Microsoft released an emergency update (KB5063159) to address startup failures in certain Surface Hub v1 devices running Windows 10, specifically those encountering Secure Boot Violation errors after installing the June 2025 Windows security update (KB5060533). The issue was limited to Surface Hub v1 systems on Windows 10, version 22H2, and did not affect Surface Hub 2S and 3 devices. Microsoft paused the rollout of the KB5060533 update on June 11, 2025, to prevent further complications. Additionally, the June 2025 Patch Tuesday updates included security patches for 66 vulnerabilities, including critical ones that allowed remote code execution and privilege escalation.
