Microsoft has released the Windows 11 KB5006674 cumulative update, marking it as the first update for the new operating system since it has been released to the public channel.

The KB5006674 cumulative update contains security updates, performance improvements, and bug fixes for Windows 11 21H2 since it was first released on October 5th.

You can install this update by going to Start > Settings > Windows Update and clicking on 'Check for Updates.'

What's new in the Windows 10 KB5006674 update​

After installing the KB5006674 update, Windows 11 will have its build number changed to 22000.258.

The only fixes noted in this cumulative are for compatibility issues with the Intel "Killer" and Dell "SmartByte" network optimization software.

Last week, Microsoft announced compatibility holds preventing Windows 11 upgrades on devices with these applications installed.

"Addresses known compatibility issues between some Intel “Killer” and “SmartByte” networking software and Windows 11 (original release). Devices with the affected software might drop User Datagram Protocol (UDP) packets under certain conditions. This creates performance and other issues for protocols based on UDP," explains Microsoft in the KB5006674 support bulletin

"For example, some websites might load slower than others on the affected devices, which might cause videos to stream slower in certain resolutions. VPN solutions based on UDP might also be slower."

Microsoft fixed these compatibility issues in a security update released today.

Microsoft also states that they made improvements to the servicing stack, which is used to resolve bugs or issues preventing Windows updates from properly being installed.

You can find a complete list of improves and fixes and detailed explanations of the known issues in the KB5006674 support bulletin.

Hello Windows Insiders, today we’re releasing Windows 11 Build 22000.282 to Windows Insiders in the Beta and Release Preview Channels.

This update includes the following improvements:
  • We fixed an L3 caching issue that might affect performance in some applications on devices that have AMD Ryzen processors after upgrading to Windows 11 (original release).
  • We fixed an issue for a small number of users that prevents the Start menu from working and prevents you from seeing the updated taskbar design after upgrading to Windows 11 (original release).
  • We fixed a race condition that occurs during the early part of startup that might cause a stop error.
  • We fixed a regression that might cause stop error 0x38 on some machine configurations that use non-ASCII text in the registry.
  • We fixed an issue with the interrupt handling of certain processors that might cause devices to stop responding.
  • We fixed an issue that causes PowerShell to create an infinite number of child directories. This issue occurs when you use the PowerShell Move-Item command to move a directory to one of its children. As a result, the volume fills up and the system stops responding.
  • We fixed an issue that causes the Server Manager application to disappear after you use it to remove Hyper-V features. This issue occurs when you install Server Manager on Windows 11 (original release) clients using Remote Server Administration Tools (RSAT).
  • We fixed a threading issue that might cause the Windows Remote Management (WinRM) service to stop working when it is under a high load.
  • We fixed an issue that causes the Windows Management Instrumentation (WMI) provider host process to stop working. This occurs because of an unhandled access violation that occurs when using the Desired State Configuration (DSC).
  • We fixed an issue that causes a device to stop responding when you forcibly shut down the device while a Group Policy is being updated.
  • We fixed an issue that causes file migration between Distributed File System (DFS) paths that are stored on different volumes to fail. This issue occurs when you implement the migration using PowerShell scripts that use the Move-Item command.
  • We fixed an issue that prevents you from writing to a WMI repository after a low memory condition occurs.
  • We fixed an issue with a hardcoded font in the PowerShell shortcut file that distorts Japanese, Chinese, and Korean language fonts. This update fixed this issue for all newly created users on the machine. Existing users can use the C:\Users\Default\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Windows PowerShell\Windows PowerShell.lnk file to open PowerShell to address the issue. Alternatively, existing users can create a shortcut to this file on the desktop and use the shortcut to open PowerShell.
  • We fixed an issue with parsing time formats in events when milliseconds are excluded.
  • We fixed an issue that incorrectly renders some Enhanced Metafile Format (EMF) files. This issue occurs if you build the EMF files using third-party applications with ExtCreatePen() and ExtCreateFontIndirect().
  • We provided administrators the option to reset the zoom to the default for HTML dialogs in Microsoft Edge Internet Explorer mode.
  • We fixed an issue with Enterprise Mode Site List redirection from Internet Explorer 11 to Microsoft Edge. In certain circumstances, the redirection opens a site in multiple tabs in Microsoft Edge.
  • We fixed an issue that causes Internet Explorer to stop working when you input certain characters in the Input Method Editor (IME).
  • We fixed an issue with PropertyGet in JScript9.dll.
  • We fixed a memory leak that occurs when you use nested classes within VBScript.
  • We fixed an issue that fails to keep the NumLock state after a Fast Startup restart.
  • We fixed an issue with moving certain app windows. Moving these app windows might be unusually slow if a File Explorer window is visible on the screen.
  • We fixed an issue that intermittently prevents the Mail app from accepting keyboard input in the address and subject boxes.
  • We fixed an issue with the UI for renaming files using folder view in File Explorer. The UI fails to properly handle inline composition using the new Japanese IME.
  • We fixed an issue in which the use of App-V intermittently causes black screens to appear when signing in on the credentials page.
  • We fixed an issue with an internet print server that fails to properly package modified printer properties before sending the package to the client.
  • We implemented a Group Policy setting for the following registry value (For more information, see KB5005010):
Registry location: HKLM\Software\Policies\Microsoft\Windows NT\Printers\PointAndPrint

