Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

On Windows XP, I changed my user account name but still the old user is working. I even changed the computer name and ID to my name, but everywhere I can see the old user name.

When I log in and write my new user, it works fine.

I even restarted my PC.

Did you change the name of your current user or did you create a new user account? If you created a new account, you must deactivate the old account. –  Raystafarian Feb 6 '12 at 13:11
Your question really is not clear. Can you show us some screenshots maybe, as an example? –  slhck Feb 6 '12 at 13:14

You only changed the „display name” of the account, not the real login name.

how i can change the real login name? –  khalid Feb 7 '12 at 6:41
@khalid You don’t. –  kinokijuf Feb 7 '12 at 15:53

Renaming a user only changes the "label" of the user. In the background each user has a SID (security identifier) which is constant.

Because it retains its security identifier (SID), a renamed user account retains all its other properties, such as its description, password, group memberships, user environment profile, account information, and any assigned permissions and rights.

If you mean the user profile name remains the old one, that is expected. So if old user was User1 and you changed it to User2, the account name will change and you log on as User2. However, the profile in documents and settings will remain User1. User1 will still appear in other places but the account User1 does not really exist
