Probably the easiest way to do this is to use the Easy Transfer Wizard for Windows 7. This copies all the user setting from Windows XP into Windows 7.
You’ll have to download the Easy Transfer Wizard software from Microsoft and install it on your Windows XP machine. Then connect a USB hard drive – buy a new one if you haven’t already one for backup – and run the wizard. Tell it to save the files to the external USB drive.
Once the Easy Transfer Wizard is complete, connect the external drive to the new Windows 7 computer and run the Transfer Wizard. Microsoft have instructions how to run the Wizard on Windows 7.
Remember you’ll need a copy of Microsoft Office on your new computer so you can run those Outlook files. Make sure you’ve installed Outlook and run all the Windows 7 and Microsoft Office updates before running the file transfer wizard.
