Microsoft has issued a final warning to hundreds of millions of Windows 10 users worldwide, as support for the operating system ends today, 14 October. The company will no longer provide security updates, feature updates, or technical support, leaving devices vulnerable to cyber threats such as malware and viruses.
According to Microsoft executive Yusuf Mehdi, while Windows 10 devices will continue to function, they will no longer receive regular security updates, making them more susceptible to attacks. Just over 40% of all Windows users still run the old operating system, according to StatCounter Global Stats, which analyses billions of page views across 1.5 million websites.
In the UK, consumer campaigners estimate that around 5 million computer users still use Windows 10. A survey by Which? suggests that a quarter of those intend to keep using it after the deadline. Which? editor Lisa Barber warned that millions may be unprepared, increasing their vulnerability to hackers and scams.
Users may also experience decreased functionality, as applications running on Windows 10 may no longer be supported. Upgrading to Windows 11 is free, but devices must meet minimum hardware requirements. Users can check eligibility by going to Start > Settings > Update & Security > Windows Update and selecting Check for updates.
For those unable to upgrade, Microsoft offers the Windows 10 Consumer Extended Security Updates (ESU) program, which provides critical security updates until 13 October next year. However, it does not include other fixes, feature improvements, or technical support. Users can enroll via the Windows Update section.
