Microsoft releases Windows 10 Insider Preview Build 20270

Microsoft have released Build 20270 for Windows Insiders on the dev channel. This build is from the FE_RELEASE branch which means we still don’t have the new features which we had in the PRE_RELEASE branch.
UPDATE: Here is my hands on video

Here are the changes, fixes and known issues with build 20270:

Changes and Improvements

The new “Advanced View” checkbox in Optimize Drives is now up and running and checking it will display volumes previously not visible in this window (for example system and recovery partitions).

Using the touch keyboard in a portrait posture on a 2-in-1 touch device now supports split keyboard mode. (This was released to Windows Insiders in the Beta Channel as part of the recent Windows Feature Experience Pack update.)


We fixed an issue resulting in some dialogs, such as Properties, displaying black text on dark backgrounds in recent flights.

We fixed an issue that could result in certain apps unexpectedly closing when clicking the Maximize button in recent builds.

We fixed an issue resulting in printers with Japanese characters in their names not displaying correctly in Printers & Scanners Settings.

We fixed an issue that could result in some delay logging into your PC on devices with a large number of users.

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.
