Beginning October 14, 2025, Microsoft will cease support for most versions of Windows 10, prompting the Ohio University Office of Information Technology (OIT) to restrict access for OHIO-managed systems running unsupported versions. This affects all versions of Windows 10 prior to version 22H2, which is eligible for the Extended Security Updates (ESU) program. The ESU program provides paid access to critical security updates for older operating systems after official support ends. OIT plans to restrict access for all Windows 10 systems, including those with ESU, by October 2026 and no later than October 2028, when the ESU program concludes.
