Frequently Asked Questions

Does this mean something is fundamentally wrong with my Windows installation?
Not necessarily — it's often a more transient issue related to the update client itself getting into a confused state, which resetting the Windows Update components typically resolves.
Will a Windows Update troubleshooter fix this automatically?
It's worth trying first, since the built-in troubleshooter can automatically detect and fix a meaningful share of these more generic update-client issues.
