I recently bought a new laptop with Windows 7 Home Premium and a Windows 7 Pro Upgrade key. It also comes with a cavalcade of bloatware. I would like to start with a fresh install of Windows.

I understand that I can upgrade to W7Pro using the option in the Home Premium Start menu. However, I also own a Windows 7 Pro OEM installation disc from another computer. Can I use this Windows 7 Pro OEM disc to install Windows, and when it asks me for my key, provide the upgrade key purchased? Or am i required to install Home Premium first and then apply my upgrade key?
