Hello,
About how to activate Windows by phone, please follow these steps:
- Select the Start button, enter PC settings, and then select PC settings from the list of results.
- Select Activate Windows, and then select Contact customer support for help. You may be asked for an admin password or to confirm your choice.
- Select your location (or the location nearest to you) from the drop-down list, and then select Next.
- Call one of the available phone numbers listed. An automated system will guide you through the activation process.
However, support for Windows 8.1 ended on January 10, 2023. We recommend you move to a Windows 11 PC to continue to receive security updates from Microsoft.
Best Regards,
Hania Lian
