Microsoft recently rolled out a new cumulative update for Windows 10 users. Update KB3206309 brings Windows 10 to build version 14986.1001. For the time being, though, there is no official information regarding the content of this update.

Microsoft released KB3206309 for Windows 10 build 14986 which means the update is available only to Windows Insiders. Since this update is now available to Slow Ring Insiders, it’s safe to assume that Microsoft will roll it out to the general public by the end of the year.

Insiders confirm that update KB3206309 revamps Windows Defender. After installing the update, Windows 10 displays a message informing users that Windows Defender is making some improvements. More specifically, the update adds new features to Windows Defender, finishing the antivirus’ new look.

Windows Defender is making some improvements.  We’re working hard on adding new features and finishing our new look, so not everything is ready quite yet.  Some features you’re looking for may not be available now, which is why the previous version of Windows Defender is still available on your device.”

It appears that KB3206309 is mainly a security update.
