Today we are releasing Windows 10 Insider Preview Build 16288 for PC to Windows Insiders in the Fast ring only (not Skip Ahead). As we mentioned previously, we are now at the point of the development cycle for the Windows 10 Fall Creators Update where our focus is now on stabilization for release to the world. This means that we are releasing new builds to Insiders more quickly and that these builds will include mostly bug fixes. You’ll notice that this build continues to include a bunch of good bug fixes Insiders will enjoy.
On Build 16288, you will notice that the watermark at the lower right-hand corner of the desktop has disappeared. You will also see that the OS now reports as “Version 1709” which is the official version number for the Windows 10 Fall Creators Update release. However, this is NOT the final build as we’re not done yet. We’re just now beginning the phase of checking in final code to prepare for the final release. So we will have more builds to release to Windows Insiders between now and then. And the desktop watermark may re-appear in these builds.
We are also releasing Windows 10 Mobile Insider Preview Build 15250 to Insiders in the Fast ring.

- If you’ve encountered an issue where Spotlight appears stuck on a particular image, we’ve added logic such that it should now reset after at most 7 days.
What’s new in Build 15250 for Mobile
Two factor Authentication: We are excited to announce that we’ve introduced a two factor authentication unlock mechanism for Windows 10 Mobile. With two factor unlock, an enterprise can enforce an additional security layer to their sensitive data via an MDM policy. Once two factor unlock is enabled, a phone user will have to enter a numeric pin followed by an enterprise-defined factor to unlock the phone. An example of an enterprise-defined factor is a companion device such as an NFC tag which can be used to unlock a phone using our Companion Device Framework sample app and documentation.
AppLocker Improvements: A number of customers have provided feedback on the warning prompts for apps that are blocked by enterprise policies. We’ve improved the UX and updated the MDM SyncML scripts associated with the policies. Application restrictions can be configured by either the ApplicationManagement CSP or AppLocker CSP.
VPN Improvements: In the modern corporate workplace, mobility is mainstream and secure access to corporate data via VPN has become the norm. We are bringing a range of improvements and features that enhance the reliability of VPN on Windows 10 Mobile. The key updates to our VPN capability are:
- Lots of reliability improvements for VPN connectivity in Windows 10 Mobile.
- IKEv2 Sleep and Power Enhancements.
- VPN completes all pending actions before sleep and disconnects.
- Automatic reconnection on resume.
- Force tunneled improvements for UWP platform.
- Proxy improvements for UWP VPN profile.
- Enabling MMS usage when VPN is connected.
General changes, improvements, and fixes for Mobile
- We fixed a regression that was introduced in build 15245 where the fingerprint reader on the HP Elite X3 did not turn on the screen. You needed to turn on the screen before you could use Windows Hello.
- We fixed some issues where the Maps app navigation would start navigating a route and after performing a reroute, would present a list of possible routes instead of adjusting to the current route.
- We also improved map-matching particularly for routes using ferries.
- We fixed an issue where an app using the routing engine (e.g. Maps) would timeout on providing the route if suspended for more than 30 seconds.
- We fixed an issue where tiles on the Start screen would occasionally be blank.
- We fixed an issue where a VPN profile that was created via the VPN Management API would always be a dial-up profile.
- We fixed an issue with the MDM policy used to control Build Flighting by Mobile Enterprise.
- We fixed a couple of navigation issues when changing from highway to highway (occasionally, signposts were copied from the original highway to the destination highway) and highway to non-highway (erroneous instruction to “enter highway”).
- We fixed a rare issue where the user’s call history was shown as corrupt after an upgrade.
