ReferralId specifies the identity of OEMs participating in the Windows Anytime Upgrade reward program. Referral payments are used to reward the party that conducts a promotional activity resulting in the purchase and successful activation of a digital license.

OEMs enter the referral ID for all computers that are enabled for Windows Anytime Update.

OEMs participating in the Windows Anytime Upgrade reward program are assigned a six-digit referral ID by the Referral Tracking System (RTS) after signing a Windows Anytime Upgrade Referral Agreement.

The referral ID and the partial Product Identifier (PID) are included in the information that is passed from Windows Vista to the activation server during activation. The PID provides a unique digital fingerprint to a Microsoft product license. This digital fingerprint is used to manage and to track support effectively and to detect and to deter product piracy. Because only the first six digits are used, rather than the complete 20-digit value, only a partial PID is needed.

The RTS uses the referral ID to identify the OEM participating in the Windows Anytime Upgrade program and the associated partial PID to determine the product for the qualifying reward.
