Windows 8.1 reached end of support (EOS) on January 10, 2023, at which point technical assistance and software updates are no longer provided. If you have devices running Windows 8.1, we recommend upgrading them to a more current, in-service, and supported Windows release.

For more information, see Windows 8.1 support will end on January 10, 2023.
We recommend updating to a later version of Windows.
