Preview-Update KB5040527 für Windows 11 22H2-23H2

Für Windows 11 Version 22H2-23H2 ist das Preview Update KB5040527 freigegeben worden und stellt Neuerungen sowie Fixes für diese Windows-Version bereit. Microsoft spricht von einem Gradual Rollout mit Neuerungen, die dieses Update mitbringt.

• [Notification for Windows Share in China] New! For nearby sharing to work, Wi-Fi and Bluetooth must be on. If they are off when you turn on nearby sharing, Windows will ask you to allow them to be turned on.
• [Start menu] New! You can drag apps from the Pinned section of the menu and pin them to the taskbar.
• [Taskbar]
  • New! When the taskbar has keyboard focus (WIN + T), you can press a letter, and you will go to the app whose name starts with that letter. When you press a letter more than once, you will go to the next app whose name starts with that letter. Pressing a letter more than once only works if there are multiple pinned or open apps whose name starts with that letter. If you are using an uncombined taskbar, when you press a letter, you go to the window whose name starts with that letter. Also, when you press Home and End, the keyboard focus changes to the first and last items in the taskbar.
  • The End task option no longer shows a not responding dialog before it stops a task. This option is only available when you turn on End task in Settings > System > For Developers.
• [File Explorer]
  • New! When you right-click a tab, you have the choice to duplicate it.
  • A memory leak occurs when you interact with archive folders.
  • File Explorer stops responding when you browse within it.
  • When you search from Home for the first time, you might not get any results.
  • The address bar dropdown menu might appear when you do not expect it.
  • When you use the Save dialog to save a file to Gallery, an error occurs. Because of this update, your file saves to the Pictures library instead.
  • The search box does not show the correct folder name when you are in Gallery.
  • A blank area shows at the top of File Explorer.
  • The back and forward mouse buttons do not work when you hover over the Recommended Files section of Home.
  • Images flash when you view them in the Gallery.
• [Desktop icons] Spacing between them might become very wide.​​​​​​​​​​​​​​

Im Support-Beitrag für das Update werden weitere Qualitätsverbesserungen und Fixes aufgelistet für ein normales Rollout aufgelistet.

• [Bluetooth] You cannot put calls on hold from Bluetooth peripherals.
• [FrameShutdownDelay] The browser ignores its value in the "HKLM\SOFTWARE\Microsoft\Internet Explorer\Main" registry key.
• [Windows Server vNext] In the latest build, the cache size display behavior is not what you expect.
• [Group Policy Preferences Item Level Targeting (ILT) and Local Users and Groups] You cannot choose a group from the target domain for ILT. Also, you cannot choose an account from Local Users and Groups. The forest does not appear. This issue occurs when you deploy multiple forests, and the target domain has a one-way trust with the domain of the admin. This issue affects Enhanced Security Admin Environment (ESAE), Hardened Forests (HF) or Privileged Access Management (PAM) deployments.
• [Transmission Control Protocol/Internet Protocol (TCPIP)] The issue causes high CPU usage and loss of packets. It also affects TCP connection success rates.
• [NetAdapterCx module] A system stops responding when large amounts of data travel over Wi-Fi. This issue occurs on devices that have certain wireless network cards.
• [Universal Print clients] They fail to communicate with the Universal Print service. This affects printing functions. This issue occurs when you turn on Web Proxy Auto Discovery (WPAD).
• [Print Support App] When you use the app with a USB device, the app stops responding and does not print. This issue also limits the functions of the user interface.
• [Autopilot] Using it to provision Surface Laptop SE devices fails.
• [Windows Defender Application Control (WDAC)]
  • A memory leak occurs that might exhaust system memory as time goes by. This issue occurs when you provision a device.
  • When you apply WDAC Application ID policies, some apps might fail.
• [Windows Kernel Vulnerable Driver Blocklist file (DriverSiPolicy.p7b)] This update adds to the list of drivers that are at risk for Bring Your Own Vulnerable Driver (BYOVD) attacks.
• [Windows Backup] Backup sometimes fails. This occurs when a device has an Extensible Firmware Interface (EFI) system partition (ESP).
• [Cache manager] It might stop responding. This occurs when you use Hyperthreading on Windows Server 2022.
• [Windows Update Agent API (WUA) (known issue)] You might get an empty result when you query the properties of IUpdate objects in the IUpdateCollection for Windows updates. You might also get the error code 0x8002802B (TYPE_E_ELEMENTNOTFOUND). This occurs when you call methods on the object from a script (PowerShell, VBScript, and so on).
• [Windows Enterprise subscription (known issue)] When you upgrade from Windows Professional, the upgrade might fail. In Task Scheduler, a message shows in the LicenseAcquisition scheduled task. The message is, "Access denied error (error code 0x80070005)."

Diese lange Liste an Neuerungen und Fixes wird im Sicherheitsupdate für den Folgemonat integriert. Das Preview-Update ist optional und wird angeboten, wenn der Nutzer explizit in der Einstellungen-Seite optionale Updates zur Installation auswählt. Sofern die Option aktiviert ist, dass optionale Updates installiert werden, kann Windows 11 das Update auch automatisch installieren. Das Update wird über Windows Update angeboten, lässt sich aber auch aus dem Microsoft Update Catalog herunterladen und installieren. Das neueste Servicing Stack Update (SSU) ist integriert, um diverse Probleme zu beheben. Weitere Details, z.B. zu den Installationsvoraussetzungen, sind im Zweifelsfall dem Support-Beitrag zu entnehmen. Dort sind auch, sofern bekannt, Probleme aufgelistet.
