September Patch Tuesday is here and it comes with a lot of improvements.

Windows 10 v1903 gets improved network technologies

Windows 10 v1903 Build 18362.356 (KB4515384) gets some updates to improve security when using Internet Explorer and Microsoft Edge.

Also, there are a series of improvements to network technologies and input devices such as a mouse, keyboard, or stylus.

There are also some updates for storing and managing files and verifying user names and passwords.

Here’s the full list of improvements and fixes:

  • Provides protections against a new subclass of speculative execution side-channel vulnerabilities, known as Microarchitectural Data Sampling, for 32-Bit (x86) versions of Windows (CVE-2019-11091, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130).

  • Security updates to Microsoft Edge, Internet Explorer, Microsoft Scripting Engine, Windows App Platform and Frameworks, Windows Input and Composition, Windows Media, Windows Fundamentals, Windows Authentication, Windows Cryptography, Windows Datacenter Networking, Windows Storage and Filesystems, Windows Wireless Networking, the Microsoft JET Database Engine, Windows Kernel, Windows Virtualization, and Windows Server.
