Security-only update
REMINDER Windows 8.1 reached end of support on January 10, 2023, at which point technical assistance and software updates is 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. If devices do not meet the technical requirements to run a more current release of Windows, we recommend that you replace the device with one that supports Windows 11.
Microsoft will not be offering an Extended Security Update (ESU) program for Windows 8.1. Continuing to use Windows 8.1 after January 10, 2023 may increase an organization’s exposure to security risks or impact its ability to meet compliance obligations.
For more information, see Windows 8.1 support will end on January 10, 2023.
Windows Embedded 8.1 Industry Enterprise and Pro will reach end of support (EOS) on July 10, 2023. For more information, see Windows Embedded 8.1 Industry.
For Windows Server 2012 R2, the end of support (EOS) date is October 10, 2023. Extended Security Updates (ESUs) will be available for purchase no later than October 2022, but available for installation after the EOS date, October 10, 2023. ESUs will continue for three years, renewable on an annual basis, until the final date on October 13, 2026. For more information, see Windows Server End of Support: Key Dates.
