Change Your Computer Name
If your computer is configured with a name that no one can recognize (for example, a string of unrelated letters and numbers), you may decide to give your computer a more intuitive or personal name. Open System in Control Panel, then click Properties on the Network Identification tab. In the "Computer name" field, type a new name for the computer and click OK. If the computer is a member of a domain, you will be prompted to provide a user name and user password to rename the computer. You must be logged on as an administrator to the local computer to change the computer name.
