How do I change my name of the directory of my computer (my name)?

C:\Documents and Settings\Emily\My Documents\My Music



How can I permanently change the ';Emily'; there? I just want to change the name altogether. You don't have to tell me steps, just tell me where I can do that.How do I change my name of the directory of my computer (my name)?
The Emily part of the file directory is the user, in order to change that name you must change the name of the user. You do this by going to control panel, then user accounts. Click on the Emily user, then click change my name. This will then update the file directory too. Hope that helps!
