Hello Windows Insiders, today we’re releasing Windows 10 Insider Preview Build 18990 (20H1) to Windows Insiders in the Fast ring.

IMPORTANT: As is normal with pre-release builds, these builds may contain bugs that might be painful for some. If you take this flight, you won’t be able to switch Slow or Release Preview rings without doing a clean-install on your PC.

If you want a complete look at what build is in which Insider ring, head over to Flight Hub. You can also check out the rest of our documentation here including a complete list of new features and updates that have gone out as part of Insider flights for the current development cycle.

Not seeing any of the features in this build? Check your Windows Insider Settings to make sure you’re on the Fast ring. Submit feedback here to let us know if things weren’t working the way you expected.

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. To try it out:

Go to Settings > Accounts > Sign-in options and turn on “Automatically save my restartable apps when I sign out and restart them after I sign in.” under “Restart apps”. Start one or more UWP apps, such as Feedback Hub. Sign out and then sign back into Windows.

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

Thank you to everyone who shared feedback about the design of the input mode switcher on the taskbar for the Simplified and Traditional Chinese IMEs. We’ve adjusted the design based on your feedback that the icon glyph was large and blurry.

We 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.

We 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.

We fixed an issue where the new version of Simplified Chinese IME candidate window would sometimes not appear.

Known issues

There has been an issue with older versions of anti-cheat software used with games where after updating to the latest 19H1 Insider Preview builds may cause PCs to experience crashes. We are working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. To minimize the chance of running into this issue, please make sure you are running the latest version of your games before attempting to update the operating system. We are also working with anti-cheat and game developers to resolve similar issues that may arise with the 20H1 Insider Preview builds and will work to minimize the likelihood of these issues in the future.

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.” We’re working on a fix for a future flight.

The Bug Bash starts tomorrow!

Running from Sept. 25th to Oct. 2nd, the Bug Bash is a week–long event that takes place both for Insiders and Microsoft employees to help this release ship with quality. Starting at midnight (PDT), you’ll see Bug Bash Quests light up in the Feedback Hub, continuing throughout the span of the week. More details are available in our coming soon announcement.
