Microsoftは本日、Windows 10の最新プレビュービルド「Windows 10 Insider Preview Build 18242 (19H1)」をリリースしました(Windows Blog)。
公開されたプレビュー版は来年春に公開される予定のWindows 10の大型アップデート「19H1」の開発版ビルドです。Windows Insiders Programの更新オプションで「Skip Ahead」を選択しているユーザーはWindows Updateを利用して最新版に更新することができます。
Build 18242には新機能は追加されておらず、以下の不具合が修正されています。
- We fixed an issue resulting in the background of notifications and the Action Center losing color and becoming transparent in the last two flights.
- We fixed an issue where thumbnails and icons might not be rendered if there were any video files saved to the desktop.
- We fixed an issue resulting in the back button in Settings and other apps becoming white text on a white background if you hovered over it.
- We fixed an issue resulting in certain apps crashing when you tried to save a file from the app.
- We fixed an issue resulting in nearby sharing not working for local accounts where the account name contained certain Chinese, Japanese, or Korean characters.
- We fixed an issue resulting in rendering issues in certain types of PDFs in Microsoft Edge.
- The Emoji Panel is now draggable if you would like to move it to a different position.
- We fixed an issue resulting in Narrator not reading selected word choices when typing using an IME (for example, in Japanese).
- Some Insiders who have opted in to Skip Ahead may notice differences when using the Japanese IME in today’s build. We’re trying something out and will have more details about it later. If you have any feedback about your experience when using the IME, please let us know via Feedback Hub.
- We fixed an issue where certain Bluetooth audio devices wouldn’t play sound in apps that also used the microphone.
- We fixed an issue resulting in slower resume from hibernation on certain devices in the last few flights.
- We fixed an issue resulting in Windows Hello spending more time in the “Getting Ready” state in recent builds.
- We fixed an issue resulting in an unexpectedly increased use of battery recently when using certain apps like OneNote.
- We fixed an issue in PowerShell where it wasn’t displaying characters correctly in Japanese.
なおこのビルドにはタスクマネージャーでCPU使用率が正確に表示されない問題と、「バックグラウンドプロセス」を展開する矢印が点滅する既知の不具合が存在しています。
また開発者向けに、FastリングからSlowリングに切り替えると、開発者モードを有効にするというようなオプションコンテンツが失敗するという問題が掲載されています。これらオプションコンテンツを使用する場合Fastリングのままにしておかないといけないとのことです。
