Control Panel - System & Security - Administrative Tools - System Information
You can use Cortana to launch Control Panel since they removed most direct methods.
The System Information tool is not the same as other methods for getting System Info.
The CPU will also put you onto the Model except some SP2 and SP3 models used the same CPU no other ones have.
Update: Also on the list view of the Start Menu there is a folder "Windows Administrative Tools" that contains the same tools from the Control Panel - Administrative Tools.
