For offline (standalone) Windows and Office activation, the traditional automated phone workflow has been replaced by the Product Activation Portal. Offline activation is still supported, but the human operator must now use the online portal instead of the old telephone automation.
Key points for the new process:
- Use the Product Activation Portal
- Go to the Product Activation Portal: Product Activation Portal.
- A human operator completes the CAPTCHA and signs in with one of the supported account types (personal Microsoft account, work or school account, Microsoft Entra ID account, or Azure Government tenant account).
- The sign-in account is only for secure portal access and is not tied to the product license.
- Use Installation IDs from offline machines
- For standalone, non‑internet‑connected devices, continue to generate the Installation ID on each device as before (using the Windows activation UI or
SLUI 04where applicable). - Instead of entering the Installation ID into an automated phone system, the operator enters it into the Product Activation Portal.
- The portal returns the Confirmation ID, which can then be typed back into the offline device to complete activation.
- For standalone, non‑internet‑connected devices, continue to generate the Installation ID on each device as before (using the Windows activation UI or
- Windows and Office volume scenarios
- For enterprise/volume scenarios (for example, KMS host keys used with Active Directory‑based activation), the KMS host key/CSVLK itself must now be activated online or by using the Product Activation Portal, not the legacy phone automation.
- Once the KMS host is activated, offline domain‑joined clients can continue to activate via Active Directory‑based activation as before.
- Existing offline environments
- Offline activation capabilities remain supported; there is no requirement to connect the standalone machines to the internet.
- The change is only in how the operator obtains the Confirmation ID (portal instead of automated phone system).
If activation still fails after using the Product Activation Portal with the Installation IDs, contact Microsoft support directly for the specific keys or products in use.
