Resolution playbook

From symptom to verified fix

Start with evidence, change one variable at a time, and confirm the result before closing the incident.

Likely causes

The device may be on this exact historical build.
A servicing or compliance report may be showing an older inventory snapshot.
Edition, channel, enablement package, and installed cumulative update determine the effective version.

Recommended fix

Compare the device's current OS build with this record.
Open the linked Microsoft update record and review prerequisites, known issues, and supersedence.
If the device should be newer, inspect update policy, safeguard holds, servicing health, and the latest scan result.

Verify

Confirm the current build again after a reboot and update scan.
Verify the expected KB appears in update history or installed hotfix inventory.
Confirm the management platform reports a fresh check-in after the update.

Escalate when

The device cannot move beyond this build after prerequisites and policy are confirmed.
The update fails repeatedly with a specific HRESULT or rollback event.
You have the device edition, architecture, current build, target KB, WindowsUpdate logs, and UTC failure time.
