Are you looking to keep a vigilant eye on your Windows 365 environment? Good news! You can now send Windows 365 audit events to Azure Log Analytics, Splunk, or any other SIEM system that supports it.
Understanding the Scope of Windows 365 Audit Logs
When it comes to monitoring your Cloud PC environment, Windows 365 audit logs are an indispensable resource. These logs provide a comprehensive chronicle of significant activities that result in modifications within your Cloud PC setup (https://intune.microsoft.com/). Here’s what gets captured:
- Creation Events: Every time a Cloud PC is provisioned, it’s meticulously logged.
- Update Events: Any alterations or configurations changes made to an existing Cloud PC are recorded.
- Deletion Events: If a Cloud PC is decommissioned, this action is also captured in the logs.
- Assignment Events: The process of assigning Cloud PCs to users doesn’t go unnoticed; it’s all in the logs.
- Remote Actions: Activities such as remote sign-outs or restarts are tracked for administrative oversight.
These audit events encompass most actions executed via the Microsoft Graph API, ensuring that administrators have visibility into the operations that affect their Cloud PC infrastructure. It’s important to note that audit logging is an always-on feature for Windows 365 customers. This means that from the moment you start using Cloud PCs, every eligible action is automatically logged without any additional configuration.
Windows 365 and Azure Log Analytics
Windows 365 has made it easier than ever to integrate with Azure Log Analytics. With a few simple PowerShell commands, you can create a diagnostic setting to send your logs directly to your Azure Log Analytics workspace.
- Sign in to the Microsoft Intune admin center, select Reports > Diagnostic settings (under Azure monitor)> Add Diagnostic settings.
- Under Logs, select Windows365AuditLogs.
- Under Destination details, select the Azure Log Analytics and choose the Subscription & Workspace.
- Select Save.
Query the Azure Log Analytics
Once your logs are safely stored in Azure Log Analytics, retrieving them is a breeze. You can use Kusto Query Language (KQL) to extract and analyze the data. Here’s a basic example of how you might query the logs:
- Sign in to the Microsoft Intune admin center, select Reports > Log analytics (under Azure monitor)> New Query
- Paste the below query under and click on Run
- Optional you may save the Select Save. to use the query in the future.

Leverage Graph API to retrieve Windows 365 audit events
Connect to MS Graph API
Step 1 – Install the MS Graph Powershell Module
#Install Microsoft Graph Beta Module
PS C:WINDOWSsystem32> Install-Module Microsoft.Graph.BetaStep 2 – Connect to scopes and specify which API you wish to authenticate to. If you are only doing read-only operations, I suggest you connect to “CloudPC.Read.All” in our case, we are creating the policy, so we need to change the scope to “CloudPC.ReadWrite.All”
#Read-only
PS C:WINDOWSsystem32> Connect-MgGraph -Scopes "CloudPC.Read.All" -NoWelcome
Welcome To Microsoft Graph!
OR
#Read-Write
PS C:WINDOWSsystem32> Connect-MgGraph -Scopes "CloudPC.ReadWrite.All" -NoWelcome
Welcome To Microsoft Graph!
Step 3 – Check the User account by running the following beta command.
#Beta APIs
PS C:WINDOWSsystem32> Get-MgBetaUser -UserId admin@wdomain.com
Get entire list of audit events, including the audit actor
To get the entire list of audit events including the actor (person who performed the action), use the following command:
Get-MgBetaDeviceManagementVirtualEndpointAuditEvent | Select-Object -Property Actor,ActivityDateTime,ActivityType,ActivityResult -ExpandProperty Actor | Format-Table UserId, UserPrincipalName, ActivityType, ActivityDateTime, ActivityResult
Get a list of audit events
To get a list of audit events without the audit actor, use the following command:
Get-MgBetaDeviceManagementVirtualEndpointAuditEvent -All -Top 100
Integrating Windows 365 with Azure Log Analytics is a smart move for any organization looking to bolster its security and compliance posture. With the added flexibility of forwarding to multiple endpoints, you’re well-equipped to handle whatever audit challenges come your way.
I hope you will find this helpful information for enabling and quering Windows 365 Audit Logs in Azure Logs Analytics or using Graph API with PowerShell. Please let me know if I have missed any steps or details, and I will be happy to update the post.
