Hi Dean,

I think the only way to really get rid of the licensing off a computer is to
replace the hard disk.

I've had the experience of reformatting the hard disk - reinstalling the
software and finding that my licence was still in place - Clearly there was
information not in the area of the disk accessible to the format command.

If you do a clean reformat by removing and recreating partitions, the
licence info is gone. But if you use a recovery disk (like Dell's), the
info stays.
