OMS (Microsoft Operations Management Suite) pushes management pack updates automatically down to your on-premise SCOM, as part of Microsoft's rapid releases.
Unfortunately there is no easy way to see when this happened, so *if* something broke - it's harder to associate with a change.
(change control - time for a rethink?)
I threw together this script to query the SCOM database and return any MP updates in the last 24 hours. And then built an alert in SCOM to tell me if it had any results from that script.
