I have a Lenovo notebook with pre-installed Windows 7 Professional x64.

I just did a clean reinstall with retail installation Win7 Professional x64 disk I got from MSDNAA programme I'm member. I wanted to install the OS as Lenovo OEM with the same key I had before, but when I tried to activate the newly installed Windows, it gave me 0xc004e003 error.

So the question is, can I use my OEM key for Win7 installed as retail? If not, can I somehow change the installed OS to OEM?

The other think is, the OEM key I have tried is just some key I found in my notes, because I don't have any Windows sticker on beneath my laptop as it used to be on all my previous ones. Can I somehow find out "what is the origin" of the supposed key I'm trying to use?
