Fixes and known issues in Windows 10 Build 16215

Microsoft today released yet another Windows 10 Insider Preview version. Windows 10 build 16215 which represents the upcoming Windows 10 Fall Creators Update, code name "Redstone 3", is available now for Fast Ring Insiders. Here is the list of fixes and known issues.

Changes, improvements, and fixes

  • Language Packs via Settings > Time & language > Region & language are available again starting with this build.
  • The issue causing updating to the latest builds to get stuck at 12% should be fixed. If you still hit this, please send us feedback in Feedback Hub so the team can investigate.
  • We fixed the issue causing you to be unable to type in your password to log in to any UWP apps such as Netflix, Twitter, Facebook, Instagram or Messenger apps.
  • We fixed the issue causing Outlook 2016 to hang on launch due to an issue where the spam filter gets stuck reading the Outlook Data File and the UI waits indefinitely for it to return.
  • We fixed an issue from the previous flight where Microsoft Edge would crash when enabling or disabling extensions.
  • We’ve removed the power option to “update and shutdown” for now as it wasn’t working.
  • You may see Recovery Drive tool show up under “Recently added” on Start after updating to this build. We have made a change that makes the tool, previously only accessible via Control Panel, to now be available in the Windows Administrative Tools folder in Start.
  • We fixed an issue where an unexpected Wireless Display Media Viewer app with a blank icon was visible in Start after upgrading on certain devices.
  • We’ve made some improvements to our facial recognition, along with a new toast you’ll see prompting you to further train Windows Hello if having issues signing in when a large amount of backlighting detected.
  • We fixed an issue resulting in Windows Hello Face failing to work on the previous flight for a large number of non-English languages.
  • We fixed an issue resulting in games such as Civilization VI, Galactic Civilizations III, and Expeditions: Viking failing to launch on recent builds.
  • We fixed an issue where inbox UWP app icons were overscaled in Cortana search results.
  • We’ve heard your feedback, and have adjusted the text in our prompt to initiate cross device notifications from saying “Trust this PC?” to now say “You got a message on your phone. Want to see phone messages on this PC too?”.
  • We fixed the issue causing some people to hit Error 0x8000ffff while trying to launch an isolated Edge session in Windows Defender Application Guard.

Known issues

  • Features that are delivered on-demand from Windows Update such as Developer Mode, .NET 3.5, and Speech Packs will not be available for this build. If you are a developer and require Developer Mode – please ensure it is enabled BEFORE taking this build. 
  • On some PCs with enterprise configurations, you may not be able to open PDFs in Microsoft Edge on this build. As a workaround, you can download PDFs and open them with a third party reader or the Reader app from the Windows Store.
  • Microsoft Edge may load web pages at the wrong scale factor (highly zoomed in) on some devices with high density displays. As a workaround. switching to another tab and back should resolve this problem.
  • Some PDFs may open in a cropped view (zoomed in) in Microsoft Edge, and part of the content may be inaccessible to the user. Additionally, input to these PDFs may be offset to the wrong location on screen. As a workaround, you can download PDFs and open them with a third party reader or the Reader app from the Windows Store.
  • After upgrading, inbox apps that are the same version on the downlevel OS and uplevel OS will disappear from Start. If you are impacted by this, please go to Settings > Apps > Apps & Features, select the impacted app, tap “advanced options”, click reset, and that should fix it.
  • We’ve made a fix to address your feedback that PDFs aren’t opening in Microsoft Edge. This will resolve the issue for most Insiders, however we’re still investigating one issue specific to those with Windows Information Protection (EDP) enabled. We’re working to address this as soon as possible in an upcoming flight.
  • New Windows Mixed Reality developers need to install build 16193 or the Windows 10 Creators Update (Build 14939), plug in the Windows Mixed Reality headset and set up Mixed Reality, then upgrade to the latest FAST build for the best development experience. If you update to Build 16215 without setting up Mixed Reality, you will not be able to download Mixed Reality software.
  • You will end up with multiple copies of each printer after upgrading. Only the copy with the highest number will work.
  • Wi-Fi will get turned off on certain devices like the Surface Pro 1 and Surface Pro 2 and some USB devices and won’t work due to a driver issue. To get Wi-Fi working again, you will have to roll-back to the previous build.
  • If you’re using a Chinese IME and try to type in Cortana, it will hang Cortana and not work.
  • Some UWP apps such as Twitter will crash on launch.
  • After updating to this build, Microsoft Text Input Application might appear on your All apps list and when you try to open it, it opens as a blank window.
  • The mini surveys we call SIUFs from Feedback Hub will not work on this build but please send us feedback as you normally would for this build!

  1. For some reason, no mention is made of one key problem that is afflicting windows 10; that of consumption of battery power when fully shut down.

  2. Disk Cleanup -> Clean up System Files is not working on build 16125 for me. Anyone else having this issue?

    You click the Clean Up System Files button and the dialog just vanishes and never returns.

  3. I had an issue with printers. In Edge I could view the PDFs. I tried to print and was told the printers could not be found. They were installed. But at this point every other program reported the printer que was full. I also could not open the downloaded PDFs with any program. I did a restart and the printers worked but PDFs could not open. I ended up emailing the PDFs to my wife and getting her to print them from her phone (wireless connection to printer her at the house). Upon opening Edge and trying to print something from Edge the problem reoccurred.

    The other big issue is scaling. I am fine with 150% in my 4k. Everything was fine. Until this update. At this point I have several programs with extremely small menus and even clicking a menu item is a problem as it will select where I am at and then move to another menu bar selection itself off to the left away from the cursor. Every one of these programs, Photoshop, Steam, Origin, Maya, and a few others.

    And in Edge I get random sizing on websites. So I have MSN set to 100% and it looks fine. I go to another page and it is fine. I come back to MSN and it is at 100% and looks small. So I resize to 125% and it looks fine. Then I move to another site and come back. And MSN is back to looking small (actually a little fuzzy each time probably due to sizing). This time however the option shows 83% and I have to increase it to 100%. This happens in several other sites I go to as well. Plus it is very unresponsive at times when Firefox, Opera, Chrome, and Vivaldi are fast and responsive. Easy to test as Edge browser problem for me.

    I have seen both desktop and store app programs not even start or crash. Just not sure why this update seems so bad for me. Cannot wait for the next update and hopefully some fixes that help.
