Microsoft also uses Akamai to host a lot of the Windows Update stuff. 
It's probably the "Automatic Updates" service checking to see if there
are any patches available, which it would then either silently download
and install, just notify you about them, or do nothing at all, depending
on your settings.   :/

If you Google for Akamai and Windows Update you'll get a bunch of news
about when MS switched to using Akamai to host that content.  Here's one
article on /. that has a tiny bit of info.
