Microsoft Windows 10 ESU enrollment failure and KB5071959 fix
Service Disruption
Summary

Show ▼
Microsoft had to ship KB5071959 after the Windows 10 Consumer ESU enrollment process failed for some users. The disruption prevented affected devices from completing enrollment in the legacy security-update program. Restoring the wizard matters because ESU is the last patch path for Windows 10 systems that still need coverage.
