Microsoftein Januar-Februar 2024von Patch Tuesday Damals veröffentlichte Patch-Operationen WinRE Es waren viele Änderungen auf der Partitionsseite erforderlich.

Zuerst CVE-2024-20666 Schwachstelle zur Umgehung der BitLocker-Sicherheitsfunktionlity Als das Update für die Systemadministratoren veröffentlicht wurde, begannen sie darüber zu reden.

Detaillierte Beschreibung des Windows-Updates KB5034441

Windows Ein Angreifer mit physischem Zugang zu den Plattformen BitLocker Es wurde eine schwerwiegende Sicherheitslücke entdeckt, die den Zugriff auf verschlüsselte Daten ermöglicht. Diese Schwachstelle CVE-2024-20666 Es ist definiert als Windows 10-, Windows 11- und Windows Server 2022-Systeme und betrifft diese möglicherweise.

Microsofthat zum 9. Januar 2024 ein Update veröffentlicht, um diese Schwachstelle zu beheben. Bei diesem Update treten jedoch einige technische Probleme auf. Das Update erfolgt automatisch, unabhängig davon, ob BitLocker auf einem System aktiviert ist. Windows Update Es wird verteilt durch.

Damit das Update erfolgreich installiert werden kann, müssen in der Wiederherstellungspartition der Systeme mindestens 250 MB freier Speicherplatz vorhanden sein.

Wenn WinRE Wenn während des Updates nicht genügend freier Speicherplatz auf der Partition vorhanden ist 0x80070643 – ERROR_INSTALL_FAILURE Aufgrund von Fehlern kann es zum Scheitern kommen. Damit das Update erfolgreich abgeschlossen werden kann, müssen Benutzer in diesem Fall den erforderlichen Speicherplatz in der WinRE-Partition bereitstellen oder die von den Systemadministratoren festgelegten Vorkehrungen treffen.

Manueller Winre-Extend-Prozess für Update 0x80070643 Fehler

Für den Fehler 5034441x0 während des Windows Update KB80070643-Prozesses muss WinRE Partition Extend auf dem Server durchgeführt werden.

Um das Problem der Umgehung der BitLocker-Sicherheitsfunktion in Windows zu lösen, muss die Größe der erforderlichen 250 MB großen WinRE-Partition geändert werden.

  • YÖffnen Sie die Eingabeaufforderung als Administrator:
    • Öffnen Sie als Administrator ein CMD-Fenster.
  • Überprüfen Sie den WinRE-Status:
    • reagentc /info indem Sie den Befehl ausführen WinREÜberprüfen Sie, ob es installiert ist. Falls installiert, WinRESie sehen den Verzeichnispfad von .
  • WinRE deaktivieren:
    • reagentc /disable Deaktivieren Sie WinRE vorübergehend mit dem Befehl.
  • Verkleinern der Betriebssystempartition:
    • Zur Datenträgerverwaltung diskpart Führen Sie den Befehl aus.
    • list disk Verwenden Sie diese Option, um die Festplatten aufzulisten und die Festplatte auszuwählen, auf der sich Ihr Betriebssystem befindet. select disk <disk numarası> Mit auswählen.
    • list partition Verwenden Sie diese Option, um die Partitionen aufzulisten und die Betriebssystempartition auszuwählen. select partition <partition numarası> Mit auswählen.
    • Betriebssystem shrink desired=250 minimum=250 Verkleinern Sie es mit dem Befehl um 250 MB.
  • WinRE-Partition löschen:
    • WinRE-Partition select partition <WinRE bölüm numarası> ve delete partition override Mit Befehlen löschen.
  • Erstellen einer neuen Wiederherstellungspartition:
    • Die Festplatte ist GPT oder MBR list disk Überprüfen Sie es mit dem Befehl. Wenn es GPT ist, create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac Befehl, MBR create partition primary id=27 Verwenden Sie den Befehl.
    • neue Folge format quick fs=ntfs label="Windows RE tools" Schnellformatierung mit .
  • WinRE erneut aktivieren:
    • reagentc /enable Aktivieren Sie WinRE mit dem Befehl und erneut reagentc /info Überprüfen Sie mit , ob die Installation erfolgreich war.
  • Diskpart beenden:
    • exit Beenden Sie die Diskpart-Anwendung mit dem Befehl.

WinRE-Prozess mit PowerShell erweitern

WinRE-Partition erweitern für den Prozess verwendet werden müssen Skript Ich teile den Link und den Code-Blog unten.

  • PowerShell muss als Administrator ausgeführt werden
  • Wir müssen das von Ihnen heruntergeladene PowerShell-Skript ausführen.
  • Bevor Sie mit dem Erweiterungsprozess beginnen WinRE und fordert Sie auf, den Namen des Laufwerks und des Ordners einzugeben, der gesichert werden soll.
  • Anschließend erfolgen alle Schritte automatisch. Wenn das Skript nicht mehr ausgeführt wird, wird die WinRE-Partition auf 250 MB erweitert.
