Hello Windows Insiders, today we are releasing Windows 10 Insider Preview Build 20279 (FE_RELEASE) to Windows Insiders in the Dev Channel. This build is largely the same as Build 20277, but we wanted to test our ability to quickly follow-up a flight with another flight.

Windows Insiders who updated to Build 21277 (RS_PRERELEASE) last week will not be offered this build as they are on a newer build. We are working on getting a new build out to those Insiders soon. We expect to move all Insiders in the Dev Channel back to receiving builds from RS_PRERELEASE sometime after the holidays.

Known issues

• 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.
