Validating Hyper-V 2012 and Failover Clustering Hotfixes and updates with Powershell - Part 2

Hello again!

During the last week I did some test with the script and I realize that is not handy to type a bunch of server names when you need to analyze big Clusters, so i decided to create a V2 of the script specifically for Clusters. I think this will like to lazy people like me that hates to type 16 servers names when all of them belong to the same cluster.

This V2 script only requires the name of the 2012 Hyper-V Cluster you want to analyze and automatically will collect the hotfixes from all nodes and will compare with the list already mentioned in my last post. https://blogs.technet.com/b/cedward/archive/2013/05/24/validating-hyper-v-2012-and-failover-clustering-2012-hotfixes-and-updates-with-powershell.aspx

Here is the V2 script that only requires the Cluster Name

  I have customized your script and xml files a bit and posted on my blog to create powershell objects and possible download the updates/hotfixes :-) vniklas.djungeln.se/.../hotfix-and-updates-check-of-hyper-v-and-cluster-with-powershell

  Any chance you could put URLs up for just the 2 XML files so that a script could pull them down and make sure it's the latest one?

  a version for 2012R2 would be really nice :) Keeping up with the hotfixes is a real PITA, so your work here is really appreciated
