To create a duplicate of an user profile with a different user name, try this:

• Create a new user account
  
• Logon to that account to initialize the newly created profile
  
• Log off from the newly created profile
  
• Login as built-in Administrator
  
• Open Control Panel System applet
  
• Click the Advanced tab
  
• Click Settings under User Profiles
  
• Select a profile to copy from and choose Copy To
  
• Browse to the profile to copy to (C:\Documents and Settings\username)
  

A new profile is now created which is the duplicate of your user profile.

Thats interesting. I havent heard of this before. Thanks for sharing
