Update KB5017381 for Windows Server 2022

Cumulative preview update KB5017381 for Windows Server 2022 raises the OS build to 20348.1070. According to Microsoft, the preview update contains the following fixes and two new features:

  • New! Introduces WebAuthn redirection. It lets you authenticate in apps and on websites without a password when you use Remote Desktop. Then, you can use Windows Hello or security devices, such as Fast Identity Online 2.0 (FIDO2) keys.
  • New! Improves storage replication that occurs over low bandwidth or congested wide area networks (WAN).
  • Addresses an issue that requires you to reinstall an app if the Microsoft Store has not signed that app. This issue occurs after you upgrade to Windows 10 or a newer OS.
  • Addresses an issue that stops codecs from being updated from the Microsoft Store.
  • Addresses an issue that affects cached credentials for security keys and FIDO2 authentications. On hybrid domain-joined devices, the system removes these cached credentials.
  • Addresses an issue that affects a network's static IP. The issue causes the configuration of the static IP to be inconsistent. Because of this, NetworkAdapterConfiguration() fails sporadically.
  • Addresses an issue that affects rendering in Desktop Window Manager (DWM). This issue might cause your device to stop responding in a virtual machine setting when you use certain video graphics drivers.
  • Addresses a rare stop error that happens after you change the display mode and more than one display is in use.
  • Addresses an issue that affects graphics drivers that use d3d9on12.dll.
  • Addresses an issue that affects URLs generated by JavaScript: URLs. These URLs do not work as expected when you add them to the Favorites menu in IE mode.
  • Addresses an issue that affects window.open in IE mode.
  • Addresses an issue that successfully opens a browser window in IE mode to display a PDF file. Later, browsing to another IE mode site within the same window fails.
  • Addresses an issue that forces the IE mode tabs in a session to reload.
  • Introduces a Group Policy that enables and disables Microsoft HTML Application (MSHTA) files.
  • Addresses an issue that occurs when the input queue overflows. This might cause an application to stop responding.
  • Addresses an issue that affects the Microsoft Japanese input method editor (IME). Text reconversion fails when you use some third-party virtual desktops.
  • Addresses an issue that affects the App-V client service. The service leaks memory when you delete App-V registry nodes.
  • Addresses an issue that might change the default printer if the printer is a network printer.
  • Addresses an issue that affects Windows Defender Application Control (WDAC) path rules. This issue stops .msi and PowerShell scripts from running.
  • Addresses an issue that causes WDAC to log 3091 and 3092 events in audit mode.
  • Addresses an issue that affects Group Policy Objects. Because of this, the system might stop working.
  • Addresses an issue that affects Windows Defender Application Control (WDAC). It stops WDAC from logging .NET Dynamic Code trust verification failures.
  • Addresses an issue that occurs when a WDAC policy fails to load. The system logs that failure as an error, but the system should log the failure as a warning.
  • Addresses an issue that affects non-Windows devices. It stops these devices from authenticating. This issue occurs when they connect to a Windows-based remote desktop and use a smart card to authenticate.
  • Addresses an issue that might bypass MSHTML and ActiveX rules for WDAC.
  • Addresses an issue that affects WDAC policies. These policies will not apply on a system when you enable SecureLaunch.
  • Addresses an issue that affects the Settings app on server domain controllers (DCs). When you access System > Display, the Settings app stops working.
  • Addresses an issue that affects the Local Security Authority Subsystem Service (LSASS). LSASS might stop working on a child domain controller (DC). This might occur when you lose the connection to a root DC while you are searching for a name that is in many forests or a security ID (SID).
  • Addresses an issue that affects the FindNextFileNameW() function. It might leak memory.
  • Addresses an issue that affects robocopy. Robocopy fails to set a file to the right modified time when using the /IS option.
  • Addresses an issue that affects cldflt.sys. A stop error occurs when it is used with Microsoft OneDrive.
  • Addresses an issue that affects the Get-SmbServerNetworkInterface cmdlet. It only retrieves a subset of the available network interfaces.
  • Addresses an issue that affects the Get-SmbServerConfiguration cmdlet. It only allows you to run it if you are an administrator.
  • Addresses an issue that affects the LanmanWorkstation service. When you mount a network drive, the service leaks memory.
