Another week, another Insider Preview build for us to get our hands into. Today's build is 15228 for Mobile and 16232 for PC, and as usual is packing new features and changes for PC and nothing worthy of note for Mobile. These builds are available in the Fast ring.

The last two insider Preview builds for PC have been jam packed with new features, so today's build won't be as huge as the builds we've had previously, but there are still several noteworthy changes.

It's worth noting that with this new build for PC, Microsoft will no longer be flighting new inbox app updates. Microsoft explains:

In order to provide Windows customers with the highest quality inbox apps possible, we will pause testing new versions of our inbox apps with Windows Insiders. This means that Insiders will not receive app updates from the Windows Store for our inbox apps that are newer than the apps included in the build. Insiders may notice that some features we were testing in our inbox apps – including recent updates to the Photos app – will temporarily disappear. This is because some of our inbox apps won't have all the latest new features without getting an update from the Store. It is critical that Insiders are experiencing the same version of Windows that will be released as the default version for all Windows users. Insiders will once again start receiving app updates in the very near future. As always, your feedback will help us tremendously to define the overall Windows experience and insure the quality of the Windows 10 Fall Creators Update is excellent for our customers.

What's new for PC?

Windows Defender Application Guard (WDAG)

  • Giving you access to all the rich features in Microsoft Edge while using Application Guard: Building on our work in Build 16188, we have added support for Microsoft Edge data persistence while using Application Guard. Once enabled, data such as your favorites, cookies, and saved passwords will be persisted across Application Guard sessions. The persisted data will be not be shared or surfaced on the host, but it will be available for future Microsoft Edge in Application Guard sessions.

  • How to take advantage of Data Persistence when using Microsoft Edge with Application Guard: You enable Data Persistence for Microsoft Edge in Application Guard using Group Policy. Note that Data Persistence for Application Guard with Microsoft Edge sessions is not enabled by default. To enable data persistence, close all Microsoft Edge windows and update the Windows Components > Windows Defender Application Guard policy to turn on data persistence
  • How to find your Favorites after you close Edge with Application Guard: Since you have enabled Data Persistence using Group Policy for Application Guard, the site you saved to your Favorites will be available for later use, with Microsoft Edge in Application Guard, even after reboots as well as build to build upgrades of Windows.

Introducing Exploit Protection

  • We're excited to announce that starting with this build you can now audit, configure, and manage Windows system and application exploit mitigation settings right from the Windows Defender Security Center! You don't need to be using Windows Defender Antivirus to take advantage of these settings.

Introducing Controlled folder access in Windows Defender Antivirus

  • In this build, we're making it easier for you to protect valuable data from malicious apps and threats, such as ransomware. To enable the feature, search for and open the Windows Defender Security Center from Start, go to the Virus & threat protection settings section, and set the switch to On

  • Controlled folder access monitors the changes that apps make to files in certain protected folders. If an app attempts to make a change to these files, and the app is blacklisted by the feature, you'll get a notification about the attempt. You can complement the protected folders with additional locations, and add the apps that you want to allow access to those folders.

What's new for Mobile?

  • We have fixed notifications (SMS, Calendar) with all Fitbit trackers.
  • We have fixed crashes reported while using Photos app.
  • We have fixed a deployment issue in where if an admin uses ActiveSyncCSP to provisioning email account on device running the Windows 10 Creators - Update without providing a valid password, and the email server enforces a limited number of denied access retries, then the server will lock out the email account.
  • We have improved battery performance by fixing a bug in a scenario where 30% more power was used during Camera app preview and capture mode.
  • Some Insiders provided feedback that playing video on phone resulted in a black flash and/or stuttering when in landscape mode. We have fixed this issue.
  • We have improved Bluetooth connectivity with Garmin Wearable devices.
  • General improvement in reliability of phones by fixing top crash issues.

As always, you can check out the official Windows Blog for the full changelog, including a list of known issues!
