Support for Windows 10 will end on October 14, 2025. After this date, Microsoft 365 Apps will continue to function on Windows 10 devices, but Microsoft recommends upgrading to Windows 11 to avoid potential performance issues. Microsoft will provide security updates for Microsoft 365 Apps on Windows 10 for three years after the end of support, ending on October 10, 2028. However, Microsoft will not test new releases on Windows 10 after the end-of-support date. Support for Microsoft 365 Apps on Windows 10 will have limitations, including advising upgrades to Windows 11 for issues that do not occur on Windows 11, limited troubleshooting assistance for customers unable to upgrade, and no option to log bugs or request additional updates. These support options do not apply to consumers using the Personal and Family editions of Microsoft 365.
