Microsoft Delivers Windows 10 Insider Preview Build 14977 for Mobile Only

After taking the Thanksgiving week off, Microsoft today delivered a new build of Windows 10 to the Insider Preview Fast ring. But it’s available only for Mobile.

“We will not be releasing a PC build this week due to a blocking bug that could result in broken apps after updating to a new build,” Microsoft’s Dona Sarkar explained. The previous Insider build for PC was 14971, which was released on November 17. That build was only for PC, not Mobile.

Here’s what’s new in Windows 10 Insider Preview build 14977 for Mobile.

Read EPUB books in Microsoft Edge. This debuted in build 14971 for PC, and now it’s available on Windows phones, too: You can now read unprotected e-books in the EPUB file format in the Microsoft Edge web browser. It includes a customizable reading experience with font and text size options and three themes: light, sepia, and dark. You can also bookmark your location, navigate with a table of contents, and search. It even works with Cortana. (Microsoft notes that you can find free e-books from Feedbooks, Project Gutenberg, Free eBooks (requires sign-up), ePubBooks (requires sign-up), Open Library and Microsoft Press.)


Other changes, improvements, and fixes. Microsoft lists a number of other changes, improvements, and fixes in this build, including a new rendering technology for UWP which may result in some visual glitches, the ability of third party alarms to ignore Quiet Hours, new notification settings, OAuth support for Yahoo Mail accounts for improved sync reliability, and more. Check out the full list for more information.

As you might expect, there are also some known issues in this build, including one serious issue: If you attempt to install new languages, keyboards, and speech packs on your phone, the download may get stuck and never complete.

    New UWP rendering engine? Oooooooooh...

    Remember, the great thing about having the Edge web browser as a UWP app is that they can update it through the store, and not have to do it through OS updates.

      LOL. If only you knew. That's what all the Microsoft fans keep saying, but Microsoft has never said or done that that, and indeed I have never seen Edge get updated through the Store. Instead Edge gets updated with the OS just like "Internet Exploder".

      Microsoft even has tacitly admitted that they've messed this up, because they mentioned that they are now working to make Edge's front-end be updatable through the Store. The backend? Well that's apparently tied to the OS and so that can't be updated via the Store. So Edge is sort of going to split into two with two different upgrade paths and combinations for the same browser.

      Kill me.

      So they can now easily update Edge on phone so it actually renders full web pages without the "this page is effed, so we're crashing" excuse? I can't wait...
