Choose Windows Server as shown in the picture.

In the Networking setting, you should check the Assign Public IPV4 Address option so that it can get a public address.

Then set the login username and password in System Configurations. You can remote connect this server using the IP address and password.

4. When all the settings are done, you can preview them before submitting, and the total amount should be 0.00 USD. The server will be created within 1-5 minutes of submission.
