Symptom & Impact

ConfigMgr deployments miss deadline and patches remain required due to disabled Windows Update service.

Environment & Reproduction

Often introduced by hardening scripts that disable wuauserv.

Get-Service wuauserv
sc qc wuauserv

Root Cause Analysis

Software update scan and enforcement rely on WUA components even under SCCM control.

Quick Triage

Validate client health, policy retrieval, and update scan trigger status.

Get-Service ccmexec,wuauserv
Invoke-WmiMethod -Namespace rootccm -Class SMS_Client -Name TriggerSchedule '{00000000-0000-0000-0000-000000000113}'

Step-by-Step Diagnosis

Solution — Alternative Approaches

Re-install ConfigMgr client repair package if service dependencies are heavily drifted.

Verification & Acceptance Criteria
