Microsoft Releases Update KB4051963 for Windows 10 Fall Creators Update


Microsoft today released cumulative update KB4051963 for Windows 10 Fall Creators Update version 1709 which is the second patch this week.

Microsoft today released a new cumulative update for Windows 10 Fall Creators Update version 1709. This new update, KB4051963, comes following the release of KB4048955 which was released earlier this month as part of Patch Tuesday.

Windows 10 Cumulative Update KB4051963

The update doesn’t include any new features but does include several bug fixes and improvements. Here is a list of what is improved in this update:

  • Addressed a script-related issue that caused Internet Explorer to stop working in some cases.
  • Addressed issue with the Input Method Editor’s (IME) text input window for Internet Explorer.
  • Addressed issue with rendering a graphics element in Internet Explorer.
  • Addressed issue with form submissions in Internet Explorer.
  • Addressed issue where the Location-hash is lost when navigating back if you previously navigated to an invalid URL.
  • Addressed issue where applications may stop responding for customers who have internet or web proxies enabled using PAC script configurations. This is a result of a reentrancy deadlock in WinHTTP.dll. This can result in the following:
  • Microsoft Outlook cannot connect to Microsoft Office365.
  • Internet Explorer and Microsoft Edge cannot successfully render any content (including local computer content, local network content, or web content).
  • Cisco Jabber stops responding, which blocks messaging and telephony features.
  • Any application or service that relies on WinHTTP is impacted.
  • Addressed a performance regression when users run full-screen Microsoft DirectX 9 games and applications.
  • Addressed issue that prevents Forza Motorsport 7 and Forza Horizon 3 from running on some high-end gaming laptop configurations.
  • Addressed issue where user selections for Feedback Frequency in Settings > Privacy > Feedback & diagnostics aren’t saved.
  • Addressed issue where RNDIS5 networking devices don’t get a valid IP address or don’t show network connectivity. If the issue continues after installing the update, you may need to uninstall and reinstall your Remote NDIS network adapter using Device Manager.
  • Addressed issue where if a user manually changes the system’s time zone and doesn’t log off or restart, the new time doesn’t display on the Lockscreen clock.
  • Addressed issue that impacted some Epson SIDM (Dot Matrix) and TM (POS) printers, which were failing to print on x86 and x64-based systems. This issue affects KB4048955.

You should get the update automatically, but if you want to stay on top of things head to Settings > Update & security > Windows Update. After you the updates are downloaded, a restart is required to finish the update process. Or, you can download the standalone package and manually install it.

    The download and configuration went fine; thought it had fully installed until I got a “failure to install” message with error 0x80070643.

      I also got the failure message with error 0x80070643. I called Microsoft. One of the technicians took control of my Windows 10 Professional machine, checked for installed updates and found that KB 4051963 IS actually installed (found under “Installed updates”) and that I am up to build number 16299.98. When checking for more updates, I’m prompted that updates are up to date. Microsoft will call me about an explanation tomorrow after an advanced technician has looked into why the update installed but is listed as “failed to install” under Update History.

      Microsoft called me back today and assured me that as long as update KB4051963 is listed as installed under temporary update files, I will be updated. The temporary update files can be found as follows: C:\Windows\SoftwareDistribution\Download. (Make sure “Hidden” items” is checked under View in Explorer). In my case, the update is listed as installed in spite of it showing as “failed” in Update History.

        What we expects to find in this download folder? the standalone downloaded file so we can use again?

          To be assured that update KB4051963 was installed, click START > “Settings” > “Update & Security”, “View installed update history”, “Uninstall updates”. There, you will find all the installed updates, and KB4051963 should be one of them, if the installation went through. Another way to get to “Installed Updates” is to go to “Control Panel” > Programs > Programs and Features > Installed Updates (on left).

    Installing now and the machine is running fine.

    But, I have to say, I’m only into the 13th hour downloading and installing this behemoth – “Preparing to install updates 66%” Seriously – there’s got to be some better way than 10 hours of bandwidth hogging and another 3 (so far) of a slow as cold molasses “preparing to install.” I can hardly wait for the tri – cycle of reboots, watching a lazy spinner, and cautions to not turn off my computer. I could protest how powerful this machine is but what would be the point? This process has pretty much halted all work I have going on this machine and I don’t like it.

    This update caused my PlayOn application to stop working. Can’t find a way to stop the update and now one of my most used apps is hosed. I may have to finally move to Linux if I want to have a PC of my own again. I am tired having a machine I built myself that is now owned by Microsoft.

      Thnx for the update Doug. Glad to hear there was no issue. Sometimes we only get the comments about the issues so it’s good to see the other side of it as well. ;)

    My computer crashed after the update. Windows 10 repair failed at repairing. Only way to fix it was to restore to factory settings.

    Download/assembly/updating went fine however also failed with error 0x80070643 on my Windows 10 Home install — but it is listed in installed updates able to be uninstalled.

    Housemate’s PC running Windows 10 Pro installed successfully with no errors.

    Previously posted I had no issues. Elliott mentioned he had success with Windows 10 Pro. Which I use on 2 Pc’s. Are others only having errors with the home editon?

      I got the error message on a Windows 10 Pro machine, while the other computer, Windows 10 Home Edition, installed without a glitch. As I mentioned, although the update is listed under “Update History” as failed, it is listed as installed in the Control Panel under “Installed Updates”. Make sure to check for that.

    “View installed update history” reports “Failed to install on ‎05/‎12/‎2017 – 0x80070643″, but OS Build version is nevertheless shown as 16299.98. Update took about 15 minutes to download and install on PC running Windows 10 Home.
