Microsoft has released a new Windows 10 (20H1) build to Windows Insiders in the Fast ring.

“Today we’re releasing Windows 10 Insider Preview Build 18980 (20H1) to Windows Insiders in the Fast ring,” the Microsoft announcement notes.

New features include:

Windows Subsystem for Linux (WSL) improvements. WLS is finally coming to ARM-based PCs. In addition, you can now set your distribution’s default user using the wsl.conf configuration files in /etc, and this release contains multiple bug fixes, including a long-standing issue for legacy Windows symlinks.

Cortana improvements. Starting with this build, all users will see the Cortana icon in the taskbar and can access the new Cortana app. In the future, users will be able to Cortana if they speak a supported language, regardless of their OS display language. Today, Cortana only supports U.S. English but Microsoft claims that turning Cortana into a standalone app will help it add languages in the future. “We expect to support the same set of regions and languages we currently support in retail by 20H1 launch,” Microsoft says, without explaining what those regions and languages are. So I’ll do it: Today, Cortana supports Australia: English, Brazil: Portuguese, Canada: English/French, China: Chinese (Simplified), France: French, Germany: German, India: English, Italy: Italian, Japan: Japanese, Mexico: Spanish, Spain: Spanish, United Kingdom: English, and United States: English.

Optional Features settings improvements. The A/B testing is over so now all Insiders can test the new Optional Features section in Settings.
