Microsoft have released an update to the 20H2 Build of Windows 10. KB4598242 takes the build to 19042.746 and is available for Windows Insiders on the beta and release preview channels. The update contains security updates:
This security update includes quality improvements. Key changes include:
We fixed a security vulnerability issue with HTTPS-based intranet servers. 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.
Security updates to Windows App Platform and Frameworks, Windows Media, Windows Fundamentals, Windows Cryptography, Windows Virtualization, Windows Peripherals, and Windows Hybrid Storage Services.
