Hi,
I am trying to reinstall windows7 in my computer, but I don't know the product key. I misplaced the windows original CD.
My machine has windows7 Professional OEM version, and I want clean reinstallation .
How can I extract product key from this computer before I reinstall windows? I know it is in the registry womewhere in this machine, but if I reformat, then I need to input the product key and I don't know have any record about the product key.
