| Step | What Happens | Why It Matters | |------|--------------|----------------| | | The 25‑character key is parsed by the Office installer and checked against Microsoft’s algorithm (checksum, pattern rules, and product‑line identifiers). | Prevents obviously malformed or counterfeit keys from proceeding. | | 2️⃣ Online Verification | The installer contacts Microsoft’s activation servers, sending the key (encrypted) along with a hash of the machine’s hardware IDs (CPU, motherboard, BIOS, etc.). | Ensures the key isn’t already in use on too many devices, enforcing the license terms. | | 3️⃣ Generation of a Token | If the key is approved, the server returns a digital license token that is cryptographically signed and includes the hardware hash. | The token can only be decrypted on the same machine, binding the license to that hardware profile. | | 4️⃣ Local Storage | Office writes the token to the Windows Registry and to a hidden file in the user profile. | Even if you’re offline later, Office can locally verify that the token matches the current hardware. | | 5️⃣ Re‑activation / Grace Period | If major hardware changes are detected (e.g., motherboard swap), Office prompts you to re‑activate, using the same key or a new one. | Keeps the licensing model flexible for legitimate upgrades while protecting against piracy. |
