Microsoft Releases Windows 10 Build 20257

Microsoft today is releasing Windows 10 preview build 20257 to Insiders in the Dev Channel. Here’s a look at what’s new.

Microsoft today is releasing Windows 10 preview build 20257 to Insiders in the Dev Channel. This build follows up last week’s build 20251. Today’s release includes some new features for the Your Phone app. As well as a list of fixes and improvements. Here’s a look at what you can expect.

Windows 10 Build 20257

The Your Phone update is introducing a multi-apps experience. “You can experience the power and convenience of running multiple Android mobile apps side by side on your Windows 10 PC on supported Samsung devices. Apps will launch in separate windows enabling you to interact with multiple apps at the same time even if the Your Phone app is not open.”

Here are the changes and improvements in this build:

  • 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.

And here is the list of fixes contained in today’s new release:

  • 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.

Remember that Insider builds are meant for coders, IT admins, and Windows 10 enthusiasts who want to test new features and submit feedback to Microsoft.

These builds are not meant for inexperienced users. They are also not meant to run on your primary production machine. Insider builds contain many known stability issues that can cause your system to become unstable or even crash.
