When running a SCOM 2012x environment, whether RTM, SP1 or R2, it’s always important to be on the latest level of the available Update Rollup Packages.
But what UR is the latest for SCOM 2012 RTM, SP1 or R2? Gladly KB2906925 tells it all. Per release all URs are listed, together with the download link and whether or not it contains updates for SCOM or not (some URs for System Center 2012 didn’t contain updates for SCOM).
Go here to see whether your SCOM 2012x environment is running the latest UR.
Be careful though. When a new UR is out TEST it thoroughly before rolling it out in production. And just waiting a few weeks before applying it will also help in order to prevent some hidden ‘features’ .
