Millions of computer users are approaching a critical deadline. Microsoft will officially end support for Windows 10 on Tuesday, 14 October. After that date, PCs will no longer receive vital security updates, leaving them more exposed to cyberattacks and malware. Without regular patches, older systems will face higher risks. Microsoft urges users to upgrade to Windows 11 for free, but many devices cannot meet the new system’s hardware requirements. Nathan Proctor, senior director at US consumer group PIRG, warns that ending support could harm both users and the environment.
Millions still rely on Windows 10
Windows remains the world’s most widely used 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 continue to rely on Windows 10. A survey found roughly a quarter of users plan to continue using it even after support ends, while about one in seven intend to buy a new computer.
Consumer advocates have criticised Microsoft’s move, 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.
How to protect your device
Microsoft gives personal users two main options. They can upgrade to Windows 11 or sign up 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 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 offers ESU, which provides essential security patches until October 2026. ESU does not include technical support or new features. 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 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.
What will change after support ends
Since its 2015 launch, Windows 10 has received constant updates to improve security, fix bugs, and add features. Microsoft now wants users to move to Windows 11, but the new system has stricter hardware requirements. It also requires a Microsoft account for full functionality. 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 PCs will stop receiving critical security updates. This will leave them more vulnerable to malware, ransomware, and other cyber threats. Without patches, defences will weaken, increasing risk.
Recent cyberattacks have affected major retailers, car manufacturers, and childcare providers. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that companies using unsupported software could face compliance and security problems. Developers may also stop supporting Windows 10, causing apps to lose features or compatibility.
For millions of users, the decision is urgent. Upgrading ensures continued protection and access to features, while staying on Windows 10 increases digital risks every day.
