Applies to: Windows 10, version 1709

Improvements and fixes


This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:

  • Addresses the redenomination of local currency that the Central Bank of Venezuela implemented to enter the Bolivar Soberano into circulation. 
  • Addresses an issue in which searching using Microsoft Outlook’s Social Connector returns nothing, which causes the People's pane results to always be empty. 
  • Addresses additional issues with updated time zone information. 
  • Addresses an issue that prevents the clock and date flyout from appearing when the region format is Spanish (Spain) and the sorting method is Traditional. 
  • Addresses an issue with navigation from the Decade view in the Japanese calendar. When the user tries to go from the Current era to the next era, navigation does not work properly. 
  • Addresses an issue to support Microsoft Office events in the “Limit Enhanced” Group Policy setting list. 
  • Addresses an issue in which applications on systems with more than 4 GB of memory receive Access Denied error code “0x5” when calling CreateProcessWithLogonW()
  • Addresses an issue that makes it impossible to disable TLS 1.0 and TLS 1.1 when the Federal Information Processing Standard (FIPS) mode is enabled. 
  • Addresses an issue in which the AccountName in the Event Log entry for the Microsoft-Windows-Kerberos-Key-Distribution-Center source and Event ID 7 sometimes appears corrupted. 
  • Addresses an issue in which applications have handle leaks when using client authentication certificates with the TLS protocol. This issue occurs when the FreeCredentialsHandle call occurs before the DeleteSecurityContext call in application code. 
  • Addresses an issue that might cause TCP connections opened for an application running on Windows Container to fail sporadically. This occurs when the container runs on a Network Address Translation (NAT) Network provided by Windows Network Address Translation (WinNAT). A SYN timeout occurs after reaching the maximum SYN Retransmit count. 
  • Addresses an issue that prevents the deletion of Immediate Tasks when their deletion timer occurs, such as when you configure Group Policy preferences for Immediate Task actions. 
  • Addresses an issue that can cause App-V packages to fail because of a missing file or DLL error. 
  • Addresses an issue that may cause certain applications to stop responding after installation.
  • Addresses an issue that fails to mount a volume when running Mount-SRDestination to bring a destination volume online as part of the Test Failover feature.
  • Addresses an issue in which the System.Security.Cryptography.Algorithms reference was not correctly loaded on .NET Framework 4.7.1 after the July 10, 2018 and August 14, 2018 patches.
  • Addresses an issue that may cause the system to stop working during the shutdown of some Windows Presentation Foundation (WPF) apps because of TaskCanceledException. Apps that are vulnerable to this issue perform work involving weak events or data binding after the Application.Run() function returns values.
  • Addresses a race condition in temporary files and some antivirus scanners that causes .NET Framework applications to stop working. The error message is, "The process cannot access the file <name of temp file>".
  • Updates the .NET Framework's support for the formatting of Japanese dates for the first year in the eras. When the format pattern is “y年”, the year format will use the symbol 元 and not use year number 1. Additionally, the .NET Framework will support dates that include 元.
  • Updates Venezuela currency information. This will affect the culture of “es-VE” as follows:
    • The currency symbol is “Bs.S”.
    • The English currency name is “Bolívar Soberano”.
    • The local currency name is “bolívar soberano”.
    • The International Currency Code is “VES”.
  • Addresses an issue with a dialog box that may appear with a non-applicable message beginning with the words, “Hosted by...” when first starting Microsoft Edge. The dialog box only appears if you have turned on “Block only third-party cookies” in Microsoft Edge and applied certain language packs after installing the October 9, 2018 update.
  • Addresses an issue that may cause an application that has a child window to stop processing mouse inputs. This issue occurs when a precision touchpad triggers a WM_MOUSEWHEEL event.

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.
