ComputerName specifies the computer name used to access the computer from the network.
Note
In Windows 10, users can no longer enter a computer name during OOBE as the name is auto-generated. To set a default computer name pre-OOBE, OEMs can configure ComputerName in the Unattend.xml file and specify a name for the computer. After OOBE, end users can change this default computer name after OOBE by changing it in the System Properties page.
Values
If ComputerName is not specified, a random computer name is generated.
If ComputerName set to an asterisk (*) or is included but empty (""), Windows creates a random 15-character name using up to 7 characters from FullName and Organization, then a dash, then more random characters.
ComputerName is a string with a maximum length of 15 bytes of content:
ComputerNamecan use ASCII characters (1 byte each) and/or multi-byte characters such as Kanji, so long as you do not exceed 15 bytes of content.ComputerNamecannot use spaces or any of the following characters: { | } ~ [ \ ] ^ ' : ; < = > ? @ ! " # $ % ` ( ) + / . , * &, or contain any spaces.ComputerNamecannot use some non-standard characters, such as emoji.
Computer names that cannot be validated through the DnsValidateName function cannot be used, for example, computer names that only contain numbers (0-9). For more information, see the DnsValidateName function.
