Windows Server 2012 comes into 2 different editions (Datacenter, Standard) on MSDN/TechNet installation DVD. The evaluation DVD can be downloaded via the TechNet Evaluation Center. You can burn this .iso file using for example ImgBurn. After burning the DVD follow the installation steps below.
8. After the installation has finished you will be asked to enter a password for the built-in Administrator account. You MUST type in a strong password with at least one capital letter and one number, for example P4ssword (capital P/number four), otherwise you will get an error message saying that your password does not meet the password complexity requirements. You can disable this strong password enforcement later. Click Finish to apply the new password.
10. In the Server Manager click Manage in the upper right, choose Server Manager Properties and check Do not show me this console at logon to not show the Server Manager at start-up. You can access the Server Manager later via the the shortcut in your pinned items bar or Start screen.
