Recovering Serial Number
No
If you loose your serial number support will never give you a replacement. But if a situations arises where you need to proof ownership they have alternative ways. It basicly consist of a long and irritating list of questions. I have seen it once (it changes on regular basis) and it contains many things that seems to be bogus to me. It also contains many questions that are asking for the obvious: ‘are you realy realy realy sure you lsot your product key, are yo usure you looked everywhere?? did you even look under your matrass, in your cupboard and in the broomcloset?? no, then go check it and tell us how your broomcloset looks like from the inside’ Ok I maybe a lil bit over the top here, but you got my point, The list is irritating and as said it changes.
The bottom line is that they will give you back access if you are the rightfull owner (but not a replacement productkey).
Arise, opressed of Tyria!
