I opened an Azure account many, many years ago and it has been dormant. At the time, a virtual machine was either a Windows or a Linux server, is that correct?
Now, there is Virtual Windows Desktop. Is that simply the virtual Windows Server presenting a familiar desktop UI?
Then, there is Virtual Windows Desktop Multi-User Sessions? Is that multiple virtual windows desktop clients connected to a virtual windows server? Or, is that somehow a desktop that is supporting multiple users working concurrently?
