Last week Microsoft Released Build 14971 to the Fast Insider Ring, This build is running smooth! Here’s what’s changed: Native support for epub files in Edge & Paint 3D are my favorites!
What’s new in Build 14971
Read EPUB books in Microsoft Edge: The reading experience will get even better with the Windows 10 Creators Update! In addition to providing a great reading experience for PDF files – you can now read any unprotected e-book in the EPUB file format with Microsoft Edge. When you open an unprotected e-book in Microsoft Edge, you will be taken into a customizable reading experience where you can change the font and text size and choose between 3 themes: light, sepia, and dark. As you read, you can leave bookmarks. To navigate through an e-book, you can use the table of contents or seek bar at the bottom of the browser. And you can also search for words or phrases and use Cortana to define specific words.

You can download and read unprotected e-books from places like Feedbooks, Project Gutenberg, Free eBooks (requires sign-up), ePubBooks (requires sign-up), Open Library and even our own Microsoft Press. Try out reading an e-book in Microsoft Edge and let us know what you think!
Bringing 3D to Everyone via the Paint 3D Preview app: Starting with this build and going forward, the Paint 3D Preview app is now included as part of Windows 10. Opening Paint from Start will now take you to the Paint 3D Preview app. Please try it out and let us know what you think we should improve or add next! Currently, Paint 3D Preview is only available in English (aka, regardless of your display language, the text will be in English) – support for other languages will be coming soon. Remix 3D Preview, the community counterpart to Paint 3D Preview, is expanding to Austria, Belgium, Denmark, Germany, Ireland, Netherlands, Norway, Sweden, and Switzerland for Windows Insiders today! Remix 3D Preview is currently only available in English but we will continue to expand our region and language support. You can check it out at Remix3D.com and from within the Paint 3D Preview app.
PowerShell in the Shell: In an effort to bring the best command line experiences to the forefront for all power users, PowerShell is now the defacto command shell from File Explorer. It replaces Command Prompt (aka, “cmd.exe”) in the WIN + X menu, in File Explorer’s File menu, and in the context menu that appears when you shift-right-click the whitespace in File Explorer. Typing “cmd” (or “powershell”) in File Explorer’s address bar will remain a quick way to launch the command shell at that location. For those who prefer to use Command Prompt, you can opt out of the WIN + X change by opening Settings > Personalization > Taskbar, and turning “Replace Command Prompt with Windows PowerShell in the menu when I right-click the Start button or press Windows key+X” to “Off”.
Fun fact! It’s PowerShell’s 10 year anniversary this week. Hop over to Channel 9 to see some of the videos we’ve been sharing about it. If you’re looking to learn more about unleashing the “power” in PowerShell, this page is a great resource.
Improved Typing Experience with Japanese and Chinese Input Method Editors (IMEs): This build includes many improvements in this space – here are some of the highlights:
- Improved Chinese IME reliability. In particular, we fixed an issue where the IME might crash due to an incompletely downloaded or corrupted dictionary file
- Improved Conversion Accuracy for the Japanese IME. We also fixed various issues, in particular, when conversion was used mixed with prediction, and an UX issue when trying to change phrase segmentation.
- Improved resource usage when typing with the Japanese IME. In particular, we fixed an issue that could result in unexpected graphic glitches after using the IME for an extended period of time.
Get Office (Beta): We’ve heard your feedback about the Get Office app, and today we’re happy to announce Get Office version 2.0 for Insiders in the Fast ring! (Well, technically, version 17.7614.2377.0). Whereas before Get Office was largely a collection of links to help you get started with Office, the new and improved app will help you explore and manage your Office experience. Easily discover and launch apps and see all your recent Office documents in one place! We still have the familiar help links, but we’ve redesigned the experience to make easier to find what you’re looking for. As you try out the new app, please log feedback – we’d love to hear your thoughts!

