Microsoft continues to create frustration around the end of life of Windows 10. In a confusing communication, the company suggests that Microsoft 365 may no longer work on the system in October 2025.
The end of Windows 10 maintenance is scheduled for October 14, 2025, that is to say in ten months almost to the day. After this deadline, the operating system will no longer receive any updates, neither quality nor security. For people who would like to continue using Windows 10 safely, a paid maintenance extension program will be offered, for a period of one year.
But the end of life of Windows 10 could also have an impact on another flagship product of the company: the Microsoft 365 office suite. As a reminder, this is a subscription plan (with a recurring payment therefore) which provides access to several applications from the Office suite, such as Word, Excel or PowerPoint. And as is often the case, Microsoft communicates in a confusing manner on the consequences of stopping Windows 10 maintenance on the Microsoft 365 office suite.
Microsoft 365: the office suite soon reserved for Windows 11?
‘on the one hand, the company indicates in a blog post from January 14, 2025 that Microsoft 365 apps will stop working on Windows 10 after October 14, 2025. On the other hand, on the official support pagethe company indicates this time that the suite’s applications will continue to function normally on Windows 10 after this date.
Microsoft is just warning of possible stability and performance issues for Microsoft 365 applications on Windows 10 after stopping maintenance of the operating system. We also understand, by reading between the lines, that Microsoft 365 will no longer receive updates on Windows 10 after October 14, 2025.
Contradictory and difficult to read information therefore, unfortunately like Microsoft’s communication and documentation since the release of Windows 11. For customers subscribed to the Microsoft 365 suite on Windows 10, it is impossible to know precisely which foot to dance on , and what attitude to adopt by October 2025.
The only recommendation that we can make at this stage, if you are still using Windows 10 on your PC, is not to renew your subscription to Microsoft 365 for a period beyond October 14, 2025, favoring a monthly subscription rather than annually (even if this is unfortunately more expensive).
For those who have already renewed their subscription beyond the fateful date, and who are still on Windows 10, you will then have to wait to see the real effects of stopping system maintenance on Microsoft 365 applications. Because despite the company’s “alerts”, which are above all barely disguised incentives to upgrade to Windows 11, it is still unlikely that Word, Excel or PowerPoint in the Microsoft 365 version will stop working overnight on Windows 10 after October 14, 2025.
