Syncro Not Detecting Patches: Check Scans and Update Scope
Troubleshoot Syncro not detecting patches. Check collection freshness, update scope and endpoint availability.
Quick Answer
Check the update type first. The Windows Updates module handles its supported OS updates; feature upgrades use separate community-library scripts. For an expected OS patch, compare the latest asset scan with Windows availability.

What You'll Get
- Find where scanning, approval or installation stopped
- 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
- Classify the expected update as OS quality, feature upgrade or another product.
- Check the Windows Updates module’s documented scope.
- For an in-scope KB, compare refreshed asset inventory with endpoint availability.
Interpret the Result
| Evidence | Next action |
|---|---|
| No completed inventory returned | Investigate collection and communication; patch state is still unknown. |
| Current inventory has no applicable candidate | Check update type and OS applicability before diagnosing scan failure. |
| Windows offers the update but fresh managed inventory omits it | Escalate with matching device/update identities and both scan results. |
Validate the Outcome
Check one affected device and an update it should receive. Save the scan time and returned update list. If the scan fails, repair collection before deciding whether the device is up to date.
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.
