COA product key and installed product key discrepancy
On a recently purchased, from a supplier believed to be reputable, refurbished 64 bit, Win 7-Pro, computer, the product key shown on the affixed COA and the product key retrieved with Magical Jelly Bean are different. In various places I have searched, I think I have learned that this often happens when big refurbishers use special OEM product keys when they refurbish PCs and install newer operating system software. Is this information still correct?
What happens if I choose to replace the existing HD in the PC after a HD failure or if I want a larger HD in the PC? Will the product key on the affixed COA work?
Should I, for the moment, 1) attempt to reactivate the OS with the product key on the affixed COA; 2) do nothing; 3) or something else?
Thank you, in advance, for comments, suggestions, or pointers to an appropriate tutorial.
