Knowing what’s coming next is crucial if you’re still using Windows 10. According to Microsoft’s official announcement, Windows 10 support will terminate on October 14, 2025.
Your computer will eventually become more vulnerable to security threats because there won’t be any more security updates or general fixes available after that.

Windows 10 Support Deadlines: Here’s What You Must Know
Regular updates for Windows 10 won’t be available after the deadline. Security patches that shield your system from fresh malware or hacks are part of this.
Given that many older devices might not meet the hardware requirements for a direct upgrade, Microsoft strongly advises moving to Windows 11 before the deadline.
By October 2025, Microsoft originally intended to cease updates for all Office applications running on Windows 10.
However, that is no longer the case. You will now continue to receive app updates and support until October 2028 if you are using Microsoft 365 on Windows 10. The purpose of this extension is to keep users safe while they plan an update.
Additionally, until at least 2028, Windows Defender, the integrated antivirus program, will continue to receive updates for malware definitions.
Support schedules for Office versions that are purchased once, however, differ.
- Up until October 2026, Office 2021 will be compatible with Windows 10.
- Support for Office 2024 will last until October 2029.
Because some pages may still display out-of-date support dates, be sure to consult Microsoft’s official sources.
Extended Security Updates (ESU) is a paid program offered by Microsoft. This enables you to continue receiving important security updates after the 2025 deadline.
Individual users can purchase the ESU plan, which costs $30 per PC for the first year. Support is extended for an additional three years.
However, since not all Windows 10 systems are compatible with the upgrade, Microsoft advises users to switch to a Windows 11-compatible PC rather than depending on ESU.
Windows 11 can be installed on unsupported PCs, but the process is difficult and might not be dependable or safe for the typical user.
Support for Windows 10 is quickly coming to an end. The primary Windows 10 support deadlines remain unchanged, even though Microsoft is extending the time for Microsoft 365 users and antivirus updates.
Avoid waiting until the last minute. For extended app support, choose now whether to upgrade your computer, sign up for ESU, or move to Microsoft 365.
