Windows 7: Computer Name - View and Change

   Information

Computers on a network must have a unique computer name so they can identify and communicate with each other. If two computers have the same name on the same network, it creates a conflict for network communications.

This tutorial will show you how to view and change your computer name in Windows 7.

You must be logged in as an administrator to be able to change your computer name.

   Note

It is recommend that you use only Internet-standard characters in the computer name. The standard characters are the numbers 0 through 9, uppercase and lowercase letters from A through Z, and the hyphen (-) character. Computer names cannot consist entirely of numbers, nor can they contain spaces. The name also cannot contain special characters, such as the following:

` ~ @ # $ % ^ & ( ) = + [ ] { } | ; : , ‘ “ . < > / ?

   Warning

Some Internet service providers (ISPs) require you to use a specific computer name so they can identify your computer and validate your account. If your ISP requires a specific computer name, then do not change the name they give you.
