ComputerName specifies the computer name used to access the computer from the network.

Values

If ComputerName is missing, you must enter a computer name during OOBE.

If ComputerName is set to an asterisk (*) or is an empty string, a random computer name will be generated. This random name has at most eight characters from the RegisteredOwner and/or RegisteredOrganization strings plus random characters.

ComputerName is a string with a maximum length of 15 bytes of content:

  • ComputerName can 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.

  • ComputerName cannot use spaces or any of the following characters: { | } ~ [ \ ] ^ ' : ; < = > ? @ ! " # $ % ` ( ) + / . , * &, or contain any spaces.

  • ComputerName cannot 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.

Note

  • In Windows® 8 and Windows Server® 2012, computer names are no longer appended by an OEM string.

  • In Windows® 7, Windows Vista®, Windows Server® 2008 R2, and Windows Server® 2008, computer names can be customized by OEMs and by corporate customers. They can append a string that is up to five bytes long to the customer-chosen computer name.

    If you do not customize this string, "-PC" is appended to the customer-chosen computer name. In some languages, "-PC" is localized and the resulting string might be more than five bytes. When this occurs, the computer-name string is truncated and this truncation may result in a nonsense string appended to the computer name.

    To avoid this situation, OEMs and corporate customers should provide an appending string in an Oobe.xml file.
