This appears to be folks from within Microsoft Testing and they're doing so much of it that it's really having an impact on my referral data. Not that I don't mind the referrals but these don't appear to be legitimate.
Is anyone else seeing this type of activity?

I am getting the same thing. Check the sites that do rank for those terms you might be on one of them. Somebody told me that if someone goes to a site from live.com and then clicks on a link on that site the referrer would be from live instead of the site that the link was on.
