Even though there was seven bulletins, 3 of them had multiple updates. For example MS12-034 had 4 updates for Windows XP OS alone plus .net Framework versions, Office and Silverlight. In theory, you could have maybe a dozen updates to install for a single bulletin. MS12-030 and MS12-035 have also multiple updates. When I first saw six bulletins I thought it was a "light" month. I was wrong [of course the advance notification Email doesn't give any idea on how many actual updates.]. Odly I had some old .net framework updates to reapply.