Value name: RestrictDriverInstallationToAdministrators

Value data: 1
  • We fixed an issue that might cause Xbox Game Bar recording features to be unavailable.
  • We fixed an issue that might cause distortion in the audio captured by voice assistants.
  • We fixed an issue that causes a memory leak in lsass.exe when the pTokenPrivileges buffer is not released.
  • We fixed an issue that might cause Kerberos.dll to stop working within the Local Security Authority Subsystem Service (LSASS). This occurs when LSASS processes simultaneous Service for User (S4U) user-to-user (U2U) requests for the same client user.
  • We fixed an issue with a non-paged pool (NPP) leak from the UxSF pool tag. This leak occurs when lsass.exe stops processing asynchronous Security Support Provider Interface (SSPI) calls.
  • We fixed an issue that prevents you from enabling BitLocker on a thinly provisioned virtual machine (VM). The error is “A device attached to the system is not functioning” and the system logs, “STATUS_UNSUCCESSFUL”.
  • We improved the performance of MsSense.exe in environments with User Datagram Protocol (UDP) applications that require high amounts of bandwidth.
  • We fixed an issue in Windows Defender Exploit Protection that prevents some Microsoft Office applications from working on machines that have certain processors.
  • We enabled credentials for Azure Active Directory (Azure AD) Active Directory Federation Services (ADFS) users in Quick Assist.
  • We fixed an issue that sometimes prevents Quick Assist users from using full screen view after they start a remote assistance session.
  • We fixed an issue in which Set-RDSessionCollectionConfiguration does not set the camerastoredirect:s:value custom property.
  • We fixed an IME mode instability in the RemoteApp scenario. You must install this update on the Remote Desktop server and Remote Desktop client.
  • We fixed an issue that causes the IME toolbar to appear even when the RemoteApp is closed.
  • We fixed a paged pool memory leak of the registry keys for the Virtual Desktop ID that occurs in explorer.exe.
  • We made small adjustments to the contrast theme colors, such as making hyperlinks more distinct when you hover over them while you are using the desert theme.
  • We fixed an issue that prevents Narrator and other screen readers from announcing when the Start menu is open in certain cases.
  • We fixed an issue that occurs if the search index is damaged in certain ways; attempts to search using the taskbar or File Explorer fail.
  • We fixed an issue that prevents the search window from appearing on a secondary monitor.
  • We fixed an issue that might cause the File Explorer window to lose focus when you map a network drive.
  • We fixed an issue that sometimes causes the lock screen to appear black if you set up slideshow.
  • We fixed a reliability issue with LogonUI.exe, which affects the rendering of the network status text on the credentials screen.
  • We fixed an issue that prevents you from opening multiple instances of an app using Shift and clicking on the app’s icon in the taskbar.
  • We updated the visual design and animations of the Chat icon on the taskbar.
  • We removed the warning about losing other people’s unsaved work when shutting down or restarting if no other users are signed in.
  • We fixed an issue that might occur when you configure the policy, “Delete user profiles older than a specified number of days on system restart”. If a user has been signed in for longer than the time specified in the policy, the device might unexpectedly delete profiles at startup.
  • We fixed an issue that fails to establish a connection to the Remote Desktop Protocol (RDP) service or immediately drops an RDP connection under certain circumstances.
  • We fixed an issue that might cause input delays for certain Bluetooth mice and keyboards.
  • We fixed an issue that prevents the Start menu from opening after a video driver upgrade.
  • We improved the precision of the estimates for downtime when the estimates are at least two minutes or more.
  • We fixed a Local Security Authority Subsystem Service (LSASS) domain controller memory leak that is reported in Privileged Access Management (PAM) deployments.
  • We fixed an issue that occurs when the Lightweight Directory Access Protocol (LDAP) bind cache is full, and the LDAP client library receives a referral.

