Microsoft just released new Insider builds to both PC and Mobile. PC users received Windows 10 Preview build 16288, while Mobile Insiders got build 15250. Both builds are available to Insiders on the Fast Ring only.

What’s new for PC

The main highlight of Windows 10 Preview build 16288 is that Microsoft finally removed the watermark from Desktop. Additionally, this is the first build that shows version number 1709, which is the official version number for the Windows 10 Fall Creators Update.

Feature-wise, this build brings absolutely no new features. That’s not a surprise, because the official Fall Creators Update is near, and the development team is mainly focused on improving the system and dealing with bugs and issues. Speaking of bugs

Speaking of bugs and issues, build 16288 indeed brings a ton of bug fixes. Most notably, it deals with some of the known issues with Cortana, and other apps. You can check the complete changelog on Microsoft’s official build announcement blog post.

What’s new for Mobile

As for Windows 10 Mobile, build 15250 actually brings one new feature to the system. That feature is (finally) the two-factor authentication. The two-factor authentication will mostly help businesses to protect their sensitive data, by adding an extra layer of security.

“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. “

Besides the two-factor authentication, the new build also brings some AppLocker and VPN improvements. Once again, you can check the complete list of improvements and bug fixes on Microsoft’s official blog post.

To obtain the new build(s), simply check for Windows updates on your device. Remember, you must be on the Fast ring.
