What you need to know

  • Windows 10 build 18990 is now available for Windows Insiders on the Fast ring.

Windows 10 20H1 build 18990 is now available for Fast ring Insiders. This update brings a couple of new features to the fore, but is mostly focused on bug fixes and performance improvements.

The most notable new feature is the ability to set UWP apps to automatically restart when signing back in to a PC. Microsoft rolled out this ability for registered desktop apps in a prior build, but it now works with UWP apps as well.

There are also some improvements to the Windows Subsystem for Linux and more. Here's a look at all of what's new and fixed in this build.

What's new in build 18990

Enabling automatic restart for UWP apps

  • Last month, we introduced a new separate setting to control if registered desktop apps from your previous sign-in session are restarted when signing back in to Windows. In the latest Insider Preview builds, in addition to registered desktop apps, when you opt into this setting, the majority of open UWP apps are now also automatically restarted as well! To reduce sign-in time, UWP apps are restarted minimized, in a suspended state, giving Windows and other apps more resources to get started.

Windows Subsystem for Linux (WSL) improvements

  • Improved the performance for directory listings in \wsl$
  • [WSL2] Injected additional boot entropy [Github Issue 4461]
  • [WSL2] Fixed Windows interop when using su / sudo commands [Github issue 4465]

Xbox Game Bar Updates

  • In case you hadn't seen, we're starting to roll out an FPS counter and achievement overlay! Thanks to everyone who shared feedback about this. The update will come via the Microsoft Store. Just set focus to your favorite game and press WIN + G to get started.

Reset your PC from the cloud

  • Earlier today in our Windows Insider webcast, we had the Deployment Team as guests to talk about the new feature that is coming with 20H1 that allows you to reset your PC using the cloud.
