I’m not sure if there is much difference when renaming a computer in Windows XP, Windows Vista, Windows 7, Windows 8.x, or in Windows 10. Giving a unique name to your computer is important when connecting to a network or local area network because it is used to identify your machine. To rename your computer, click “Start”, “Control Panel” then select “System”.
If you don’t see this, switch view to either “Large icons” or “Small icons”. Next, locate “Computer name, domain, and workgroup settings” section then click “Change settings”.
On the next screen, in “System Properties” window, in “Computer Name” tab, click “Change”. On the next screen, in “Computer Name/Domain Changes” window, enter your computer’s new name in the “Computer name” text field then click “OK”. And that’s it.
