' # $ % ` ( ) + /. If ComputerName is not specified, a random computer name is generated. After OOBE, end users can change this default computer name after OOBE by changing it in the System Properties page. To set a default computer name pre-OOBE, OEMs can configure ComputerName in the Unattend.xml file and specify a name for the computer. In Windows 10, users can no longer enter a computer name during OOBE as the name is auto-generated.
