在Windows上获取当前的用户名

Question

I modified my username in Control Panel -> User Accounts -> Change Your Name.

But when I use the GetUserName function, it returned my old username.

How do I get the new one?

EDIT 1

Here's the code as requested:

char user[UNLEN + 1];
DWORD user_len = UNLEN + 1;
GetUserName(user, &user_len);

Answer 1

Try to use the API GetUserNameEx , and passing as a format NameDisplay . I guess you changed the display name of the user, not the logon name.
