Windows 10 and Microsoft 365: The Truth About Support Deadlines

Windows 10 users have been misled by a recurring rumor. The falsehood is that Microsoft will stop supporting Microsoft 365 apps on Windows 10 after October 14, 2025. This is not true. The confusion began with a misleading post by a junior employee. This post was quickly removed, but the damage was done. The post suggested that users would need to upgrade to Windows 11 to keep using Microsoft 365 apps. This was not an official announcement. A Microsoft spokesperson clarified that the information was inaccurate. Microsoft's official stance is clear. Support for Windows 10 will end on October 14, 2025. After this date, Microsoft 365 apps will still work on Windows 10. However, users are encouraged to upgrade to Windows 11 to avoid potential issues. Microsoft will continue to provide security updates for Microsoft 365 apps on Windows 10 for three years after the end of support. This is to ensure security during the transition to Windows 11. The recent buzz is due to a new page on Microsoft's documentation site. This page states that Microsoft will provide security updates for Microsoft 365 apps on Windows 10 until October 10, 2028. This is not a surprise. It matches the extended security updates available to enterprise customers. It's important to understand what "won't be supported" means. It means Microsoft will no longer test new releases on Windows 10. They will still provide security updates. Enterprise customers can still open support cases, but there are limitations. If an issue only occurs on Windows 10, support will ask the customer to move to Windows 11. If the customer can't upgrade, support will provide limited assistance. Consumers using Personal and Family editions of Microsoft 365 will still get security updates. However, they won't get much help if they call support.
