Last week I noted that Microsoft had released a slew of Preview products for System Center 2012 to take advantage of the upcoming R2 release. If you missed it due to the July 4thholiday, you can still located the download links here: Download the Specific System Center 2012 R2 Product Previews.
Operations Manager and Service Manager rely on Management Packs (MPs) to extend monitoring and management functionality, so just downloading the Preview VHDs you get what you get.

All twenty-one MPs are available for download in a single .MSI file. You can get the .MSI file and a .Zip file containing all twenty-one Management Pack guides here:
