Microsoftは2日(現地時間)、Windows 10の最新プレビュービルド「Windows 10 Insider Preview build 17112」をリリースしました(Windows BlogMSPoweruser)。

公開されたプレビュー版は、Windows 10の次の大型アップデート「Redstone 4」の開発版ビルドです。Windows Insiders Programに参加しているFastリングユーザーはWindows Update経由で最新版に更新することができます。

Build 17112は基本的には不具合の修正がメインのアップデートですが、いくつかの既知の問題が存在します。Windows Mixed Realityに関しては、低フレームレートで動作したり、起動時にクラッシュする問題が発生する可能性があり、そのほかMicrosoft Storeが完全に壊れたり消えてしまう不具合も存在します(解消法はこちら)。
