February 2018 Patch Tuesday updates for Windows 10 Fall Creators Update now rolling out as KB4074588

Microsoft is now rolling out this months Patch Tuesday updates for Windows 10 PCs. This months Patch Tuesday, much like previous Patch Tuesdays, includes bug fixes and security patches. There are no new features included with this update. The update itself is rolling out as KB4074588 (opens in new tab) on the Fall Creators Update, and bumps the build number to 16299.248. Here's what's changed!


  • 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.
  • 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.

The update is also rolling out on older supported versions of Windows, including Windows 7, Windows 8.x and older versions of Windows 10. You can grab the updates now via Windows Update!

  • "Addresses issue that causes delays when switching keyboard languages using Alt+Shift" Second time in a row! Probably it hadn't been fixed in the previous patch Tuesday. Indeed, it hadn't :P
  • This problem has been bothering me for a while
  • Is it also available for windows 10 mobile?
  • No more updates for W10M are coming 😪
  • Not even security updates?!
  • You are wrong. No more insider updates are coming, but there will be cumulative updates till 2019/2020
  • Stretching it with 2020 :P
  • https://support.microsoft.com/en-us/help/13853/windows-lifecycle-fact-sheet Windows 10, version 1709: End of service April 9, 2019 plus 6 additional months for the Enterprise Edition
  • My Lumia 1520 is downlding the new patch at the moment: 10.0.14393.2068 , so yes W10M updates are still coming, but only security/bug fixes and not new features.
  • Not true. I still get updates on my Lumia 950xl, actually got a Groove Music update a week or so ago. My Lumia 830 still gets app updates also. Heck, my Lumia 630 still gets updates sometimes, that's on wm8.
  • yes but it a slow roll out
    Also my exit insider preview to check there
  • Yupp! My Lumia got an update on w10m non-insiders.
  • Would be nice if they addressed the issue of the English US language being installed automatically after EVERY update.
  • The OS was written in EN-US.
    You must have EN-US installed and then default to your region language. In-fact if your default is English - UK, South Africa, Australia, Canada etc... most of the OS dialog boxes remain US.
  • That's not the case and there is plenty of Feedback on this issue in the Feedback Hub. I specifically stated in setup to install EN-GB as the default and ONLY language on the system and the system just spontaneously installs EN-US with no interaction from me and it DOES NOT show up in Time & Language settings, I have also switched every possible setting to EN-GB and it still does it.
  • Yeah they need to fix the SB2 15" lag. At times, it becomes so friggen slow. Pissed I dropped over $3k on this thing, outside of return period now.
  • If the surface book 2 is not working properly than lodge a complaint, you're well within your rights to do so. Especially on such a high end product.
