My laptop is registered in my name, how do i change it to my little brother's name without formating the syste

change the 'RegisteredOwner' value in the registry, which is what holds the name that was entered when windows was installed in everything from windows 95 to xp anyways.



instructions for doing this can be found here:

but be careful and follow the guide very closely, mistakes while editing the registry can be dangerous.



the link above does also offer a downloadable tool to make the change safer and quicker.
