Windows 10 has reached end of support (EOS) today, October 14, 2025, but the operating system is still running on hundreds of millions of devices.
With Windows 10 reaching EOS, Microsoft will no longer provide free software updates, technical support, or security patches.
PCs running Windows 10 will continue to work, but they will become increasingly vulnerable to malware and other cyberattacks as new threats emerge and no patches are released.
For users who cannot immediately upgrade to Windows 11, Microsoft has launched the Extended Security Updates (ESU) program.
In order to enroll into the ESU program and get important security updates until October 13, 2026, consumers will be charged $30, while commercial organizations will have to pay $61 per device. The price will double each year for organizations that want ESU for up to three years.

In addition, Microsoft announced recently that ESU will be free for users in the European Economic Area (EEA).

Statcounter data for September 2025 showed that while Windows 11 had been running on nearly half of desktop machines, Windows 10 was also still installed on just over 40% of devices.
An analysis conducted by remote access and support giant TeamViewer showed that more than 40% of global endpoints that recently received support via its software had been running Windows 10. TeamViewer’s analysis — based on 250 million remote support connections — showed that Windows 11 had been running on 47% of devices.
Cybersecurity firm Kaspersky has also analyzed data collected from its customers and found that only 33% have upgraded to Windows 11 and 53% are still using Windows 10. Moreover, in the case of corporate users, Windows 10 is still present on nearly 60% of systems.
