February Patch Tuesday update brings a long list of fixes for the Windows 10 Fall Creators Update

Today is the second Tuesday of February, which means that Microsoft has released new “Patch Tuesday” updates for all shipping versions of Windows 10. For the Fall Creators Update, this month’s Patch Tuesday update is the build 16299.248, which should appear as “KB4074588” in Windows Update.

This latest cumulative update brings a pretty long list of quality improvements, including fixes for issues with Bluetooth keyboards, surround audio, as well as frame rate drops in DirectX games. There are also some unspecified security updates for Microsoft Edge, Windows Kernel, Windows Authentication and more. You can read the full changelog below:

  • Addresses issue where child accounts are able to access InPrivate mode on ARM devices even though their browsing and search history is sent to their parents. This occurs only on Microsoft accounts belonging to children that are managed using the Microsoft Family service and for which parents have enabled activity reporting. This applies to Microsoft Edge and Internet Explorer.
  • Addresses issue with docking and undocking Internet Explorer windows.
  • Addresses issue in Internet Explorer where pressing the delete key inserted a new line in input boxes in an application.
  • Addresses issue in Internet Explorer where selected elements wouldn’t update under certain circumstances.
  • Addresses issue where some users may have experienced issues logging into some websites when using third-party account credentials in Microsoft Edge.
  • Updates time zone information.
  • Addresses issue with browser Compatibility View settings that occurs during updates.
  • Addresses issue where, in certain hardware configurations, the frame rates of DirectX Games were unintentionally limited to a factor of the display’s vertical synchronization.
  • Addresses issue that causes delays when switching keyboard languages using Alt+Shift.
  • Addresses issue where surround sound audio endpoints reverted to stereo after restarting.
  • Improves and reduces conditions where certain Bluetooth keyboards drop keys during reconnection scenarios.
  • Corrects mouse delays for devices that incorrectly report the battery level status.
  • Addresses issue where MMC application snap-ins—such as Services, Local Policy Admin, and Printer Management—fail to run when Windows Defender Application Control (Device Guard) is turned on. The error is “Object doesn’t support this property or method”.
  • Prevents use of the Pre-production Onesettings endpoint for Windows Setup when test signing is enabled.
  • Addresses issue where installations of Windows Server, version 1709 are not automatically activated using the Automated Virtual Machine Activation (AVMA) feature on Hyper-V hosts that have been activated.
  • Addresses issue with the Auto-register Inbox templates feature for UEV where the Scheduled Task didn’t have the proper trigger.
  • Addresses issue where the App-V client didn’t read the policy for SyncOnBatteriesEnabled when the policy was set using a Group Policy Object (GPO).
  • Addresses issue where the Supported On field for the Enable App-V Client policy is blank in the Group Policy editor.
  • Addresses issue where the user’s hive data in the registry is not maintained correctly when some App-V packages belong to the connection group.
  • Provides additional logging for administrators to take action, such as picking a proper configuration for their App-V package, when there are multiple configuration files for a single package.
  • Addresses issue with App-V packages that aren’t compatible with registry virtualization using kernel containers. To address the issue, we changed the registry virtualization to use the earlier (non-container) method by default. Customers who would like to use the new (kernel container) method for registry virtualization can still switch to it by setting the following registry value to 1:
    • Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppV\Client\Compatibility
    • Setting: ContainerRegistryEnabled
    • DataType: DWORD
  • Security updates to Microsoft Scripting Engine, Microsoft Edge, Internet Explorer, Microsoft Windows Search component, Windows Kernel, Windows Authentication, Device Guard, Common Log File System driver, and the Windows storage and file systems.

As Microsoft previously explained, you may not be able to download this update if your AV software hasn’t been updated with a specific registry key, making it compatible with all future Windows 10 updates. As usual, let us know in the comments if you encounter any issues after installing this new build.
