Hey all, This is my first official post on here and I've been curious about something. I have two discs here of Windows SBS 2011 Essentials that have two different 'buildlabex' numbers as found in the registry. One was downloaded and burned last year (2011) and one was recently downloaded and burned just last week. Does anyone know the official difference between the two? Here are the build numbers: 7601.17592.amd64fre.win7sp1_gdr.110408.1631 (downloaded 2011) 7601.17803.amd64fre.win7sp1_gdr.120330-1540 (downloaded 2012) The earlier one isn't a beta or RC release is it?
