Patches are assigned to incorrect OS.
When setting up a smart label for patches and using the field of "Operating System" I then set that to a value of "Win 2012 R2 SP0 x64" which will incorrectly include patches for Server 2012. Most patches are labeled as applying to both OS. Which isn't correct. For example. KB3161561 has a patch for 2012 and another one for 2012R2. Both are classified as applying to both OS when it should be a one to one relationship.
