Microsoftは22日(現地時間)、Windows 10 Version 1709(Fall Creators Update)用の累積アップデートKB4089848を公開しました(MSPoweruser)。

更新プログラムはシステムの品質を改善するもので、新たな機能は追加されていません。KB4089848では、Windows Ribbonコントロールで発生するGDIハンドルリークの修正や、Bluetoothデバイスが再起動後にデータを受信できない問題、BitLockerでドライブの復号化または暗号化中に、暗号化ファイルシステム(EFS)で保護されたファイルが破損する可能性のある問題などが修正されています。


  • Addresses issue with a GDI handle leak in the Windows Ribbon control.

  • Addresses issue where users can't select OK after entering credentials in command line on Windows Server version 1709.
