What you need to know

  • Windows 10 build 21313 is now available in the Dev Channel.
  • It includes the new Microsoft Edge, improvements to news and interests, and more.
  • The build is not available for arm64 PCs.

After taking a week break, Microsoft is back with a new Windows 10 Insider Preview build for testers in the Dev Channel to submit feedback about. Today's build is 21313, and features a handful of minor changes and enhancements in addition to a plenty of new fixes to test.

Build 21313 includes updates to the "news and interests" widget, now being available to anyone anywhere in the world instead of specific regions. Elsewhere, MIcrosoft is finally replacing the legacy Edge client with the new Chromium version of Microsoft Edge in the Dev builds.

Here's the complete list of new changes:

  • Based on feedback, and to align with the fact that Dev Channel builds are not matched to a specific Windows 10 release, we have updated the displayed version name to now be Dev.
  • We heard feedback that it wasn't clear how to turn off news and interests if this was your preference. To help address this, we changed the "Hidden" option in the taskbar context menu to now say "Turn off" to make this functionality clearer.
  • Based on feedback, we've made some small adjustments to the new app launch animation to improve speed and make it a little smoother.
  • The improvement to the candidate bar on the touch keyboard announced last week where it displays 5 candidates maximum and centers them into position above the keyboard has begun rolling out.
  • The new voice typing experience that was announced back in September has begun rolling out to all Insiders in the Dev Channel. Press the Windows key plus H if you'd like to try it out in one of the supported languages.
  • The change to enable pinning items in our updated clipboard history design (inside the emoji picker) is now rolling out to all Insiders in the Dev Channel.
  • We've made a few more updates to our emoji search teams based on feedback, including that programming will now return the 3 technologist emojis and RIP will now return the tombstone emoji. We've also updated the search in Russian so that emoji with the letter ё in their keywords can now also be found by using the letter e. Please keep the feedback coming!
  • We are removing the capability to copy and paste a screen snip directly into a folder in File Explorer for now due to an issue discovered thanks to the feedback from Windows Insiders. We hope to re-enable this capability in a future update after we address this issue. (This change was also released to Windows Insiders in the Beta Channel as part of the recent Windows Feature Experience Pack update.)
  • As part of our continued iconography work, this build introduces a new design for our Narrator icon.

  • We fixed an issue resulting in some Insiders experiencing an IRQL_NOT_LESS_OR_EQUAL bugcheck when attempting to upgrade to a newer build.
