Live Update question

Is there a way I can determine what updates and their size, are being applied to my PC?  I went to Live Update today and there were 8 updates.  It took about 35 minutes for the updating to complete?  I am running NIS 22.5.4.24 on a Windows 7 PC, using Firefox 42.0.  Updates 1 through 7 went quickly but the update 8 of 8 took over 30 minutes by itself?
