I'm not asking this because I have looked up porn or have done something bad on the computer I'm only curious to know. My parents have set up 'Windows Live Family Safety' on my computer so I was wondering even if I delete my history are they still able to see what I have done? And also are they able to see every little detail I do, meaning not only the websites I visit but also the things I type and things like that?

In short, YES.

So meaning they can see EVERYTHING?

So meaning they can see EVERYTHING?
I did some research, and yes, they can.

I've been messing around with computers since 1980.

And yes... there are many ways they can find out where you have been, so the solution is stay away from any place you don't want someone to know you've been too. And not just your parents will know...and you would be shocked to know just how many and who.

Yes, very easily.
