Millions of computer users face a major deadline. Microsoft will officially end support for Windows 10 on Tuesday, 14 October. After that, PCs will no longer receive critical security updates, leaving them vulnerable to hackers and malware. Without ongoing patches, older systems will become easier targets. 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 the change could have serious consequences for both users and the environment.
Millions still rely on Windows 10
Windows remains the world’s most widely used operating system. Microsoft reports it powers over 1.4 billion devices globally. Statcounter data shows around 43% of those devices were still running Windows 10 in July 2025. In the UK, consumer group Which? estimates 21 million people continue to use Windows 10. A survey found that about a quarter of users plan to keep using it even after support ends, while roughly 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 users can stay protected
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 settings. Users with compatible devices can upgrade for free, but many will need to purchase new hardware, even if their current PCs still work well.
For those unable or unwilling to upgrade, Microsoft provides ESU, which delivers 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, creating a Microsoft account, and backing up their settings.
If these requirements are not met, users 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 release in 2015, Windows 10 has received regular 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 condition.
Risks of staying on Windows 10
After support ends, Windows 10 computers will stop receiving critical security updates. This will make them more vulnerable to malware, ransomware, and other online threats. Without updates, defences will weaken over time.
Recent cyberattacks have targeted major retailers, car manufacturers, and childcare providers. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that businesses using unsupported software may face compliance and security risks. Developers may also stop supporting Windows 10, causing apps to lose features or compatibility.
For millions of users, the choice is clear. Upgrading ensures continued protection and access to features, while staying on Windows 10 carries increasing risk every day.
