KB4469342 (OS Build 17763.168)の変更点

Windows 10 Version 1809用の累積アップデートKB4469342では、特定アプリとファイルタイプの組み合わせに対し、Win32プログラムの規定値が設定できない問題の修正や、Microsoft Compatibility Listを使用しないときにInternet Explorerのパフォーマンスが低下する問題の修正、Microsoft EdgeでのライブTV Huluのコンテンツの再生がうまくいいかない問題の修正などが行われています。

  • Addresses an issue in Microsoft Edge with using the drag-and-drop feature to upload folders from the Windows desktop to a file hosting service website, such as Microsoft OneDrive. In some scenarios, files contained in the folders fail to upload, with possibly no error reported on the web page to the user. 
  • Addresses an issue that degrades Internet Explorer performance when you use roaming profiles or you don't use the Microsoft Compatibility List. 
  • Addresses updated time zone information for Fiji. 
  • Addresses time zone changes for Moroccan daylight standard time.
  • Addresses time zone changes for Russian daylight standard time.
  • Addresses an issue that causes display settings to stop working when changing a multi-monitor configuration. 
  • Addresses an issue that displays a black screen on some servers when waking a display from sleep. 
  • Addresses an issue with long delays in taking a photo when using the Camera app in certain lighting conditions. 
  • Addresses an issue that prevents live TV Hulu content from playing in Microsoft Edge; instead, a black screen appears. 
  • Addresses an issue that stops Bluetooth® headsets from receiving audio input after several minutes of listening. 
  • Addresses an issue that causes the Brightness slider preference to be reset to 50% when the device restarts. 
  • Addresses an issue with the OEM manufacturing processes when running sysprep /generalize
  • Addresses an issue with Microsoft Intune that causes devices to be incorrectly marked as not compliant because a firewall incorrectly returns a 'Poor' status. As a result, the affected devices will not receive conditional access compliance approval and may be blocked from access to corporate resources such as email. 
  • Addresses a performance issue with vSwitch on network interface cards (NIC) that do not support Large Send Offload (LSO) and Checksum Offload (CSO). 
  • Updates the Wi-Fi policy for service set identifier (SSID) filtering to avoid filtering out Wi-Fi Direct devices. 
  • Addresses an issue that causes rasman.exe to stop responding. 
  • Addresses an issue in which regedit.exe fails to add double null terminator to REG_MULTI_SZ values in the Windows registry. The missing terminator may prevent services and applications from reading REG_MULTI_SZ values that regedit.exe adds after installing the operating system. 
  • Addresses an issue with RemoteApp visibility that may cause the main window to disappear until the user clicks the screen.
  • Addresses an issue that prevents some users from setting Win32 program defaults for certain app and file type combinations using the Open with… command or Settings > Apps > Default apps.
  • Addresses an issue that may cause mapped drives to fail to reconnect after starting and logging onto a Windows device.

なおこの更新プログラムには、特定のファイルを再生するとWindows Media Playerのシークバーが使用できなくなる問題と、nVidia製のGPUを搭載しているPCで動画の再生中にMicrosoft Edgeがクラッシュする問題という二つの既知の不具合が存在します。
