Get some software like Nero or the free CD burner XP pro..
CDBurnerXP: Downloads

Open Cd burner XP pro, Select data disc, drag the contents of whatever u want as ISO to the bottom space.
Click File > Save compilationas ISO file

Tada

PowerISO is what i use mainly.

i find LC ISO creator is brilliant. It's standalone so you dont need to install anything, nice and simple to use, only about one button on it :P
and its free
