/diagnose

Runs Windows Update health checks from interactive mode.

Synopsis

/diagnose --fix [--force|-f]

Options

Option	Detail
--refresh	Force fresh scan during diagnosis.
--json	Print structured diagnostic report.
--fix	Reset Windows Update components. Requires Administrator.
--force, -f	Skip --fix confirmation prompt.

Behavior

/diagnose health check is read-only unless --fix is used.

/diagnose --fix is destructive: stops WU services, renames WU stores, resets network/proxy pieces, restarts services, then requests a new WUA scan.
