I might as well admit I only have a very vague understanding of what .NET is. And, I can't see why I would need it based on the information on Microsoft's page for the KB article (shown above). The information there gives me the impression this of interest mainly to developers. And, I'm not a software developer.

 

I know this:
KB2750149 is NOT on any watch list as being potentially problematic for an end user.

Microsoft has released (via Windows Update) KB2803748 to repair an issue with Windows Server 2012 - Failover Cluster Manager (FCM) caused by KB2750149.

I would forgo it unless/until it appeared to be need for functionality...
