KB4507466 (OS Build 17134.915)

Version 1803用の累積アップデートKB4507466では、サインアウトして再度サインインするまでデバイスがMicrosoftアカウントを認識できないという問題の修正や、ファイルやフォルダ、デバイス設定を管理するアプリケーションに影響する問題の修正、Window-Eyesスクリーンリーダーアプリケーションとの互換性の改善、デバイスをリセットするときにアプリのアクセス許可設定を維持できなかった問題の修正などが行われています。

ハイライト:

  • Updates an issue that prevents a device from recognizing a Microsoft account until you sign out and sign in again. 
  • Updates an issue that affects applications that manage files, folders, and device settings.
  • Improves compatibility with the Window-Eyes screen reader application.
  • Updates an issue to keep your App permissions settings when resetting your device.

改良と修正:

  • Addresses a performance issue that may occur on some websites that use WebAssembly. 
  • Addresses an issue that may prevent the personal identification number (PIN) prompt from appearing when authenticating in Internet Explorer. 
  • Updates time zone information for Brazil. 
  • Addresses an issue that fails to bypass automatic sign in (Autologon) when you press and hold the Shift key during startup. 
  • Addresses an issue that prevents the Windows Event Log service from processing notifications that the log is full. This causes issues with some Event Log behaviors such as archiving the log when it reaches a maximum file size and you’ve configured the "Archive the log when full, do not overwrite events" setting. Additionally, the Local Security Authority (LSA) cannot handle CrashOnAuditFail scenarios when the Security Log is full, and events cannot be written. 
  • Addresses an issue that prevents a system from recognizing a Microsoft account or Azure Active Directory account until the user signs out and signs in again. 
  • Addresses an issue that may prevent the Netlogon service from establishing a secure channel and reports the error, “0xC000007A – ERROR_PROC_NOT_FOUND.” 
  • Addresses an issue that fails to update the PIN policy (minimum length, required digits and special characters, etc.) for Windows Hello for Business when a PIN already exists on the machine. 
  • Addresses an issue that may sometimes cause systems that have Trusted Platform Module (TPM) devices to stop working. 
  • Addresses an issue that may cause authentication to fail when using Windows Hello for Business on a server running Windows Server 2016 with the Server Core option installed. 
  • Addresses an issue that causes a device to stop working because of a race condition between stream tear down and sync root disconnect.
  • Addresses an issue that causes applications that use windows.storage.dll to stop working and displays ExceptionCode c0000005 (Access violation) when the process closes. 
  • Reinforces the Certificate Revocation List (CRL) on Internet Key Exchange version 2 (IKEv2) machines for certificate-based virtual private network (VPN) connections, such as Device Tunnel, in an Always On VPN deployment. 
  • Improves performance for Server Message Block (SMB) clients that have directories that contain more than 500,000 files.
  • Addresses an issue that prevents Microsoft Application Virtualization (App-V) scripting from working if you run it when you’re not connected to a domain controller (DC). App-V scripting also fails when you run it in an environment that only contains Microsoft Azure Active Directory.
  • Addresses an issue with opening or using the Window-Eyes screen reader application that may result in an error and prevent some features from functioning as expected.
  • Addresses an issue that may fail to keep App permissions settings when you select Keep my files after selecting Reset this PC.
  • Addresses an issue that may cause a cluster node to lose membership in a cluster and cause all its workloads to fail over. This issue may occur when a cluster node creates a Live Dump.

更新プログラムには以下の既知の不具合が3件存在します。

  • 特定の操作をクラスター共有ボリューム上のファイルやフォルダーに対して実行すると「STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)」が発生する
  • 更新インストール後の最初のログオン画面でブラックスクリーンが表示される場合がある
  • WDSまたはSCCMからPEXイメージを使用して起動するデバイスが"Status: 0xc0000001, Info: A required device isn't connected or can't be accessed"というエラーで起動に失敗する

アップデートはWindows Update経由で自動的にインストールされますが、Microsoft Update Catalogからファイルダウンロードすることもできます。
