Here's what's fixed, improved, and still broken in Windows 10 build 18252

Microsoft released Windows 10 Insider Preview build 18252 to the Fast ring today, making it the first build from the 19H1 development branch that's not exclusive to those that opted into Skip Ahead. It doesn't contain any major new features, although there are som minor ones.

As usual though, there's a list of fixes, improvements, and known issues. Here's what got fixed and improved:

  • 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).

Here are the 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: ms/18252-App-Fix.

There's still one known issue 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.

As always, you can install today's build by going to Settings -> Update & security -> Windows Update -> Check for updates. If you're not on the Fast ring, you can sign up by going to the Windows Insider Program tab. If you are and you don't want to be, this is your last chance to unenroll before you have to do a clean installation.
