What you need to know

  • Windows 10 build 20257 is now available for Dev channel Insiders.
  • This build brings lots of fixes and a slight tweak to the way Start Menu tile theming works.

Microsoft rolled out another new Windows 10 Insider build for the Dev channel today, bringing the build number to 20257. This week, the build is mostly concerned with fixes. However, Microsoft has also tweaked the way Start Menu theming is done.

The Start Menu tile theming logic will now no longer make adjustments based on contrast ratio. However, this tweak doesn't apply to Microsoft Edge PWAs that are pinned to Start.

Here's a look at the full list of changes and fixes included 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.
  • 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.

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.
