issue was resolved in KB5022282. This update should prevent the issue from occurring. Windows devices in which this issue has already occurred will still need to follow the workaround above.

    Affected platforms:

    • ​Client: Windows 10, version 22H2; Windows 10, version 21H2; Windows 10, version 21H1; Windows 10, version 20H2

    After installing updates released September 20, 2022 or later, taskbar elements might flicker and cause system instability. Symptoms might include: 

    • ​The Weather or News and Interests widget or icons flickers on the Windows taskbar
    • ​The Windows taskbar stops responding
    • ​Windows Explorer stops responding
    • ​Applications including Microsoft Word or Excel might stop responding if they are open when the issue occurs

    Restarting the devices can alleviate the issue in some cases, but possibly not all.

    Resolution: This issue is resolved using Known Issue Rollback (KIR). KIRs are applied to most consumer (home) and non-managed devices without the need for any manual action. Please note that it might take up to 24 hours for the resolution to propagate automatically to these devices. Restarting your Windows device might help the resolution apply to your device faster. 

    Enterprise-managed devices which have installed an affected update and encountered this issue can be resolved by installing and configuring a special Group Policy. The special Group Policy can be found in Computer Configuration -> Administrative Templates -> <Group Policy name listed below>.

    Domain join operations might intentionally fail with error "0xaac (2732): NERR_AccountReuseBlockedByPolicy" and text "An account with the same name exists in Active Directory. Re-using the account was blocked by security policy."

    This issue originates with the October 2022 security updates ( KB5018410) which introduced some hardening changes enabled by default for domain join. Please see KB5020276 - Netjoin: Domain join hardening changes to understand the new designed behavior.

    Affected scenarios include some domain join or re-imaging operations where a computer account was created or pre-staged by a different identity than the identity used to join or re-join the computer to the domain.

    Home users of Windows are unlikely to experience this issue.

     

    Next steps: Please see KB5020276 to understand the designed behavior. We have added insights to this KB, and are evaluating whether optimizations can be made in a future Windows Update. This guidance will be updated once those changes have released.
