Windows 10 PC build 16199 and Mobile build 15215 now available for Insiders

Another week, another Insider Preview build is now rolling out for Insiders in the Fast ring for PC and Mobile! Today's builds are 16199 for PC, and 15215 for Mobile. Mobile includes more fixes and no new features, where the PC build includes some more noteworthy additions over the last build.

What's new and improved for PC?

• Emotive Experience in My People: The next wave of cool features for My People is now available for Windows Insiders! In addition to being able to place your favorite people to the taskbar, today's build brings even more personal ways to stay in touch and share with the people closest to you.
• Notification Badging: The contacts pinned to your taskbar will now display a counter if there are unseen messages, ensuring you have at-a-glance access to communications you have missed from your pinned contacts. Note: You might need to update Skype to version 11.16.556.0 to see notification badges when new Skype messages come in.

• People-first Sharing: You now have two easy ways to share with your people in Windows 10! Drag-and-drop files directly onto the contacts in your taskbar to start an email, or share directly to your contacts via the share picker by choosing from a list recommended people to email.
• Improved Game Settings: We've made some improvements and adjustments that PC gamers will enjoy via Settings > Gaming and the Windows Game bar (WIN + G).
• Other Settings Updates: One of our ongoing goals is to help make it easier for you to understand the state of your system and quickly get to the settings you need to tailor your Windows 10 experience. With that, this build brings two new features to Settings:
• Settings > System > About now integrated with System Health: The About Settings page has been simplified to be accessible to all customers. In addition to the overall UX cleanup, we have also added a health section that pulls in information from the Windows Defender Security Center so you can see your system health at a glance.
• Tips and Videos in Settings: To help you learn more about your options, we're starting to add tips and videos to Settings. We're still growing our collection, but to start with you can find them in under Settings > Ease of Access or Settings > Update & security, a handful of other areas. More content is being added all the time and we're really hoping to get your help figuring out the best tip content for each page. If you have an idea of a tip that would help your least techie friend or family member, please provide us feedback through the feedback hub! Note: Depending on the size of the Settings window, you will find the tips either at the bottom of the page, or on the side.
• Expanding Storage Sense's abilities: During development of the Windows 10 Creators Update, we added the ability to automatically free up space using Storage Sense. We're continuing to grow this feature, and you can now choose to automatically clean up files that have been unchanged in your Downloads folder for 30 days. Just go to Settings > System > Storage and click on "Change how we free up space" to adjust this setting. -Streamlining Narrator Feedback: We've updated Narrator so that when you press Caps Lock + E + E while Narrator is running, it will now launch the Feedback Hub.
• Incoming call notifications: For our Insiders with Android phones, Cortana can now display cross device incoming call notifications! Install the Cortana app on your phone, go to "Settings" > "Sync notifications" and turn on all the Cortana cross-device features. The next time you receive a call, a notification will appear on your Fast ring PC telling you who it is and giving you the option to text back a reply or decline the call.

What's improved for Mobile?

• We fixed an issue where the Call audio did not move to speaker after removing the headset on some phones.
• We have improved power and performance for apps, such as Fitbit, for pair, connect, sync and notifications.
• We fixed an issue where notifications would not be mirrored to the user's PC and Cortana's cross-device settings would not persist.
