Windows 10 Preview Updates (20. Oktober 2020)

[English]Am 20. Oktober 2020 hat Microsoft verschiedene kumulative Updates als optional installierbare Previews für Windows 10 Version 1809 bis 1909 freigegeben. In Windows 10 Version 190x wird durch das Preview Update der Skype Lite-Verschnitt Meet Now in der Taskleiste verankert. Zudem korrigieren die Preview-Updates einige nervige Probleme wie verschwindende USB-Drucker oder das durch das letzte Oktober-Update verursachte Flackern des Bildschirms. Hier einige Details zu den jeweiligen Updates.

Eine Liste der Updates lässt sich auf dieser Microsoft-Webseite abrufen. Ich habe nachfolgend die Details herausgezogen. Die Update-Installation setzt ein vorhandenes aktuelles Servicing Stack Update (SSUs) voraus. Microsoft veröffentlicht inzwischen eine Übersicht aktueller Servicing Stack Updates (SSUs) unter ADV990001 (falls die nicht aktuell ist, im Microsoft Update Catalog nach Servicing Stack Updates suchen lassen).

Wichtig: Ab Juli 2020 deaktivieren alle Windows Updates die RemoteFX vGPU-Funktion aufgrund der Sicherheitslücke CVE-2020-1036 (siehe auch KB4570006). Nach der Installation dieses Updates schlagen Versuche, virtuelle Maschinen (VM) zu starten, bei denen RemoteFX vGPU aktiviert ist, fehl.

Update KB4580386 für Windows 10 Version 190x

Das Preview-Update KB4580386 ist kumulativ und steht für die Windows 10 Versionen 1903 und 1909 sowie für Windows Server Version 1903 und Windows Server Version 1909 bereit zur Verfügung. Es hebt die OS-Build auf 18362.1171  (Windows 10 V1903) bzw. auf 18363.1171 (Windows 10 V1909). Es beinhaltet Qualitätsverbesserungen aber keine neuen Betriebssystemfunktionen. Hier die Liste der Verbesserungen, von Microsoft als Highlights bezeichnet:

• Introducing Meet Now (Skype-Lite) in the Windows 10 Taskbar. Meet Now makes it easy to connect with anyone in as little as two clicks for free and each call can last up to 24 hours.
• Updates an issue that might prevent a Microsoft Xbox Game Pass user from playing certain games that are eligible for play.
• Updates a reliability issue that causes the screen to flash constantly.
• Updates an issue that causes a USB printer port to disappear after restarting when the printer device is turned power off.

Probleme mit verschwindenden Druckern, die seit Monaten auftraten sowie das Flackern des Bildschirms als Folge des Oktober-Updates (siehe Patchday-Nachlese: Windows 10 V2004 Update KB4579311 macht Probleme) sollen behoben sein. Hinzukommen folgende Fixes und Verbesserungen an der Windows 10 Version 1909, die aber identisch mit der Version 1903 (Update steht auch für die Hololens bereit) sind:

• Addresses an issue with using Group Policy Preferences to configure the homepage in Internet Explorer.
• Allows administrators to use a Group Policy to enable Save Target As for users in Microsoft Edge IE Mode.
• Addresses an issue with untrusted URL navigations from Internet Explorer 11 by opening them in Microsoft Defender Application Guard using Microsoft Edge.

• Addresses an issue that causes an application to stop responding temporarily, which causes extra z-order operations that affect the Window.Topmost property of a window.
• Addresses an issue that might cause DDE apps to stop working.
• Addresses an issue that occurs when you first sign in to an account or unlock an existing user session using Remote Desktop Services (RDS). If you enter an incorrect password, the current keyboard layout changes unexpectedly to the system default keyboard layout. This keyboard layout change might cause additional attempts to sign in to fail or lead to account lockouts in domains with low account lockout thresholds.
• Addresses an issue with the CleanupProfiles Group Policy object (GPO). After you upgrade the operating system, when you configure the CleanupProfiles GPO, it fails to remove unused user profiles.
• Addresses an issue that displays the incorrect CPU frequency for certain processors.

• Addresses an issue with SQL Server that might cause performance issues if you configure a Linked Server provider to load out-of-process.
• Addresses an issue that might degrade Windows performance and prevent the LanmanServer service from starting when third-party software uses LanmanServer custom file system controls (FSCTL).
• Addresses an issue with deduplication that causes long wait times on Resilient File System (ReFS) Cluster Shared Volumes (CSV).
• Addresses an issue that might prevent some applications from behaving correctly. This occurs when you publish them as Remote Application Integrated Locally (RAIL) applications using RDS and change the docking for an AppBar window.
• Addresses an issue with a deadlock in the Transmission Control Protocol/Internet Protocol (TCPIP) driver that causes the operating system to stop working or stop responding.
• Addresses an issue that causes the Routing and Remote Access Service (RRAS) to stop responding for new connections. However, RRAS continues working for existing connections.

  • Verifying that source machines have installed the current update.For more information, see Storage Migration Service October 2020 Update.

Dieses Update wird über Windows Update angeboten und installiert, ist aber auch im Microsoft Update Catalog (nicht jedoch für WSUS) erhältlich. Laut Microsoft ist das Update optional und wird nur bei einer Update-Suche gefunden. Microsoft empfiehlt dringend, dass Sie das neueste Service Stack Update (SSU) für Ihr Betriebssystem installieren, bevor Sie das neueste kumulative Update (LCU) installieren. Microsoft gibt ein bekanntes Problem an,  das das Update verursacht und welches im KB-Artikel dokumentiert ist (siehe auch KB4577062 blockiert Funktionsupdates auf Windows 10 V190x und 2004).

Zudem hat Microsoft ein Update direkt für den Windows Update Client veröffentlicht, um dessen Zuverlässigkeit zu verbessern. Das wird außerhalb von Windows Update ausgerollt, wenn die Maschine kompatibel und keine LTSC-Variante ist und Updates nicht per GPO blockiert wurden.

Update KB4580390 für Windows 10 Version 1809

Das kumulative Update KB4580390 hebt die OS-Build (laut MS) auf 17763.1554 und beinhaltet Qualitätsverbesserungen aber keine neuen Betriebssystemfunktionen. Als Highlight wird in Problem mit der Out-of-Box-Benutzererfahrung auf einigen Geräten, das den Abschluss eines Upgrades verhindert, benannt. Dieses Problem tritt auf, weil das Gerät keine Benutzereingaben auf der Seite Microsoft Software-Lizenzbedingungen oder der Cortana-Seite zulässt. Hier die Liste der weiteren Verbesserungen:

• Addresses an issue with untrusted URL navigations from Internet Explorer 11 by opening them in Microsoft Defender Application Guard using Microsoft Edge.
• Addresses an issue that displays a black screen to Windows Virtual Desktop (WVD) users when they attempt to sign in.

• Addresses an issue that causes an application to stop responding temporarily, which causes extra z-order operations that affect the Window.Topmost property of a window.
• Addresses an issue with the CleanupProfiles Group Policy object (GPO). After you upgrade the operating system, when you configure the CleanupProfiles GPO, it fails to remove unused user profiles.
• Addresses an issue that fails to set the desktop wallpaper as configured by a GPO when you specify the local background as a solid color.
• Addresses an issue that prevents you from signing in on certain servers. This occurs when you enable a Group Policy that forces the start of a computer session to be interactive.
• Addresses an issue that occurs when you first sign in to an account or unlock an existing user session using Remote Desktop Services (RDS). If you enter an incorrect password, the current keyboard layout changes unexpectedly to the system default keyboard layout.
