Here's what's fixed, improved, and still broken in Windows 10 build 21313

The Windows Insider program missed a beat last week as the scheduled weekly build of Windows 10 hit a snag, meaning it couldn't be released. Then this week, we missed the Wednesday release again, but we're getting a Friday build instead. Build 21313 is now available to install, and there are actually some notable changes in this one, like removing the legacy version of Microsoft Edge and some improvements to Asian IMEs.

But of course, there's also an array of fixes, improvements, and known issues, which you'll want to know about before diving in. First, there are minor improvements for some of the existing features, including a new icon for Narrator. Microsoft is also changing the version name in Dev channel builds to just say "Dev":

• 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.

  - Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\IdentityStore\LoadParameters\{B16898C6-A148-4967-9171-64D755DA8520}]
  - Value: “Enabled”=dword:00000001
• Reset my PC with the Keep my files option is failing and then returning to its previous state. The Remove everything option will work as expected. We appreciate your patience as we work on a fix.
• We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
• We’re investigating an issue impacting the reliability of Start and other modern apps, which started in recent Dev Channel flights. If you are impacted, you may experience the Start menu layout resetting.
• 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.
• [News and interests] Sometimes the news and interests flyout cannot be dismissed with pen.
• [News and interests] News and interests uses more taskbar space on the left than expected.
• Users may notice Domain networks appearing with the wrong firewall profile which may block some local network services. As a workaround, users may configure the network as private to allow local network traffic. This will be fixed in a future release.
• We’re investigating reports from Insiders that the Chinese text for the lunar calendar in the clock and calendar flyout is no longer displaying properly as of the previous flight.
• After installing this build, you may notice an issue wherein it is not possible to unpin apps from the Start menu. We are working on a fix.

As usual, builds in the Dev channel are in active development and aren't tied to a specific Windows 10 release. The features being added in these builds may show up in the next Windows 10 feature update, but they may end up being delayed or cancelled altogether.
