But isn't that quite a big difference? MiKTeX will actively download and install the extra package for you there and then, whereas with TeXLive you'll need to rerun the installer (?) or download the packages from CTAN?
I must admit I speak as a Linux user who's installed TeX on Windows machines, but not really gone into detail myself, so please correct me if I'm wrong.
