As a part of this month’s Patch Tuesday, Microsoft released yet another cumulative update for Windows 10. The update, dubbed as KB3189866, is available to all users running Windows 10 version 1607 (the Anniversary Update). Once you install this update, the system version is going to be changed to 14393.187.

Just like every previously released cumulative update for Windows 10, KB3189866 also brings no new features, but instead focuses on “quality improvements and security fixes”. The update includes a handful of minor tweaks for Microsoft Edge, Internet Explorer 11, Windows Shell, and more.

Here’s the complete changelog of the update:

  • “Improved reliability of Windows Shell, map apps, Internet Explorer 11, and Microsoft Edge.

  • Addressed issue causing push-button reset to not work correctly and roll back on devices with language set to any of the Unicode languages.

  • Addressed issue causing devices to crash after disconnecting an e-reader that was attached to the device. 

  • Addressed issue causing devices to not recognize a Secure Digital (SD) card if it is inserted and removed multiple times.

  • Addressed issue causing some apps to not respond to the commands in the app bar in Windows 10 Mobile.

  • Addressed issue that sometimes blocks alarm notifications in Windows 10 Mobile.

  • Improved support for using the camera app in Windows 10 Mobile Enterprise.

  • Addressed additional issues with rendering 4K resolution, missing Start menu tiles when running on battery, Internet Explorer 11, Microsoft Edge, Bluetooth compatibility, graphics, display rotation, app compatibility, Wi-Fi, Feedback Hub, Miracast, Windows Shell, revised daylight saving time, and USB.

  • Security updates to Microsoft Edge, Internet Explorer 11, Microsoft Graphics Component, Windows kernel, and Adobe Flash Player.”

You should have already received the update by now, so just head to the Settings app > Updates & security, and install it.

As usual, Microsoft also released two more updates, for two previous versions of Windows 10 (1507 and 1511), just like it does during every Patch Tuesday. Users of Windows 10 version 1507 (initial July 2015 release) got cumulative update KB3185611, while users of Windows 10 version 1511 (Threshold 2) got KB3185614. To find more details about each update, check out Microsoft’s Update History page.
