Sep. 26, 2019 / Updated by Bessie Shaw to News

Los Angeles, Calif. - September 24th, 2019 - It's Tuesday today. The tech giant Microsoft introduces its latest Windows 10 20H1 preview build - Build 18990 to Windows Insiders in the Fast ring, which brings a bunch of improvements and bug fixes. Let's take a close look at it.

What’s new in Windows 10 Insider Preview Build 18990 (20H1)

Windows 10 20H1 Preview Build 18990 comes with some notable new features, including:

Enabling automatic restart for UWP apps

Microsoft 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 last month. In Build 18990, 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. You can follow these steps to try it out:

Step 1. Access to Settings > Accounts > Sign-in options and turn on the “Automatically save my restartable apps when I sign out and restart them after I sign in.” option under Restart apps.

Step 2. Start one or more UWP apps, such as Feedback Hub.

Step 3. Sign out and then sign back into Windows.

UWP apps that were started, such as the Feedback Hub, should restart minimized with a taskbar button.

Improving Windows Subsystem for Linux (WSL)

  • 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]

Updating Xbox Game Bar

Microsoft is roll out an FPS counter and achievement overlay to update Xbox Game Bar. The update will come via the Microsoft Store. Just set focus to your favorite game and press Windows + G to get started.

Note: You may have to be joined to receive Game Bar updates via the Xbox Insider Hub app (under Insider Content) from the Microsoft Store to see this update.

Optimizing Windows 10 PC reset using the cloud

From this build, you will have the ability to reset a Windows 10 PC by downloading a new image from the cloud instead of using the existing Windows files stored on the machine. This can be a more reliable way to reinstall Windows and, depending on internet speed, can be faster as well. To achieve a similar result, previously you would have to download Windows and create a USB stick. But because this is built-in to Windows, it doesn’t require the extra steps of creating a USB stick to do the installation.

  • Adjusted the design of the input mode switcher on the taskbar for the Simplified and Traditional Chinese IMEs that the icon glyph was large and blurry.

  • Fixed an issue where some Chinese characters in the Common Standard Chinese Characters dictionary couldn’t be input with the new version of the Simplified Chinese IME.

  • Fixed an issue where, when switching to English input mode and back to Chinese input mode, the punctuations would become Chinese punctuations, even if “Use English punctuations when in Chinese input mode” was enabled with the new version of Simplified Chinese IME.

Known issues in Windows 10 20H1 Preview Build 18990

  • Certain 2D apps (like Feedback Hub, Microsoft Store, 3D Viewer) are incorrectly being treated as having protected content within Windows Mixed Reality. During video capture, these 2D apps block their content from being recorded.

  • When capturing a repro video while filing a bug via Feedback Hub in Windows Mixed Reality, you won’t be able to select Stop video, due to the protected content issue noted above. If you want to submit a repro video, you will need to wait 5 minutes for the recording to time out. If you’d like to file the bug without a repro video, you can close the Feedback Hub window to end the recording and resume filing your bug when you reopen the app in Feedback > Drafts.

  • When viewing Optional drivers in the new section on the Windows Update page, you may notice older drivers showing as available for download. If accepted, they will attempt to install and fail to do so. This is a bug related to revised Windows Update detection logic rather than this new UI. The root cause is understood, and a fix will be available in an upcoming build.

  • Devices configured for dual scan (WSUS and Windows Update) for updates may not be offered new builds in the Fast ring. Selecting Check online for updates from Microsoft Update will scan for updates, but may return with the message, “Your device is up to date.”
