@Bharat Suneja,
One of the great new feature in PoweShell 4.0 is DSC, where you can use build-in DSC Resources or create your own to declare the configuration of a system.
As I`m aware the Exchange team is pretty innovative with PowerShell, so I was thinking what about leveraging this PS DSC feature to declare the exchange configuration, so it can be auto-remediated on regular basis.
It will be extremely useful in large deployments or multi-tenant deployments in *-cloud environments.
It will be also very easy to migrate the configuration from DEV to Test and to Prod Environments.
And also as some of the settings are reverted when you install new CUs, they will be auto-remediated on regular basis.
