Hi blokes,
To help you to get hold of all your data placed to the new PC, which runs on Windows 7, Microsoft permits you to make use of the software system Windows Easy Transfer. The software will actually obtain a single file containing all your data which can then be moved to the other PC using either LAN or to an external hard disk via a USB port. The use of this software is focused basically to PC owners having XP because without this it is impossible to upgrade to Windows 7 without formatting everything. Windows Vista users can also use the program to make an easy transition to Windows 7.
i saw this site that contains the step on how exactly to do it
