what they are trying to tell you is that some reg keys are left behind
and that even if you new where and what they were manual removal is riskier then re formatting the only problem is that it takes a while

if you know your way around a computer I would go for formatting the unit
but if you don't take it to some place that does
if you don't get a good install from the start you will have to do it all over again

I do this for a living and once in a while I come across a unit that we have had to re install 3 times before it took a good install


good luck on what ever you do
