About this tag
KB5079473 is a March 2026 cumulative update for Windows 11 versions 24H2 and 25H2, advancing builds to 26100.8037 and 26200.8037. It introduces notable features including Sysmon as an optional in-box capability, a taskbar internet speed test, and Emoji 16 support. The update also improves File Explorer search reliability across multiple drives and This PC. However, KB5079473 has been linked to significant issues, including Microsoft account sign-in failures in apps like OneDrive, Edge, Teams Free, and Microsoft 365 Copilot, often showing a misleading offline error. Microsoft acknowledged the problem and released an out-of-band update, KB5085516, to address it. The update also includes security fixes and enterprise-focused controls such as WDAC and Secure Boot improvements.
