With today's release of Windows 10 Insider Preview Build 18252, the 19H1 development branch has formally moved over to both the Fast and Skip Ahead rings. This development branch was previously only available in the Skip Ahead rings, but now that the Windows 10 October 2018 Update has been released, 19H1 is now the current and only version being actively developed.

Build 18242 Insider Update

As always, if you are in either the Skip Ahead or Fast ring you can update to this new build by going into Settings -> Update & Security -> Windows Update and then checking for new updates.

Network Improvements

With this release, Windows now has advanced IP settings available that allow you to configure a static IP address and your own DNS server settings. These settings were previously only available in the network adapter properties in the Control Panel.

This build also introduces a new icon that is displayed when there is no Internet connection. This new icon appears as a globe, with a smaller stop symbol overlaid over it as seen below.

New Microphone indicator on task bar

As malware and other unwanted activities continue to try and access a user's microphone, it is important to know when your microphone is active. With this build, a microphone icon will be shown on the system tray when your microphone is in use.

This will allow users to easily see if their microphone is connected when they do not wish it to be.

New Ebrima font addition with ADLaM support

The Windows team is pleased to announce you can now read your ADLaM documents and webpages with the Windows Ebrima font!

Task Manager bugs fixed

With this release, Microsoft finally fixed the issues in Task Manager that cause CPU usage to be incorrectly displayed. This build also fixes a bug in Task Manager where the arrows to expand Background Processes would blink repeatedly.

To see the entire release notes, you can read the blog post or view them below.

General changes, improvements, and fixes for PC

  • We fixed the issue causing Task Manager to report inaccurate CPU usage.
  • We fixed the issue where the arrows to expand “Background processes” in Task Manager blink constantly and weirdly.
  • We added a microphone icon in the system tray which appears when your microphone is in use.
  • Pressing F4 when in Registry Editor will now place the caret at the end of the address bar, expanding the autocomplete dropdown.
  • We fixed an issue where when using dark mode File Explorer’s context menu had an unexpectedly thick white border in recent builds.
  • We fixed an issue resulting in the advanced startup pages not rendering text correctly (showing square boxes instead) in certain languages, like Thai.
  • We fixed the issue causing Narrator to crash when reading by line in a Command Prompt.
  • We fixed the issue where Narrator did not read out the Windows Security application name in Shell Notification area (Systray) and only read the recommended actions.
  • The corresponding Ethernet adapter name will now be listed in the sidebar under the “Ethernet” header so you can easily differentiate Ethernet entries at a glace if there’s more than one.
  • In RS5 we introduced extra pages to the Emoji Panel when using it in Chinese (Simplified), and based on your feedback we’re looking to expand these to more languages. After upgrading to today’s build, some Insiders may see them – more details coming later.
  • We fixed an issue resulting in Windows Hello not working on the login screen in the previous build (instead of logging in it would prompt you to enter a pin).

Known issues

  • We’re investigating an issue resulting in Settings crashing when invoking actions on certain pages. This impacts multiple settings, including:
    • In Ease of Access, when clicking “Apply” on Make Text Bigger the Settings app will crash and the text size will not be applied.
    • In Windows Security, when clicking hyperlinks the Settings app will crash.
  • If you cannot sign in with any credential and logon fails with error 0xc000005e, rebooting your computer should resolve this.
  • If the update fails with error 0xC1900101, attempting to update again should resolve the issue.
  • Some users may have an issue launching Inbox Apps after updating. To resolve this please check the following thread on the Answers forum: aka.ms/18252-App-Fix.

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.
