Microsoft will stop supporting Office apps on Windows 10 this year. Also it really wants you to upgrade to Windows 11.

According to a Microsoft blog post, the company will end support for Microsoft 365 apps on Windows 10 on Oct. 14, 2025. That includes Office apps: Microsoft Teams, Word, Excel, PowerPoint, Outlook, and OneDrive.

But that doesn't mean your apps will stop working when the deadline hits. A Microsoft support page spotted by The Verge said "the applications will continue to function as before. However, we strongly recommend upgrading to Windows 11 to avoid performance and reliability issues over time." So because Microsoft will no longer maintain them after the cutoff date, the apps will gradually get buggier.

Microsoft has been pushing hard for PC users to upgrade to Windows 11. The latest operating system has been out since 2021, but the vast majority of users still use its predecessor. According to Statcounter, 63 percent still run Windows 10, while only 34 percent have upgraded to Windows 11. The low adoption rate is largely due to Windows 11 system requirements like a TPM (Trusted Platform Module) that PC users are unable or unwilling to comply with.

Nonetheless, Microsoft has made it clear that upgrading is the only option. Especially since Windows 11 has Copilot AI features that the company has spent the last few years developing and aggressively promoting.

In October 2024, Microsoft first announced the end of Windows 10 support, and is calling 2025, "the year of the Windows 11 PC refresh," instead of advancing the OS timeline with Windows 12.
