How to tell if Windows is Retail or OEM?

I'm looking to install a new motherboard and processor into my PC however I've been told the licence for Windows 7 is assigned to the motherboard, therefore if I have an OEM version this will not work with the new parts. Unfortunately I've lost my Windows 7 disc though I still have the product key and product ID. Can anyone tell me how I would find out if my version is Retail or OEM please? I've heard that the letters OEM appear in the product ID if it is an OEM version (which don't in my case), is this correct? Finally, as I've lost the disc, can I download a copy of Windows 7 and use my product key?

Thanks in advance for any help!

Assuming that your system is still working, right-click My Computer and select Properties.  Scroll down to the bottom of the screen and find the Product ID. 

The Product ID should be in the form xxxxx-xxx-xxxxxxx-xxxxx.  What are the 3 characters in the second group (if those 3 characters are OEM, then you have an OEM version).

You can also run MGADiag from Microsoft --> http://go.microsoft.com/fwlink/?linkid=52012
