Here's what's fixed, improved, and still broken in Windows 10 build 20277

It's Wednesday, and as we've gotten used to by now, that means it's time for Microsoft to release a new build of Windows 10 for Insiders enrolled in the Dev channel. After a six-week-long drought in new features, build 21277 has finally brought some good news in the form of x64 emulation for ARM devices like the Surface Pro X, among other things.

However, by default, you'll still getting be build 20277 from the fe_release branch, which only gets a couple of fixes, just like we've been getting for the past six weeks. This time, there are only two fixes:

  • We fixed an issue that could result in the WinRE volume label being lost after multiple upgrades.
  • We fixed an issue that could result in apps failing to update with error code 0x80073D02.

As usual, there are still a few known issues, which are to be expected in development channels like this, Here's what to look out for:

  • 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 working on a fix for an issue resulting in some users 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 working on a fix for an issue where, in recent Dev Channel builds, 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.

As we near the end of the year and the holiday season, there may not be many more builds in the coming weeks, but things should pick back up in 2021. Microsoft has been reported to be redesigning the UI of the operating system, plus bringing Android app emulation to the platform, next year, and we may start to see some of that work as we head into it. For now, the most exciting stuff is only for ARM devices.
