Ineffective Change of Windows User Name

[MislikerVinduer]

I have changed my Windows (7 HP) user name, i.e. the name of the only user account, from, be it, 'James' to 'Alex'. I have even changed the computer's name to 'Alex'.

When creating, be it, a PDF file, the file's information tells that the owner is 'Alex\James'. In other words the old and apparently removed account name is still in use.

A place it says (translated into English): 'User profiles on this computer: (...) Alex\James'. This profile has a size of, be it, 30 GB, whereas my C drive has 60 used GB.

I want 'Alex' to own and/or to be the author of documents, images, and other files I create. I have read similar topics in this forum, but they did not help me much. I appreciate your assistance.

I've never had any luck changing an account user name in any flavor of Windows. Unfortunately Create a New Account, configure it the way you want, then delete the old account still seems the be the only reliable method.
