If you are not currently using these MP’s, there is or update them.
If your agents are placed into pending management – this is generally caused by not running the update from an elevated command prompt, or having manually installed agents which will not be placed into pending.
In this case – my agents that were reporting to a management server that was updated using Windows Update – did NOT place agents into pending.
I recommend using the manual approach and not using Windows Update, for several reasons.
Windows Update applied patches will not put agents into pending updates, and is more difficult to precisely control.
I simply make sure I only patch one management server at a time to allow for agent failover without overloading any single management server.
