Microsoft today has released Windows 10 20H1 preview build 18945 to Insiders in the Fast ring. This build follows up last week’s build 18941 was light on new features and mainly contained fixes and improvements. Today’s build does have a few new features for Insiders like a new Cortana experience and updated File Explorer search. Here is a look at what you can expect.

Windows 10 20H1 Preview Build 18945

New Cortana experience: The company is changing things up with Cortana on Windows 10 20H1 in Beta form. It features a new chat-based UI that allows you to type or speak your queries naturally.

It will also support the following:

  • Cortana now supports both light and dark themes in Windows.
  • We have created a new, less intrusive screen for “Hey Cortana” queries so you can stay in the flow while you work.
  • We have updated Cortana with new speech and language models, and significantly improved performance – making it faster and more reliable than ever before.

Updated File Explorer search: This is now rolling out to all Insiders. This feature was first introduced with build 18894 back in May and only was introduced to a small percentage of Insiders. It’s a more powerful search experience for File Explorer that helps integrate online OneDrive content, for example.

There are also more improvements to Windows Subsystem for Linux (WSL) with the ability to connect WSL 2 Linux networking apps using localhost. There are also Accessibility improvements with this build, namely with Narrator.

In addition to the new features above here is the list of other fixes and system improvements contained in build 18945:

  • We have fixed the issue causing some Insides to experience install failures with error code c1900101 due to a compatibility bug with a storage driver on their device.
  • We’ve made a few fixes to improve reliability when installing a Windows Subsystem for Linux 2 distro.
  • We are extending Windows Defender ATP capabilities beyond the Windows OS and as a result are renaming to Microsoft Defender to reflect our cross-platform approach to endpoint security.
  • We fixed an issue where Settings might crash if you selected Activation under Updates & Security.
  • If your network connection is unexpectedly disconnected, the Miracast banner will now have a close button for you to use if needed.
  • We fixed an issue where the Performance tab of Task Manager wouldn’t expand from a collapsed state if you double clicked on the text.
  • We’ve updated the Details tab of Task Manager so if you right-click a process, Provide Feedback will now be listed after End Task and End Process Tree (rather than between).
  • We fixed an issue where the network icon in the taskbar might show that there was no internet, even though there actually was connection.
  • We fixed an issue impacting Windows Hello reliability in recent flights.
  • We fixed an issue where if you manually updated the DNS server settings in Settings, it wouldn’t apply.
  • We fixed an issue from the previous two flights resulting in mobile hotspot unexpectedly turning off if enabled.
  • We fixed an issue that could result in the system hanging after resume from hibernation.
  • We fixed an issue potentially resulting in the error, “MMC has detected an error in a snap-in and will unload it.” when you try to expand, view, or create Custom Views in Event Viewer.

Remember that 20H1 is an Insider build that will be the feature update we expect to see in the Spring of 2020. Microsoft has announced that 19H2 will basically be a service pack and that is coming this September. So, with Insider builds you can expect a lot of bugs and other issues for both users and developers. Make sure to read Microsoft’s full blog post for all changes, known issues, and workarounds.
