# Collect Update Compliance diagnostic data for Windows Defender AV Assessment
**Applies to:**
- Windows 10
**Audience**
- IT administrators
This topic describes how to collect diagnostic data that can be used by Microsoft support and engineering teams to help troubleshoot issues you may encounter when using the Windows Defender AV Assessment section in the Update Compliance add-in.
Before attempting this process, ensure you have read the [Troubleshoot Windows Defender Antivirus reporting](troubleshoot-reporting.md) topic, met all require pre-requisites, and taken any other suggested troubleshooting steps.
1. On at least two endpoints that are not reporting or showing up in Update Compliance, obtain the .cab diagnostic file by following this process:
1. Open an administrator-level version of the command prompt:
1. Open the **Start** menu.
2. Type **cmd**. Right-click on **Command Prompt** and click **Run as administrator**.
3. Enter administrator credentials or approve the prompt.
2. Navigate to the Windows Defender directory. By default, this is C:\Program Files\Windows Defender, as in the following example:
```Dos
cd c:\program files\windows\defender
```
3. Enter the following command and press **Enter**
```Dos
mpcmdrun -getfiles
```
4. A .cab file will be generated that contains various diagnostic logs. The location of the file will be specified in the output in the command prompt, but by default it will be in C:\ProgramData\Microsoft\Windows Defender\Support\MpSupportFiles.cab.
2. Copy these .cab files to a location that can be accessed by Microsoft support. An example could be a password-protected OneDrive folder that you can share with us.
3. Send an email using the <a href="mailto:ucsupport@microsoft.com?subject=WDAV assessment issue&body=I%20am%20encountering%20the%20following%20issue%20when%20using%20Windows%20Defender%20AV%20in%20Update%20Compliance%3a%20%0d%0aI%20have%20provided%20at%20least%202%20support%20.cab%20files%20at%20the%20following%20location%3a%20%3Caccessible%20share%2c%20including%20access%20details%20such%20as%20password%3E%0d%0aMy%20OMS%20workspace%20ID%20is%3a%20%0d%0aPlease%20contact%20me%20at%3a">Update Compliance support email template</a>, and fill out the template with the following information:

# Troubleshoot Windows Defender Antivirus reporting in Update Compliance
**Applies to:**
- Windows 10
**Audience**
- IT administrators
When you use [Windows Analytics Update Compliance to obtain reporting into the protection status of machines or endpoints](/windows/deployment/update/update-compliance-using#wdav-assessment) in your network that are using Windows Defender Antivirus, you may encounter problems or issues.
Typically, the most common indicators of a problem are:
- You only see a small number or subset of all the devices you were expecting to see
- You do not see any devices at all
- The reports and information you do see is outdated (older than a few days)
For common error codes and event IDs related to the Windows Defender AV service that are not related to Update Compliance, see the [Windows Defender Antivirus events](troubleshoot-windows-defender-antivirus.md) topic.
There are three steps to troubleshooting these problems:
1. Confirm that you have met all pre-requisites
2. Check your connectivity to the Windows Defender cloud-based service
3. Submit support logs
>[!IMPORTANT]
>It typically takes 3 days for devices to start appearing in Update Compliance
## Confirm pre-requisites
In order for devices to properly show up in Update Compliance, you have to meet certain pre-requisites for both the Update Compliance service and for Windows Defender AV protection:
>[!div class="checklist"]
>- Endpoints are using Windows Defender Antivirus as the sole antivirus protection app. [Using any other antivirus app will cause Windows Defender AV to disable itself](windows-defender-antivirus-compatibility.md) and the endpoint will not be reported in Update Compliance.
> - [Cloud-delivered protection is enabled](enable-cloud-protection-windows-defender-antivirus.md).
> - Endpoints can [connect to the Windows Defender AV cloud](configure-network-connections-windows-defender-antivirus.md#validate-connections-between-your-network-and-the-cloud)
> - If the endpoint is running Windows 10 version 1607 or earlier, [Windows 10 telemetry must be set to the Enhanced level](https://docs.microsoft.com/en-us/windows/configuration/configure-windows-telemetry-in-your-organization#enhanced-level).
> - It has been 3 days since all requirements have been met
If the above pre-requisites have all been met, you may need to proceed to the next step to collect diagnostic information and send it to us.

# Windows Defender Antivirus and Advanced Threat Protection: Better together
# Windows Defender Antivirus and third party protection products
**Applies to:**
- Windows 10
- Windows Server 2016
**Audience**
- Enterprise security administrators
Windows Defender Antivirus is automatically enabled and installed on endpoints and devices that are running Windows 10.
Windows Defender Advanced Threat Protection (ATP) is an additional service beyond Windows Defender Antivirus that helps enterprises detect, investigate, and respond to advanced persistent threats on their network.
