Microsoft rolled out a new build of Windows 10 to Insiders in the Beta and Release Preview Channels yesterday. The update brings PCs to build 19042.804. The build doesn't include any new features but does include several bug and security fixes.
Here are the key changes, as outlined in a blog post from Microsoft:
- 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.
You can read more about the build, including known issues and workarounds, on a Microsoft support page (opens in new tab).
Microsoft also has more details about the security updates and fixes that you can find in its Security Update Guide (opens in new tab).
The new build will roll out to Insiders running the Windows 10 October 2020 Update, which includes Insiders in the Beta and Release Preview Channels who are on 20H2.

Is there any word on 21h1?
After installing the update, my Surface Book 2 is moving like tar. Had anyone experienced this issue?
Afraid not. Could just be a refresh of system files corrupted by other things
Tried that several times. I had to remove it completely for normal operation. Came back to seeing it back on the laptop after it restarted and it's the same issue.
