Hello Windows Insiders, today we’re releasing 20H2 Build 19042.804 (KB4601319) to anyone running the Windows 10 October 2020 Update. This includes Windows Insiders in the Beta and Release Preview Channels who are on 20H2. This security update includes quality improvements. Key changes include:
- We fixed a possible elevation of privilege vulnerability in the win32k component.
- We fixed an issue that might damage the file system of some devices and prevent them from starting up after running chkdsk /f.
- We fixed a security vulnerability by preventing applications that run as a SYSTEM account from printing to "FILE:" ports. To address this issue in the future, make sure your applications or services run as a specific user or service account.
- Security updates to the Windows App Platform and Frameworks, Windows Apps, Windows Input and Composition, Windows Cloud Infrastructure, Windows Management, Windows Authentication, Windows Fundamentals, Windows Cryptography, Windows Virtualization, Windows Core Networking, and Windows Hybrid Cloud Networking.
