Patch Tuesday brings new cumulative updates for Windows 10 PC and Mobile

Microsoft is rolling out a brand new cumulative update for Windows 10 on PC and Mobile today, that brings a bunch of new security updates and under the hood improvements and fixes. These updates are rolling out with Patch Tuesday as build 15063.540 on both PC and Mobile.

Build 15063.540 changelog

  • Addressed issue where the policies provisioned using Mobile Device Management (MDM) should take precedence over policies set by provisioning packages.
  • Addressed issue where the Site to Zone Assignment List group policy (GPO) was not set on machines when it was enabled.
  • Addressed issue where the AppLocker rules wizard crashes when selecting accounts.
  • Addressed issue where the primary computer relationship is not determined when you have a disjoint NetBIOS domain name for your DNS Name. This prevents folder redirection and roaming profiles from successfully blocking your profile or redirects folders to a non-primary computer.
  • Addressed issue where an access violation in the Mobile Device Manager Enterprise feature causes stop errors.
  • Security updates to Microsoft Edge, Microsoft Windows Search Component, Microsoft Scripting Engine, Microsoft Windows PDF Library, Windows Hyper-V, Windows Server, Windows kernel-mode drivers, Windows Subsystem for Linux, Windows shell, Common Log File System Driver, Internet Explorer, and the Microsoft JET Database Engine.

Microsoft provides one known issue for the cumulative update rolling out today: Installing this KB (4034674) may change Czech and Arabic languages to English for Microsoft Edge and other applications.

The update is rolling out to everyone on the stable version of the Windows 10 Creators Update (including Insider Release Preview) right now under the name KB4034674. Users on the Anniversary Update, November Update and original Windows 10 release are also receiving cumulative updates today too.
