Start Windows Easy Transfer on your old PC (the PC that you want to
                transfer your files and settings from). During the transfer process, Windows Easy
                Transfer will estimate how much disk space is needed to transfer your selections.
                If you use a USB flash drive, it's best to use one with enough storage space
                for the entire transfer. If your USB flash drive isn't large enough to transfer
                everything at once, you can copy as many files as it will hold, transfer those files
                to the new PC, and then reconnect the drive to the old PC and repeat
                the process.
