All that u know about Windows Vista

I know its too late to ask this question....

But as I am a Linux Man, I don't use Windows much...

Well I wanted to download Vista....both 32 bit and 64 bit versions......(coz i have both 32 and 64 bit machines)

Also both RC1 and RC2....

How to get the activation code or serial number what ever u call...
(I don't know much about them as these activation code and serial numbers are not present in LINUX)...

Anyways...

Please give the required Links...
