Hi,
1. Server Manager -- Add roles and features -- Role-based -- Server Roles -- Remote Desktop Services -- select RD Session Host and RD Licensing Role Services -- finish wizard. Restart
2. Open gpedit.msc. Set the licensing mode to match the type of purchased RDS CALs you have, and Specify the FQDN of your RD Licensing server (localhost is fine in your case)
Computer Configuration\ Administrative Templates\ Windows Components\ Remote Desktop Services\ Remote Desktop Session Host\ Licensing\
Use the specified Remote Desktop licensing servers Enabled
Set the Remote Desktop licensing mode Enabled
3. Open RD Licensing Manager (licmgr.exe). Activate the server, then Install your purchased RDS CALs

If the administrator does not want users to change the settings, the administrator can apply a restriction by using the Administrative templates in the GPO.
An administrator must also combine GPOs, an organizational unit, a user, or a computer by implementing both a Preference mode and a MAINTENANCE MODE GPO.
