You head to the control panel, users and create a new user of the name you like.
Then you start using that and copy what you want there.
-> NO! You never rename the folder you asked about!
How do you change the User name on a Windows 7 HP computer? I'm talking about when you click on Computer / OS(C / Users / name with padlock next to it. There is no right click/rename option.
I've already gone to Control Panel / User Accounts / and changed the name there - all I see that does is change the name at the heading of the start menu. I'm thinking it's a registry edit, but what and where?
