Hello
Thank you for your question and reaching out.
Only server licences have ever been included in the price of a VM in Azure; client OS licences have never been. You will need to bring your own licences if you want to use Windows 10 virtual machines. For Windows 10 licences, you need Windows 10 Enterprise E3/E5 per user or Windows Virtual Desktop Access per user (User Subscription Licenses or Add-on User Subscription Licenses).
