  1. Evaluation Versions: Microsoft offers evaluation versions of Windows Server 2019 that can be used for free, for a limited time (usually 180 days). This can be a great way to test the software and its capabilities.
  2. Azure Virtual Machines: Microsoft Azure offers a free account with limited services, including the ability to deploy a Windows Server 2019 virtual machine. This can be a viable option for learning and testing purposes.

Usage: You can download a fully functional ISO or VHD file for Standard or Datacenter editions. Duration: The version is valid for 180 days.
