The October 2019 Patch Tuesday is finally here with an assortment of new features.

It seems that with KB4519338 Microsoft focused on improving security when using Internet Explorer and Microsoft Edge, as well as some improvements with username and password recognition.

Additionally, the major update also contains changes for Microsoft HoloLens (OS Build 17763.806) released October 8, 2019.

KB4519338 still has a lot of unresolved issues

Check out the full list of quality improvements and changes:

  • Addresses an issue in the Keyboard Lockdown Subsystem that may not filter key input correctly.
  • Addresses an issue in security bulletin CVE-2019-1318 that may cause client or server computers that don’t support Extended Master Secret (EMS) RFC 7627 to have increased connection latency and CPU utilization. This issue occurs while performing full Transport Layer Security (TLS) handshakes from devices that don’t support EMS, especially on servers. EMS support has been available for all the supported versions of Windows since calendar year 2015 and is being incrementally enforced by the installation of the October 8, 2019 and later monthly updates.
  • Addresses an issue with applications and printer drivers that utilize the Windows JavaScript engine (jscript.dll) for processing print jobs.
  • Security updates to Windows Shell, Internet Explorer, Microsoft Scripting Engine, Microsoft Edge, Windows App Platform and Frameworks, Windows Cryptography, Windows Authentication, Windows Kernel, and Windows Server.

Unfortunately, some users should be aware that it also comes with a few issues.

For example, devices with some Asian language packs installed may receive the error, “0x800f0982 -PSFX_E_MATCHING_COMPONENT_NOT_FOUND.”
