Windows 10 1511 Updated to Build 10586.122

In the second monthly update to Windows 10 1511 since Microsoft adopted a more transparent communication stance with customers, the software giant is delivering improved reliability and performance, and numerous other fixes.

You can read more about Microsoft’s new level of disclosure for Windows 10 updates in Microsoft Finally Offers Windows 10 Update Information. But to clear, this is not a new “build” of Windows 10 per se, and is not a new pre-release Windows Insider build of some future Windows 10 release. It is instead a cumulative update for the current, shipping version of Windows 10, which is called 1511. So this is something that non-Insiders will see on their production Windows 10 PCs.

Put another way, the cumulative update KB3140743 updates the public, shipping version of Windows 10 to version 10586.122.

Key changes include:

  • Improved reliability in numerous areas, including OS and Windows Update installation, startup, installing and configuring Windows for the first time, authentication, resuming from hibernation, shutdown, kernel, Start menu, storage, Windows Hello, display modes, Miracast, AppLocker, Internet Explorer 11, Microsoft Edge browser, network connectivity and discovery, and File Explorer.
  • Improved performance in video thumbnail generation, NetLogon, Windows Store, and standby power consumption.
  • Improved support for devices including some wearables, displays, and printer scenarios.
  • Reset app defaults when a registry setting is deleted or corrupted and streamlined notification about the corruption.
  • Fixed an issue causing favorites to be lost after updates are installed.
  • Fixed several issues that individually could cause certain apps to fail to launch, update, or allow in-app purchases.
  • Improved quality of Cortana voices and translations of multiple languages of an Internet Explorer dialog box.
  • Improved support for apps, fonts, graphics and display, airplane mode, Group Policy, PowerShell MDM, Windows Journal, Microsoft Edge, printing, touch display, roaming credentials, Push-Button Reset, Windows UX, local and streaming video, audio quality, error reporting, USMT, and VHD creation.

So there are no new “features” here per se, though of course it’s important to remember that the biggest Windows 10 updates we see month to month typically come in the form of app updates.

You can find this update in Windows Update.
