When you import a VM with Windows installed on AWS, you generally need to provide your own Windows license. AWS doesn't typically include the Windows license as part of the VM import process. So, you would need to have a valid Windows license that allows you to run Windows on AWS.

Regarding the Client Access License (CAL) licenses, it's important to note that CALs are typically associated with Windows Server rather than the Windows client operating systems like Windows 10. If your VM is running a Windows Server edition, you may need to ensure that you have the appropriate CALs for the number of users or devices that will be accessing the server's services. I had faced license issue once when i was working with moodle installation.
