Delete a host pool

To delete a host pool in the Azure portal:

1. Sign in to the Azure portal.

2. Search for and select Azure Virtual Desktop.

3. Select Host pools in the menu on the left side of the page, then select the name of the host pool you want to delete.

4. On the menu on the left side of the page, select Application groups.

5. Select all application groups in the host pool you're going to delete, then select Remove.

6. Once you've removed the application groups, go to the menu on the left side of the page and select Overview.

7. Select Remove.

8. If there are session hosts in the host pool you're deleting, you'll see a message asking for your permission to continue. Select Yes.

9. The Azure portal will now remove all session hosts and delete the host pool. The VMs related to the session host won't be deleted and will remain in your subscription.

To delete a host pool using PowerShell, you first need to delete all application groups in the host pool. To delete all application groups, run the following PowerShell cmdlet:

Remove-AzWvdApplicationGroup -Name <appgroupname> -ResourceGroupName <resourcegroupname>

Next, run this cmdlet to delete the host pool:

Remove-AzWvdHostPool -Name <hostpoolname> -ResourceGroupName <resourcegroupname> -Force:$true

This cmdlet removes all existing user sessions on the host pool's session host. It also unregisters the session host from the host pool. Any related virtual machines (VMs) will still exist within your subscription.

To delete a host pool using the Azure CLI, you first need to delete all application groups in the host pool.

To delete all application groups, use the az desktopvirtualization applicationgroup delete command:

az desktopvirtualization applicationgroup delete --name "MyApplicationGroup" --resource-group "MyResourceGroup"

Next, delete the host pool using the az desktopvirtualization hostpool delete command:

az desktopvirtualization hostpool delete --force true --name "MyHostPool" --resource-group "MyResourceGroup"

This deletion removes all existing user sessions on the host pool's session host. It also unregisters the session host from the host pool. Any related virtual machines (VMs) will still exist within your subscription.
