End of Support for Windows 10 — What It Means for Businesses
Starting October 14, 2025, Microsoft will end official support for Windows 10. After that date, there will be no more security updates, new features, or bug fixes, which significantly increases risk for corporate environments.
What’s changing:
-
Windows 10 will continue to run, but without security updates it will be more exposed to cyberattacks and compatibility issues with newer applications.
-
Through the Extended Security Updates (ESU) program, organizations can receive critical security updates until October 13, 2026.
-
In the European Economic Area (including Greece), Microsoft provides free access to ESU for 1 year, provided there is periodic sign-in to a Microsoft Account.
What remains active:
-
Microsoft Edge and the WebView2 components will continue to receive updates on Windows 10 through 2028.
-
Microsoft 365 apps (Office, Teams, etc.) will remain supported with security updates until October 10, 2028.
Recommended actions for businesses:
-
Infrastructure assessment: Check whether existing systems are compatible with Windows 11 and evaluate cost/benefit for upgrading or replacing hardware.
-
ESU: Where an upgrade can’t happen immediately, enroll systems in the ESU program so they continue receiving critical security updates.
-
Continuous updating: Keep systems and applications on the latest available versions to minimize risk.
-
Backup policy: Implement and regularly test backup procedures to protect critical corporate data.
The end of Windows 10 support is a turning point for every organization. A timely strategy—either migrating to Windows 11 or leveraging ESU as a temporary measure—is crucial for security and business continuity.
