Troubleshooting

This article provides suggestions for troubleshooting Windows 365 issues.

Contact help/support

For instructions on how to get help and open a support ticket, see How to get support in Microsoft Endpoint Manager. Support is included as part of your Windows 365 subscription.

Since Cloud PCs work like most physical devices, you can use existing troubleshooting documentation to troubleshoot issues with Windows client, Microsoft 365 services, and Microsoft Endpoint Manager admin center.

Audio and video redirection not working

For connections using the Remote Desktop client for Windows to access Cloud PCs, the first time a user signs in to their Cloud PC, Microsoft Teams will be installed.

After the installation, the optimizations to redirect audio and video to your local Windows endpoint don’t work. The user must close Teams and sign out from or restart the Cloud PC to activate the Optimized status.

Conditional access

Make sure that you apply conditional access policies to both the dedicated Windows 365 cloud app and the Azure Virtual Desktop cloud app. You can apply these policies in the conditional access UI of Microsoft Endpoint Manager admin center or Azure Active Directory.

Any conditional access policy that you apply will affect:

  • Access to the end-user web portal
  • The connection to the Cloud PC from the Remote Desktop apps.

For more information about service dependencies in Azure AD Conditional Access, see Conditional Access service dependencies.

Applying a more restrictive policy to Azure Virtual Desktop than the Windows 365 cloud app will result in Azure AD honoring the more restrictive policy. This policy will affect end user connectivity to their Cloud PCs after accessing the Windows 365 end user portal.

For more information on how a given policy may affect your environment, see Troubleshoot using the What If tool in Conditional Access.

Help users in your organization

You can use the Intune Troubleshooting page to view enrollment issues, remediation steps, and user details. For more information, see Use the troubleshooting portal to help users at your company.

App Assure is a service for Microsoft’s enterprise customers who encounter application compatibility issues. App Assure will help remediate issues with your ISV, line-of-business and Microsoft-developed apps at no extra cost. If you encounter any app compatibility issues, follow the instructions above to submit a case and include a short description of the issue.

Language pack installation failed

You can try either of these possible solutions:

  • If the language pack installation failed, try reprovisioning the Cloud PC to install the language pack again.
  • Check to see if there's an Attack Surface Reduction rule set on Intune. If the Block process creations originating from PSExec and WMI commands is set to Block, it will block language pack installation. You can remove the rule and retry provisioning, or provisioning with default language set to en-us. Then, let the user change the language by using the Windows Settings App in the Cloud PC.

Networking

The Azure network connection checks help to make sure that network connectivity is working. Always retry the Azure network connection if you suspect networking issues might be causing issues. Using the Azure network connection checks helps make sure that repeated and consistent checks are used as the first troubleshooting step.

Keep in mind that the Azure network connection checks are validating the infrastructure configuration of your environment. They don't run checks to validate any extra configuration or applications deployed to Cloud PCs after provisioning by Microsoft Endpoint Manager or third party agents. These agents or configurations can introduce other issues that the Azure network connection can't test for ahead of provisioning.

For example, if you deploy a VPN client to all devices in Microsoft Endpoint Manager, make sure that this client doesn’t:

  • Break connectivity to Azure Virtual Desktop endpoints required by Windows 365.
  • Exclude your Cloud PCs for having the VPN client deployed to them.

Finally, consider temporarily deploying a test Azure virtual machine to the Azure network subnet that you’re trying to provision or connect to your Cloud PCs. This test machine will let you run all the network tests that you require from that network. You can use the PowerShell Test-NetConnection command to test connectivity on specific ports to specific network endpoints/URLs:

Test-NetConnection <hostname> -Port 443

Troubleshooting by end users

The end user can troubleshoot some issues that might be preventing them from connecting to their Cloud PC. For more information, see End-user actions

Video playback improvements

You can improve video playback performance on your Cloud PCs by using multimedia redirection (MMR).

For Cloud PCs, MMR is supported on the following platforms: Windows, macOS, ChromeOS, Linux.

For more information, see Multimedia redirection for Azure Virtual Desktop.

MMR is in public preview for Windows 365 Cloud PCs.
