# Collect Update Compliance diagnostic data for Windows Defender AV Assessment
**Applies to:**
- [Microsoft Defender Advanced Threat Protection (Microsoft Defender ATP)](https://go.microsoft.com/fwlink/p/?linkid=2069559)
This article 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 [Troubleshoot Windows Defender Antivirus reporting](troubleshoot-reporting.md), met all require prerequisites, and taken any other suggested troubleshooting steps.
On at least two devices that are not reporting or showing up in Update Compliance, obtain the .cab diagnostic file by taking the following steps:
1. Open an administrator-level version of the command prompt as follows:
a. Open the **Start** menu.
b. Type **cmd**. Right-click on **Command Prompt** and click **Run as administrator**.
c. Enter administrator credentials or approve the prompt.
2. Navigate to the Windows Defender directory. By default, this is `C:\Program Files\Windows Defender`.
3. Type the following command, and then 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. By default, the location is `C:\ProgramData\Microsoft\Windows Defender\Support\MpSupportFiles.cab`.
5. 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.
6. 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:

## Redirect diagnostic data to a UNC share
To collect diagnostic data on a central repository, you can specify the SupportLogLocation parameter.
```Dos
mpcmdrun.exe -GetFiles -SupportLogLocation <path>
```
Copies the diagnostic data to the specified path. If the path is not specified, the diagnostic data will be copied to the location specified in the Support Log Location Configuration.
When the SupportLogLocation parameter is used, a folder structure as below will be created in the destination path:
```Dos
<path>\<MMDD>\MpSupport-<hostname>-<HHMM>.cab
```
| field | Description |
|:----|:----|
| path | The path as specified on the commandline or retrieved from configuration
| MMDD | Month Day when the diagnostic data was collected (eg 0530)
| hostname | the hostname of the device on which the diagnostic data was collected.
| HHMM | Hours Minutes when the diagnostic data was collected (eg 1422)
> [!NOTE]
> When using a File share please make sure that account used to collect the diagnostic package has write access to the share.