Don't forget the AMD Chipset Driver.
Thanks for this because I thought installing only the update is enough but as AMD explained there's another issue that's not fixed by the Windows Update so the chipset driver needs to be separately installed as well.
Surprised to see that it's not available on Gigabyte's website yet.
Edit: Also found the option to install AMD Ryzen Balanced Power Plan included in the chipset driver installer. I wasn't aware of this AMD feature. Nice (y)

Microsoft: Windows KB5006674, KB5006670 updates break printing​

Microsoft says Windows customers are experiencing issues with network printing after installing the Windows 11 KB5006674 and Windows 10 KB5006670 updates issued with this month's Patch Tuesday, on October 12.

Users attempting to connect to printers shared on Windows print servers might encounter multiple errors preventing them from printing over the network.

The errors Windows print clients will encounter after deploying KB5006674 include:
  • 0x000006e4 (RPC_S_CANNOT_SUPPORT)
  • 0x0000007c (ERROR_INVALID_LEVEL)
  • 0x00000709 (ERROR_INVALID_PRINTER_NAME)
The complete list of Windows platforms impacted by this issue includes:
  • Client: Windows 11, version 21H2; Windows 10, version 21H1; Windows 10, version 20H2; Windows 10, version 2004; Windows 10, version 1909; Windows 10, version 1809; Windows 10 Enterprise LTSC 2019; Windows 10, version 1607; Windows 8.1; Windows 7 SP1
  • Server: Windows Server 2022; Windows Server, version 20H2; Windows Server, version 2004; Windows Server, version 1909; Windows Server, version 1809; Windows Server 2008 SP2
As Redmond explains, this known issue affecting printing on both client and server Windows platforms is specific to printer servers which are more commonly found in enterprise environments.

Microsoft said it's working on finding a solution to allow print clients to establish RPC packet privacy connections to Windows print servers using RPC over SMB.

Microsoft provides a workaround​

Customers impacted by these printing problems can now use an official workaround provided by Microsoft to fix the issue.

The steps should ONLY be taken on affected print servers that meet the following prerequisite: "print clients must have installed a Windows update released on or after January 2021 before the print server has installed" the October 2021 updates.

If the workaround requirements are met, Microsoft asks customers to "ensure that network security and VPN solutions allow print clients to establish RPC over TCP connections to print server over the following port range:"
  • Default start port: 49152
  • Default end port: 65535
  • Port Range: 16384 ports
Redmond also provides the following articles for additional guidance:
