you could try the settings and files transfer wizard.
Log into the account you want to save
Start > All Programs > accessories > sysem tools > Files and Settings transfer Wizard.
tell it that this computer is your "old computer"
Unblock the wizard in the firewall dialogue if it asks
Select other for the location
Put it somewhere you will remember where it is > next
If you want a complete transfer then click next.
It will then take a few minutes or so to collect the data.
once it is finished, log out and log in to your new login.
run the wizard again, this time stating it is your new computer.
point it to the folder you put the files and settings in before (not the numbered sub-folder)
and follow through the wizard and viola you should have an identical desktop
