Windows Update settings on Windows 10

Microsoft begins to roll out KB3176931 for Windows 10 build 14393 only hours after the release of update KB3176495. However, the difference is that KB3176931 is only available for PC and Mobile devices enrolled in the Slow, Fast, or Release Preview ring. 

The new update bumps the build number from 14393.51 to 14393.67, and it includes all the same fixes found in KB317649, but with two additional fixes:

  • Fixed issue that causes significantly reduced battery life on Windows Phone when using Bluetooth with “Hey Cortana” feature enabled.
  • Fixed problem that prevents users from completing the out-of-box experience (OOBE) with a local account using Korean characters.

Windows 10 build 14393.67 (KB3176931) for PC and Mobile is available immediately. The new update will download and install automatically, but you can always force the update from Settings > Update & security > Windows Update and clicking the Check for updates button.
