I don't believe it's the same, the full version doesn't care if you have
patch XXX installed, if that patch is part of SP2 then installing the
service pack will reinstall that patch along with all the others. WU
doesn't do that in order to save bandwidth.

So even if they use the exact same piece of code to check, the check is
ignored in the full version of the SP. That's why it takes so long to
install.

Simple enough test though, install the full version a second time and see
if it installs anything, WU won't.
