Microsoft is officially ending no-charge support for Windows 10 today, October 14, 2025. After this date, Microsoft will not release any no-charge security, reliability, or compatibility updates or patches for Windows 10, nor will they provide support to solve issues with this eight-year-old operating system. Remaining users of Windows 10 are strongly encouraged to migrate to a supported version of Windows 11 as soon as possible. This migration could potentially require the purchase of new hardware that is capable of running Windows 11.
Information Systems & Computing (ISC) is providing a one-time, one-year extension to Windows 10 security updates for Penn’s institutionally-owned and managed systems. More information on this effort is here. As of mid-October 2025, the University’s installed base of Windows 10 is about 13% of all Windows systems.
