Microsoft has released Windows 10 Insider Preview Build 20257 (FE_RELEASE) to Windows Insiders in the Dev Channel.
Changes and Improvements
- Based on feedback, we’re updating our Start menu tile theming logic such that the tile background for Win32 apps will no longer adjust based on detected contrast ratio, except in the case of pinned Microsoft Edge PWAs.
Fixes
- We fixed an issue starting with Build 20236 where installing games from the Store to a secondary non-OS drive would result in the secondary drive becoming inaccessible.
- We fixed an issue causing some devices to experience a DPC_WATCHDOG_VIOLATION bugcheck in recent builds.
- We fixed an issue resulting in some apps crashing on launch in the previous flight, including Microsoft Jigsaw and Microsoft Minesweeper.
- We fixed an issue resulting in File Explorer having a transparent line across the top when maximized on systems with multiple monitors.
- We fixed an issue resulting in win32 app titles being unexpectedly highlighted in the title bar after enabling and disabling high contrast.
- We fixed an issue where the windows.old folder is not completely deleted when performing disk cleanup.
- We fixed an issue where if you reset your PC then and re-connected your MSA, then your MSA picture might never sync down.
- We fixed an issue impacting Windows Hello Face recognition if the device was trained in a different orientation than the orientation used at unlock time.
- We fixed an issue where setting up a kiosk (assigned access) account wouldn’t work the first time you tried, only subsequent tries.
- We fixed a deadlock that could result in unexpected CPU usage. If you continue experiencing other performance issues, please take a moment to file feedback including details about the issue you’re seeing, and a performance trace. More info about collecting a repro trace is available here if needed.
- We fixed an issue resulting in recently some apps being slower to accept keystrokes into text fields.
- We fixed an issue that could result in links from apps failing to launch the browser.
- We fixed an issue from the last couple flights that could result in audio playback unexpectedly stopping.
- We fixed an issue that could result in not hearing audio after streaming certain content then turning your Bluetooth headset off and back on.
- We fixed an issue that could result in Movies & TV failing to play some recorded HDR videos with error 0x80004001.
Known issues
- We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
- Live previews for pinned sites aren’t enabled for all Insiders yet, so you may see a grey window when hovering over the thumbnail in the taskbar. We’re continuing to work on polishing this experience.
- We’re working on enabling the new taskbar experience for existing pinned sites. In the meantime, you can unpin the site from the taskbar, remove it from the edge://apps page, and then re-pin the site.
- We’re investigating reports that some users are seeing error 0x80070426 when using their Microsoft account to sign into various apps. If you encounter it, rebooting your PC may resolve this.
- We’re investigating an issue where, after taking this build, no drives appear under Settings > System > Storage > Manage Disks and Volumes. As a workaround, you can manage your disks in the classic Disk Management tool.
- We’re investigating reports that some screens incorrectly have black text on dark backgrounds when dark theme is enabled.
Updates for developers
The Windows SDK is now flighting continuously with the Dev Channel. Whenever a new OS build is flighted to the Dev Channel, the corresponding SDK will also be flighted. You can always install the latest Insider SDK from aka.ms/InsiderSDK. SDK flights will be archived in Flight Hub along with OS flights.