See the [Windows Defender Advanced Threat Protection](../windows-defender-atp/windows-defender-advanced-threat-protection.md) topics for more information about the service.
However, on endpoints and devices that are protected with a non-Microsoft antivirus or antimalware app, Windows Defender AV will automatically disable itself.
If you are enrolled in Windows Defender ATP, and you are not using Windows Defender AV as your real-time protection service on your endpoints, Windows Defender will automatically enter into a passive mode. On Windows Server 2016 SKUs, Windows Defender AV will not enter into the passive mode and will run alongside your other antivirus product.
If you are also using Windows Defender Advanced Threat Protection, then Windows Defender AV will enter a passive mode.
In passive mode, Windows Defender AV will continue to run (using the *msmpeng.exe* process), and will continue to be updated, however there will be no Windows Defender user interface, scheduled scans won't run, and Windows Defender AV will not provide real-time protection from malware.
On Windows Server 2016, Windows Defender AV will not enter passive or disabled mode if you have also installed a third-party antivirus product. See [Windows Defender Antivirus on Windows Server 2016](windows-defender-antivirus-on-windows-server-2016.md) topic for key differences and management options for Windows Server installations.
You can still [manage updates for Windows Defender](manage-updates-baselines-windows-defender-antivirus.md), however you can't move Windows Defender AV into the normal active mode if your endpoints have an up-to-date third-party product providing real-time protection from malware.
The following matrix illustrates how Windows Defender AV operates when third-party antivirus products or Windows Defender ATP are also used.
If you uninstall the other product, and choose to use Windows Defender AV to provide protection to your endpoints, Windows Defender AV will automatically return to its normal active mode.
Windows version | Antimalware protection offered by | Organization enrolled in Windows Defender ATP | Windows Defender AV state
-|-|-|-
Windows 10 | A third-party product that is not offered or developed by Microsoft | Yes | Passive mode
Windows 10 | A third-party product that is not offered or developed by Microsoft | No | Automatic disabled mode
Windows 10 | Windows Defender AV | Yes | Active mode
Windows 10 | Windows Defender AV | No | Active mode
Windows Server 2016 | A third-party product that is not offered or developed by Microsoft | Yes | Active mode
Windows Server 2016 | A third-party product that is not offered or developed by Microsoft | No | Active mode
Windows Server 2016 | Windows Defender AV | Yes | Active mode
Windows Server 2016 | Windows Defender AV | No | Active mode
>[!IMPORTANT]
>Windows Defender AV is only available on endpoints running Windows 10 or Windows Server 2016.
>
>In Windows 8.1 and Windows Server 2012, enterprise-level endpoint antivirus protection is offered as [System Center Endpoint Protection](https://technet.microsoft.com/en-us/library/hh508760.aspx), which is managed through System Center Configuration Manager.
>
>Windows Defender is also offered for [consumer devices on Windows 8.1 and Windows Server 2012](https://technet.microsoft.com/en-us/library/dn344918#BKMK_WindowsDefender), although it does not provide enterprise-level management (or an interface on Windows Server 2012 Server Core installations).
In the passive and automatic disabled modes, Windows Defender AV will continue to run (using the *msmpeng.exe* process), and will continue to be updated, however there will be no Windows Defender user interface, scheduled scans won't run, and Windows Defender AV will not provide real-time protection from malware.
The reasons for this are twofold:
1. If you are enrolled in Windows Defender ATP, [the service requires common information sharing from the Windows Defender AV service](../windows-defender-atp/defender-compatibility-windows-defender-advanced-threat-protection.md) in order to properly monitor your devices and network for intrusion attempts and attacks.
2. If the protection offered by a third-party antivirus product goes out of date, is not updated, or stops providing real-time protection from viruses, malware, and other threats, then Windows Defender AV will automatically enable itself to ensure antivirus protection is maintained on the endpoint.
Therefore, the Windows Defender AV service needs to update itself to ensure it has up-to-date protection coverage in case it needs to automatically enable itself.
You can still [manage updates for Windows Defender](manage-updates-baselines-windows-defender-antivirus.md), however you can't move Windows Defender AV into the normal active mode if your endpoints have an up-to-date third-party product providing real-time protection from malware.
If you uninstall the other product, and choose to use Windows Defender AV to provide protection to your endpoints, Windows Defender AV will automatically return to its normal active mode.
>[!WARNING]
>You should not attempt to disable, stop, or modify any of the associated services used by Windows Defender AV, Windows Defender ATP, or the Windows Defender Security Center app.
>
>This includes the *wscsvc*, *SecurityHealthService*, *MsSense*, *Sense*, *WinDefend*, or *MsMpEng* services and process. Manually modifying these services can cause severe instability on your endpoints and open your network to infections and attacks.
