The stuff you have to go through to post.......
Anyway, there are a lot of reasons for needing your own key. With OEM licensing when you get a key from the manufacturer, the key on the bottom will not be the same. Today I installed Vista on a Toshiba. Before I said bye to the messed up OS on the machine I ran SIW(talk to Uncle Google about that one) to get the Key just in case. I then re-installed Vista on the machine. Used the key on the bottom of the laptop first. Went online to activate and bam " Your key is not valid". Called Microsoft, "sorry sir theres nothing I can do", called good ol' POS Toshiba "Sorry sir nothing we can do, if you'd like we can send you the restore disk for 25 dollars". No thanks, dont want all the junkware you guys stuff down people's throats at a high cost of 25 bucks. Plug in the OEM key that I grabbed with SIW (again do the google search) and Bam!! Activated. Not everyone is trying to do something illegal, and to the Charly Bravos that said it or mentioned it. I just lets everyone else know what you're up to.
Good-day.
