Q&A Problem: How to completely change the XP system username

User problem: In the "Control Panel""User Account" changed the user's name, but the original is still displayed in the Task Manager Username, why is this?

Xiaobian Answer: In Windows XP, the username includes the name displayed and the real username. The only change in the "user account" is the name displayed, which will appear on the "Start" menu and "Welcome screen". In the task manager, the user name is displayed. If you want to change the user name, you can run "control userpasswords2", select the account that needs to be changed, click the "property" button, and then in the pop-up properties dialog box. Change the "username" column.
