Microsoft releases Windows 10 Build 20277

We're used to Microsoft rolling out a new Windows 10 Dev Channel build on a weekly basis, but this time around it has something different for us -- two Dev Channel builds, from different branches. It’s like a choose your own adventure.

The first of the new flights, Build 20277, comes from the usual FE_RELEASE branch and sports a handful of fixes and known issues.

The fixes in this build are:

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

Known issues are:

  • Microsoft is 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. Microsoft is continuing to work on polishing this experience.
  • Microsoft is 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.
  • Microsoft is 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.
  • Microsoft is 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.
