Syncro Missing Patches: Verify Inventory and Applicability
Investigate Syncro missing patches. Compare current inventory, update applicability and installed evidence before changing policy.
Quick Answer
Syncro Missing Patches includes updates whose approval is Defer or Manual. Failed Patches is a separate group. Check where the KB appears before treating a deferred missing update as a failed installation.

- Check the result and collect useful details for support
How Patching Works
Syncro uses Windows Updates policies for approvals and schedules, with results in the Windows Patches asset view. Feature upgrades use separate scripts, and third-party application updates have their own policy module.
Checks to Run in Order
- Separate Missing Patches from Failed Patches and Rejected Patches.
- Check whether the effective approval is Manual or Defer.
- After an authorized install/restart, verify installed evidence and a refreshed list.
Interpret the Result
| Evidence | Next action |
|---|---|
| Current scan offers the update | Inspect approval and the last eligible installation; the backlog may be real. |
| Installed evidence and a later scan agree | Keep update/build identity with the explanation for the older report. |
| Expected KB is no longer applicable | Verify the replacement target against Microsoft release information before closing the gap. |
Validate the Outcome
After a fresh scan, check whether the update is still needed, installed or replaced by a newer update. Save the update and device details, and keep any outstanding security updates on your follow-up list.
Prepare a Useful Escalation
Send the device ID, Windows edition and build, update KB or title, patch policy, scan time, installation time and exact error. Include the time zone, relevant logs and what changed after your test.
Use the Windows Update logs guide to find the logs for the failed scan, download, installation or restart.
