As stated earlier, SCOM 2012 R2 UR#7 was withdrawn by Microsoft since some issues were reported.
Yesterday Microsoft released the ‘fixed’ version of UR#7 for SCOM 2012 R2 as KB3064919. It contains some security updates as well this UR, among quite a few fixes.
Also the new branding of Operations Management Suite (OMS) is to be found in this UR. So Operational Insights is no more in SCOM 2012 R2 after applying this update.
Even though this UR is highly recommended, I urge you to TEST it first in a SCOM test environment before applying it in production. But that’s just me…