Other changes, improvements, and fixes for PC
- First introduced to Insiders in Build 14926, the experimental “Snooze” action on a tab in Microsoft Edge which provides you with a way to set a Cortana reminder on the website you are viewing is no longer available. Based on data we gathered and feedback we received, we decided to remove it from the product and re-evaluate the feature for a future release.
- We’ve improved reliability when using the protractor and inking in Sketchpad.
- We’ve updated some of our desktop wizards (including “map a network drive” and “extract from zip”) to now be proportionally sized when moved across monitors.
- We fixed an issue where Magnifier’s keyboard shortcuts sometimes wouldn’t work on the Lock screen.
- We fixed an issue that could result in sometimes not being able to completely remove files in the Windows.old folder using Disk Cleanup.
- We have enabled OAuth support for Yahoo Mail accounts. This will improve sync reliability for those accounts, and provide a more secure experience in the Outlook Mail app.
- We fixed an issue where trying to shut down the PC while certain Device Manager dialog boxes were open would result in the PC being stuck at the “Restarting…” screen.
- We fixed an issue where, as closing multiple tabs with middle click in Microsoft Edge, the width of the tabs might change, resulting in potentially unexpectedly closing the wrong tab.
- We fixed an issue where the copy link option when right-clicking a hyperlink in Microsoft Edge wasn’t work.
- We fixed an issue where, if you changed the size of the Microsoft Edge window, and then closed the app by closing the final tab, the next time Microsoft Edge is launched it would once again be the default size, rather than retaining the preferred window size.
- We fixed an issue where pinned tabs in Microsoft Edge were not being restored.
- We’ve made a number of translation improvements, including for Chinese speakers fixing a translation error in the dialog that appears when installing multiple fonts at once, as well as one in Settings > System > Battery. If you see any other translations that aren’t as you’d expect, please log feedback – we’re listening!
- We fixed an issue where, if you already hand a notification expanded in the Action Center, clicking the chevron to expand a second notification would result in it expanding then immediately closing.
- We fixed an issue where preferred Start menu width might not be preserved after rebooting.
Known issues for PC
- Navigating to Settings > System > Battery will crash the Settings app.
- Using keyboard monitor hotkeys to adjust brightness won’t work as expected. Desired brightness change could be done via the Action Center or by going to Settings > System > Display.
- Apps such as Store, Photos, and People may launch on their own after your PC has been inactive for a period of time. To stop these apps from launching on their own, un-maximize the app before closing it.
- Double-clicking on an Excel document to open it from File Explorer will crash Microsoft Excel. The workaround is to open the document from within Excel.
- Microsoft Studios games like Microsoft Sudoku, Jigsaw, Minesweeper, Taptiles, and Treasure Hunt may freeze at the splash screen on launch.
- As we have previously announced we are working on the Windows Holographic Shell that is going to be included in the upcoming Windows 10 Creators Update. In today’s flight you will see the Windows Holographic First Run app. While you will be able to launch the app and walk through the first few screens, it won’t detect any hardware. This app and the Windows Holographic Shell is still under active development here at Microsoft and with our partners.





We are also introducing Stencils. Windows Ink protractor tool combines functions of both protractor and compass into one – now you can draw an arc or a complete circle of an arbitrary size with little effort. A familiar two-finger pinch gesture resizes the protractor to the desired size and a degree readout follows your pen, mouse, or finger as you draw along the side of the protractor displaying arc degrees. In this preview build, ruler also got a small update – its degree readout shows a numerical value of the angle, making drawing angles even easier.
Simplified, more familiar camera interface (PC & Mobile): The Camera app received a big update this week for Insiders. We’ve redesigned the Camera interface for ease and accessibility. Check out some of our new features:
You can now experience the magic of living images on your Surface, now enabled on Surface Book, Surface Pro 4, Surface Pro 3, and Surface 3! With living images, extend your still captures with a snippet of video. These are created automatically whenever your shots feature motion—just navigate to Settings and turn on Capture living images.
Simplifying your developer experience (PC): We’ve done some underlying work, and now you’ll no longer have to reboot your PC after turning on Developer Mode! This means that you can start using Device Portal and Device Discovery as soon as the Windows Developer Mode package has finished installing, rather than having to reboot first.
However, we know that some of our Insiders prefer even more control over their experience, so for those Insiders (and power users) we have added a new Advanced Gestures Configuration page. The page can be accessed via a link at the bottom of Touchpad settings page.
The Advanced Gestures Configuration page has more configuration options, including hooking gestures up for next/previous song, creating/deleting virtual desktops, or snapping windows. In addition to these new options, we’ve also updated the Touchpad settings to include reference diagrams to remind you of what to expect when you swipe with three or four fingers in a particular direction.
We are also continuing to move functionality from the Wi-Fi (legacy) screen to the new Wi-Fi settings screen on Mobile. After you turn off Wi-Fi, choose a time under Turn Wi-Fi back on to have it turn on automatically after the amount of time you choose. Based on what we heard from customers in the Windows 10 Anniversary Update, we changed the default setting from “In 1 hour” to Manually in this build.
Photos app update: With the latest Photos app update on your PC, the Photos app on your PC is now more beautiful and easier to navigate!


Form field navigation in Narrator: We are excited to announce that this build introduces form field navigation to Narrator.
