How to View and Change the "Computer Name" in Windows 7


information   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   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   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.


EXAMPLE: Computer Name
NOTE: This is in the System window from the Control Panel.

11. After the restart, verify the new computer name.

2. In the elevated command prompt, type the command below, and press Enter. (see screenshot below)

Code:
wmic computersystem where name="%computername%" call rename name="Computer-Name"

I have two (separate) issues when changing the computer name on two (separate) systems I'm working on.

On a desktop (W7 x64), when I change the computer name it hangs considerably at boot (hangs at the spinning circle at the "Welcome" screen that at least doubles the boot time). It doesn't seem to iron itself out after several reboots (like if it were a router connection issue and needed a new address assigned). Nothing significant in the event log. If I change back to the original computer name, everything is fine again.

Then, on a laptop (W7 x86), when I change the computer name the boot is fine, but it hangs at shutdown "Logging Off." It hangs there permanently requiring a power-off. Changing back to the original computer name returns things to normal for this one also.

Any ideas for either of these?
Tom

Hello Tom,

Not sure why, but depending on how you have your network setup, you might check to see if you may need to reassign a IP address for your desktop computer connection. The router may still be seeing it with the old computer name.

Hope this helps some,
Shawn

That's a good point, Shawn. At the time I might have set a DHCP reservation on the router for the Desktop and that might have caused some confusion. I'll work more in that area if I try changing the computer name again (I've just left it as it is for now).

As for the laptop, that's currently more important and has me frustrated. I won't complete logging off even with all network adapters disabled, so I think it's having issues logging off the user account rather than the network.

Tom,

I suppose that you could create a new administrator account on the laptop to test to see how it logs off from it to see if does the same.

Hello Jonathan,

They are the same thing. You'll notice as you type the computer name in, it will also change under "Full computer name".
