Microsoft has announced that starting October 14, 2025, it will no longer support its Office app, now branded as Microsoft 365 apps, on devices running Windows 10. This decision aligns with the official end of support for Windows 10 itself, signalling a strong push from the tech giant for users to adopt Windows 11.
While Microsoft 365 apps will remain functional beyond the cutoff date, the company has cautioned that users may encounter performance and reliability issues over time. A support document updated in December 2024 elaborates on potential risks, emphasising that although the apps will not cease to operate, the lack of updates and fixes could degrade user experience, reports The Verge.
The announcement comes as Microsoft has intensified efforts to transition users to Windows 11.
“Microsoft 365 Apps will no longer be supported after October 14, 2025, on Windows 10 devices,” Microsoft said. “To use Microsoft 365 Applications on your device, you will need to upgrade to Windows 11.”

Despite these efforts, Windows 11’s adoption rates remain sluggish. Many users cannot upgrade due to Microsoft’s stringent hardware requirements, including the mandatory Trusted Platform Module (TPM) 2.0. The company has reaffirmed that this requirement is ‘non-negotiable,’ effectively ruling out older devices from running Windows 11.
Although the company insists on TPM 2.0 to prevent tampering and cyberattacks, users have found ways to bypass TPM requirements easily.
To expedite the transition, Microsoft has introduced full-screen prompts urging Windows 10 users to upgrade to newer devices compatible with Windows 11. For those who choose to remain on Windows 10, the company offers Extended Security Updates (ESUs) for the first time to individual consumers.
Priced at $30 for an additional year of updates, this option allows users to extend security support through 2026. businesses, on the other hand, can purchase up to three years of ESUs.
