Improvements and fixes:

  • Addresses additional issues with updated time zone information.
  • Addresses an issue that may cause the operating system to stop responding when transitioning from Sleep to Hibernation.
  • Addresses an issue that can cause App-V packages to fail because of a missing file or DLL error.
  • 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 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 with cloud authentication performance for accounts that create logon sessions very quickly.
  • 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 applications on systems with more than 4 GB of memory receive Access Denied error code “0x5” when calling CreateProcessWithLogonW().
  • 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 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.
  • 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.
