Furthermore, OA 3.0 introduced the Digital Product ID (DPID). The operating system generates a hardware hash based on the system's components and the unique BIOS key, which is then sent to Microsoft servers for validation. This shift moved the trust anchor from a static, locally readable BIOS table to a dynamic, server-side verification process.

During the boot process, the Windows Software Licensing Service (SLS) checks for the presence of a valid SLIC table in the ACPI tables. It then compares the information in the SLIC table against the installed OEM certificate and the OEM product key. If all three components match and verify cryptographically, Windows activates automatically without contacting Microsoft servers. This process relies on the assumption that the BIOS firmware is a trusted environment that cannot be easily altered by the user. Since 2015, Microsoft has included anti-piracy mechanisms in
