Windows activation offline

Hi Ayesha,

Please press Windows key + R, type SLUI 4, and press Enter. Follow the on-screen instructions to access the Activate by phone option.

If phone activation is not available in your region, you may be redirected to the Microsoft Product Activation Portal or prompted to contact Microsoft Activation Support directly.

Please note that a Confirmation ID can only be issued by Microsoft after verifying a valid Installation ID. Community members, forum moderators, and chat agents do not have access to activation systems and cannot generate or provide Confirmation IDs.

If you have a valid 63‑digit Installation ID and require offline activation, you will need to contact Microsoft Activation Support so they can verify the license and issue a Confirmation ID if eligible.

For more details, please refer to the official Microsoft documentation below:
Product activation for Windows – online & support telephone numbers : https://support.microsoft.com/en-us/windows/product-activation-for-windows-online-support-telephone-numbers-35f6a805-1259-88b4-f5e9-b52cccef91a0

I hope the information above is helpful. If you have any further questions, please feel free to let us know.

Best regards,
Nam Bui
