Announcing Windows 10 Insider Preview Build 21390
Hello Windows Insiders, today we are releasing Windows 10 Insider Preview Build 21390 to Windows Insiders in the Dev Channel.
Changes and Improvements
- As part of our ongoing iconography improvements, Task Manager and MSI installers now have new Fluent icons.
- You can now set Windows Terminal Preview as your default terminal emulator on Windows – please see this blog post for details. This requires Windows Terminal Preview version 1.9 (or higher).
Fixes
- We fixed an issue causing the news and interests text on the taskbar to appear blurry on some resolutions and scaling factors.
- We fixed an issue resulting in certain punctuation not being displayed correctly when the display language was Chinese.
- We fixed a svchost.exe crash related to cdp.dll that some Insiders have been experiencing in recent builds.
- We fixed an issue impacting Start reliability in recent flights.
- We fixed an issue where when using dark mode, the text in the File Explorer search box would be black on a black background. Please note this only addresses this dark theme issue in File Explorer, we are continuing to investigate a second issue impacting dark theme when using Search in the taskbar.
- We fixed an issue in recent flights where a folder might not retain keyboard focus after being renamed in File Explorer.
- We fixed an issue resulting in Task Manager showing the incorrect icon for some processes.
- We fixed a second issue causing some devices to fail when updating to this build with error code 0xc1900101. If you continue to receive this error code when attempting to update, please file a new feedback item.
Known issues
- The Windows Camera App currently does not respect the default brightness setting set via the new Camera Settings page.
- We’re investigating an issue where Search results are unexpectedly no longer following dark theme as of recent flights.
- [News and interests] We’re investigating an issue where the flyout may occasionally flash in the top left corner of your screen after clicking the button on your taskbar.
An update on feedback policies
In an effort to improve feedback relevance, in the coming weeks we will be implementing a change to only retain and display the last 15 months worth of feedback in the Feedback Hub. This will not impact Achievements, Quests, or Collections. If you have feedback older than the retention period that you would like us to consider, please take a moment to create a new feedback item for it. Best practices for creating actionable feedback for the engineering team are available here if needed.
Important Insider Links
You can check out our Windows Insider Program documentation here, including a list of all the new features and updates released in builds so far. Are you not seeing any of the features listed for this build? Check your Windows Insider Settings to make sure you’re in the Dev Channel. Submit feedback here to let us know if things weren’t working the way you expected.
