Datto RMM Missing Patches? Why Devices Still Show Missing Updates
Troubleshoot Datto RMM devices that still show missing patches by checking no-data states, policy inheritance, reboot state, and endpoint Windows evidence.
Troubleshooting for MSPs and IT admins troubleshooting missing patch visibility in Datto RMM

If you want to validate Datto RMM patch risk across devices instead of relying on stale patch status alone, run the free audit against your Datto RMM environment.
Quick Answer
Direct answer: when Datto RMM still shows missing patches, the usual causes are stale or missing patch data, reboot debt, or a current-state mismatch between Datto and the endpoint.
Datto RMM missing patches usually means the endpoint has stale or missing patch data, the device still needs reboot, or the current policy and endpoint state are out of sync.
The first split is whether you have a real missing update or just a visibility problem.
What You'll Get
- Separate Datto visibility issues from real missing updates
- Check policy inheritance and endpoint proof before changing approvals
Why Datto RMM Still Shows Missing Patches
Datto missing-patch cases often start as no-data or stale-data problems. The platform may be missing current endpoint evidence, or the device may still be waiting on reboot and final rescan.
How to Check Whether the Device Still Needs the Patch
- Check whether the device has current patch data.
- Check reboot state.
- Check policy inheritance.
- Check endpoint update history.
- Compare Datto output with Windows evidence.
Use verification, event IDs, and logs.
Why Datto RMM Can Mark a Patched Device as Missing
- No current patch data: visibility is stale, not always failed.
- Installed but still unhealthy: reboot completion is missing.
- Expected KB changed: the applicable update set moved.
How to Confirm Patch Status Outside Datto RMM
Use the endpoint directly. This is also why patch compliance vs patch status matters.
What Usually Clears the Missing-Patch State
- Refresh patch data.
- Clear reboot debt.
- Validate policy inheritance and current applicability.
- Compare Datto output with endpoint proof.
- If Windows still truly needs the update, move into the install branch.
When Missing in Datto RMM Does Not Mean Broken Patching
If Datto is only behind the endpoint or missing current patch data, patching may not be broken. Continue to RMM patch report wrong or Datto RMM patching not working.
