Technical Info on WPA
For those of you who are interested(or paranoid,) here's information from Microsoft on the WPA process, including how much has to require re-authorization.
http://www.microsoft.com/piracy/basi...bulletin.do c From that, here's the list of what it uses to generate your hardware ID code: Display Adaptor (5 bits) SCSI Adaptor (5 bits) IDE Adaptor (4 bits) Network Adaptor MAC Address (10 bits) RAM Amount Range (3 bits) Processor type (3 bits) Processor Serial # (6 bits) Hard Drive Device (7 bits) Hard Drive Volume Serial # (10 bits) CD-ROM/CD-RW/DVD-ROM (7 bits) "Dockable" (1 bit) Algorithm Version Used (3 bits) Another thing to note is that in cases of things like the processor serial #, the actual hash code generated is 128 bits in length, but only 6 of those are used. Which means that out of the 100 million or more PCs sold last year, only 64 keys could be generated(privacy issues solved)...but back to WPA Of that list up above, if you haven't changed your network adaptor(if you even have one), you can change up to 6 of them without having to reactivate. If your network adaptor changes, then you can change up to 4 without requiring reactivation. Also, just one last note, in a direct quote from that document, "the Microsoft activation clearinghouse system will automatically allow activation to occur over the Internet four times in one year on substantially different hardware." Just some info I found that I decided to pass along... |
