Hello Joseph Molloy
Yes, you can download a trial version of Windows Server 2019 from the Microsoft Evaluation Center website first. As for downloading a trial license, Microsoft does offer a 180-day evaluation version of Windows Server 2019 that you can download and use for testing purposes. However, it is important to note that this evaluation version cannot be used in a production environment and must be replaced with a licensed version before the evaluation period expires.
To license a VM running Windows Server 2019, you will need to purchase a license key from Microsoft or a Microsoft reseller. Once you have the license key, you can activate the VM by entering the key in the Activation settings of the Windows Server 2019 VM.
