Computer name

It is important for computers to have unique names specially when they are connected to a network, so that systems can identify and communicate between each other. Now there are going to be times where you are going to need to change the computer name, for example, because you bought a used computer and it has a terrible name or just because you’ve tired of the old name and you just want to change it.

Changing the computer name in Windows 7 is not a hard process, but there are some things that you want to keep in mind, such as: Try not to choose a really long name, keep it to fifteen characters or less and choose a descriptive computer name. It is recommended to use Internet-standard characters, like using numbers from 0 through 9, letters from A through Z (lowercase and uppercase), and the hyphen (-) character; avoid using just all numbers or spaces, or special characters like < > ; : ” * + = \ | ? , these are invalid ways to name a computer in Windows.
