A major shift is coming for computer users worldwide. Microsoft will officially end support for Windows 10 on Tuesday, 14 October. After that date, millions of PCs will no longer receive critical security updates, leaving them vulnerable to cyberattacks. Without these updates, hackers and malware will have an easier path to exploit system weaknesses. Microsoft urges users to upgrade to Windows 11 for free, but many older devices cannot meet the hardware requirements. Nathan Proctor, senior director at the US consumer group PIRG, warns the change could impact both consumers and the environment.
Millions continue to use Windows 10
Windows remains the world’s most popular operating system. Microsoft reports it runs on over 1.4 billion devices globally. Statcounter data shows that around 43% of these devices were still running Windows 10 in July 2025. In the UK, consumer group Which? estimates 21 million people still rely on the system. A survey found roughly a quarter of users plan to continue using Windows 10 even after official support ends. About one in seven said they plan to buy a new computer instead.
Consumer groups have criticised Microsoft’s decision, calling it costly and wasteful. “People are frustrated with devices that break or lose support too quickly,” said Proctor. “We deserve technology that lasts,” he added.
Steps users can take
Microsoft offers two main options for personal users. They can upgrade to Windows 11 or register for extended security updates (ESU) for one more year. Both options are available in the “Privacy and Security” section of system settings. Users with compatible devices can upgrade to Windows 11 for free. However, many will need to buy new hardware, even if their current PCs still work well.
For those who cannot or do not want to upgrade, Microsoft provides ESU, which delivers essential security patches until October 2026. ESU does not include new features or technical support. Users in the European Economic Area can register for free. Others can qualify by updating to the latest Windows 10 version, having a Microsoft account, and backing up their device settings.
If users do not meet these requirements, they must pay $30 (£22) or use 1,000 Microsoft Rewards points to access ESU. Businesses using Windows 10 will pay $61 per device, depending on location.
Changes after support ends
Since its launch in 2015, Windows 10 has received regular updates for security, performance, and new features. Microsoft now encourages users to move to Windows 11, but older PCs may not meet the stricter hardware standards. The new system also requires a Microsoft account for full access. Even extending Windows 10 through ESU requires one. Some users have raised privacy concerns about this requirement.
Risks of staying on Windows 10
After support ends, Windows 10 computers will stop receiving critical security updates. This will leave them more vulnerable to malware, ransomware, and other online threats. Over time, the lack of updates will weaken protection and increase risk.
Recent cyberattacks have targeted major retailers, car manufacturers, and childcare organisations. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that companies using unsupported software may face compliance and security issues. Developers may also stop supporting Windows 10, causing apps to lose features or compatibility.
For millions of users, the choice is clear. Upgrading ensures ongoing protection and access to features, while staying on Windows 10 exposes systems to growing digital risks.
