不过遗憾的是，在Build 18247上并没有出现新功能特性，而是和上次一样，着眼于BUG修复和稳定性改善。这番反常的举动可能并非Insider团队的工程师们懒惰，或许合理的解释是，与微软将在十月更新结束后对Windows 10团队进行重整有关，一些计划不得不搁置或暂时等待。

修复的BUG主要有五项，包括某些图标在任务栏中不可见、Edge首次启动后无法调用输入法、Web视图下键盘无响应、“Your Phone”新增“Preview预览”LOGO等。

更新列表:

General changes, improvements, and fixes for PC

• We fixed an issue resulting in Narrator text to speech not making sense when reading Narrator’s Quick Start pop up in Japanese.
• We fixed an issue resulting in app icons sometimes becoming invisible in the taskbar in recent flights.
• We fixed an issue that could result in an IME not working in Microsoft Edge the first time it was launched.
• We fixed an issue resulting in WebView controls potentially not responding to keyboard.
• Rolling out this week, along with more bug fixes, we have added a “Preview” tag to Your Phone app as we continue to finetune the based on your feedback. Keep it coming via Feedback Hub.

Known issues

• When using dark mode, File Explorer’s context menu has an unexpectedly thick white border.
• Task Manager is not reporting accurate CPU usage. This should be fixed in the next flight.
• Arrows to expand “Background processes” in Task Manager are blinking constantly and weirdly.

Known issues for Developers

• If you install any of the recent builds from the Fast ring and switch to the Slow ring – optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.
