Microsoftは31日(現地時間)、Windows 10 Version 1709用の累積アップデート「KB4058258」をリリースしました(MSPoweruser)。


更新プログラムはWindows Updateを利用して導入することが可能で、システムが広色域をサポートするディスプレイに接続されているときに色が歪む互換性の問題や、スリープ解除後にレガシーAMDディスプレイアダプタに接続されている2台目のモニタが点滅する問題、Alt + Shiftを使用してキーボード言語を切り替えると遅延が発生する問題などが修正されています。

  • Addresses a compatibility issue where colors are distorted when the system is connected to displays that support wide color gamut.
  • Addresses a condition where a second monitor that is connected to legacy AMD display adapters flashes after waking from sleep.
  • Addresses issue that causes delays when switching keyboard languages using Alt+Shift.
  • Addresses compatibility issues when rendering certain closed captions or subtitle formats during video playback.
  • Addresses issue where the Microsoft Edge Allow Extension Group Policy for the disabled state was not working.
  • Provides additional protections for 32-bit (x86) versions of Windows 10, version 1709.
  • Resolves the issue reported by some customers on a small subset of older AMD processors where the processor entered an unbootable state after installing January 3, 2018—KB4056892 (OS Build 16299.192).


  • Windows Update History reports that KB4054517 failed to install because of error 0x80070643.
  • Because of an issue that affects some versions of antivirus software, this fix applies only to computers on which the antivirus ISV updated the ALLOW REGKEY.
  • After installing this update, some users may experience issues logging into some websites when using third-party account credentials in Microsoft Edge.

更新後Windows 10のビルド番号は「16299.214」になります。
