On the replacement HD I have installed a Full version of Windows 7 Home edition that was intended for my wife's laptop, whereas I had wanted to install an Upgrade version of Windows 7 Ultimate. I was not aware of this post and have stupidly entered the product key and it has activated. I am now unable to upgrade with the genuine Ultimate disk.

The second is a Confirmation ID, assigned by Microsoft, and is used to activate the operating system’s software. This method is used when upgrading or installing a new Windows edition from disc (not HP System Recovery).
System Locked Pre-installation (SLP) takes place at the factory. No intervention is required to activate the operating system software before initial use. With SLP-activated systems, most of the computer's hardware can be replaced without needing to re-activate the software through Microsoft.
