Patching Windows 2012 Hyper-V 3.0

For a reason unknown to me Microsoft has a number of hotfixes that fix some nasty bugs in Hyper-V 3.0 but aren't' downloaded via Windows update.

Christian Edwards wrote a Technet blog was written to scan for the missing patches a while back, but it was a ball-ache obtaining the individual patches.

Some clever dude has written a PowerShell script to scan the cluster for missing patches, and download them using BITS for your convenience.
