New versions of Microsoft Office will no longer be released for Windows 10
Thus, Microsoft 365 services, including Outlook, will no longer be supported on this operating system. Support articles on the Microsoft website specify that some Microsoft 365 features may stop working fully if the user does not update to a newer version of the operating system.
However, users will be able to continue using Microsoft 365 on Windows 10 without updates. However, to avoid problems with performance, security, and functionality, Microsoft recommends upgrading to Windows 11 before October 14, 2025.
In addition, on October 14, 2025, support for the Windows 10 operating system will end. For users who are not ready to switch to Windows 11 or whose computers are incompatible with the new OS, a paid annual subscription with security updates for the old operating system will be available.
The cost of extended security updates (ESU) will be $61 per year per device. In the second year, the price will double to $122, and in the third year, it will triple to $244.
