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.
