Q: Why does a message in System Center Operations Manager 2012 Administration overview tell me to Upgrade to full version?
A: When you install System Center 2012 Operations Manager, there's no way to enter a product key, so initially the installation is in trial mode. To enter a code, you need to use Windows PowerShell (this is documented at the Microsoft support site).
Essentially, you need start an Operations Manager PowerShell session. You will see something similar to the following, and will then need to imput the code below:
Welcome to the System Center Operations Manager 2012 Command Shell. This command shell is
designed to provide interactive and script based access to Operations Manager
data and operations. This functionality is provided by a set of Operations
Manager commands.
To list all commands, type: Get-Command
To list all Operations Manager commands, type: get-command -module OperationsManager
To get help for a command, type: Get-Help [command name]

You can check the status; however, it will likely still show Eval mode.
The solution is to reboot.
Then the correct SKU will show.
