Windows 10 Insider Preview Build 18247 released.

General changes, improvements, and fixes

  • 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.
