In a workgroup or standalone environment, the Windows XP My Computer icon displays the My Documents folder of another user, displayed as &lt,UserName> Documents, where &lt,UserName> is the logon name of another user.

To prevent this behavior for all users, an administrator can:

1. Open a CMD.EXE window.

2. Type the following command and press Enter:

REG ADD "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer" /V NoSharedDocuments /T REG_DWORD /F /D 1

3. Restart Windows XP.
