The product ID (nine bytes) and hardware hash (eight bytes) are used by Microsoft to process the phone activation request.

Online activation over the internet can be accomplished automatically or manually.  During setup the user can select automatic activation, which will result in automatic activation three days after running setup.  If the user chooses manual activation, then at some point over the next 30 days, the user will need to activate their system by either responding to one of the activation prompts or by invoking the product activation wizard.   The product id information sent to the server is the same as in Phone Activation. But the hardware Id sent during online activation is different. We collect 2 bytes of hash information from all the hardware instances that are in the table above. Again these 2 bytes of information will not uniquely identify a customer. It is to differentiate between different hardware devices. These two values (product id and hardware id (long) are sent along with request header information directly through secure sockets (SSL in HTTP) to the Microsoft activation system in a binary format. There are three communications made to complete Internet activation: 网安官方站

  1. Handshake request:  Contains product ID, hardware hash, and request header data such as request ID (for linking the handshake, request, and acknowledgement) and activation technology version. 262 bytes total. 
  2. License request:  Contains product ID, hardware hash, and customer data structure for holding voluntary registration information if provided. If registration is skipped, this structure is empty.  Also contains request header data such as request ID and the PKCS10 digital certificate request structure.  The PKCS10 structure can vary slightly based on the inclusion of voluntary registration information; about 2763 to 3000 bytes total.
  3. Acknowledgement request   Contains certificate ID (returned to user’s machine after license request), issue date, and error code. 126 bytes total.

 

If Internet activation is successful, the activation confirmation is sent directly back to the user’s PC as a digital certificate.  This certificate is digitally signed by Microsoft so that it cannot be altered or counterfeited.  The confirmation packet returned as part of Internet activation is approximately 9 kbytes in size (the digital certificate chain accounts for most of the confirmation data packet size).

If activation is done by telephoning a customer service representative, the product ID and short hardware hash are automatically displayed to the user as the Installation ID; a 50 digit decimal representation.  The data is encoded and has check digits so that it cannot be altered.  Telephone activation is a four step process:
