NIS 2013 tried install something Hotfix - but what was that?

Hi,

 

Seems that when I run Liveupdate it download something hot fix what was called 2013 FF.

 

So I left my computer running about in 1 hour but still that same hotfix insallation was going. So I deciced boot my computer and try again Liveupdate but that didn't find anything new files. So what was that patch and how I can check that was installed on my computer now?
