New build shipped to Beta and Release Preview channels

Microsoft has just shipped a new build to Windows insiders in the Beta and Release Preview channels, this time with the purpose of fixing security vulnerabilities in Windows 10 version 20H2.

Since it’s Patch Tuesday, Windows 10 build 19042.746 lands as cumulative update KB4598242, and the focus is entirely on fixing security bugs. In other words, you’re not getting any new features as part of this release, and Microsoft says it corrected an important security vulnerability affecting HTTPS-based intranet servers.

The company explains the following in the changelog published today:

“After installing this update, HTTPS-based intranet servers cannot, by default, use a user proxy to detect updates. Scans using these servers will fail if you have not configured a system proxy on the clients. If you must use a user proxy, you must configure the behavior using the policy “Allow user proxy to be used as a fallback if detection using system proxy fails.” To ensure the highest levels of security, also use Windows Server Update Services (WSUS) Transport Layer Security (TLS) certificate pinning on all devices. This change does not affect customers who are using HTTP WSUS servers.”

More security improvements

And because this new release update happens on a Patch Tuesday, there are the typical security improvements for Windows 10 and the built-in components, including Windows App Platform and Frameworks, Windows Media, Windows Fundamentals, Windows Cryptography, Windows Virtualization, Windows Peripherals, and Windows Hybrid Storage Services.

Windows 10 version 20H2 is the latest feature update released by Microsoft, and it lands in the form of a smaller pack of improvements. The focus was on under the hood improvements and not necessarily on new features, and the rollout is currently under way to devices across the world.

The next feature update for Windows 10 is projected to go live in the spring of this year.
