A major shift is coming for computer users worldwide. On Tuesday, 14 October, Microsoft will officially end support for Windows 10. After that date, the operating system will stop receiving security updates, exposing computers to increased risks from hackers and malware. Without new patches, older machines will be easier to target. Microsoft is encouraging users to upgrade to Windows 11 for free, though many devices cannot meet the newer system’s requirements. Nathan Proctor, senior director at the US consumer group PIRG, warns that the decision could harm both consumers and the environment.
Millions still rely on Windows 10
Windows remains the most used operating system on the planet. Microsoft reports it runs on more than 1.4 billion devices globally. Statcounter data shows that about 43% of those were still running Windows 10 in July 2025. In the UK, consumer organisation Which? estimates that 21 million people still use it. A recent survey found that roughly one in four users plan to continue using Windows 10 even after support ends, while about one in seven intend to buy a new computer.
Consumer advocates argue that Microsoft’s move will push people toward unnecessary purchases and increase electronic waste. “People are tired of devices that lose support too quickly,” said Proctor. “We deserve technology that lasts,” he added.
What users can do to stay protected
Microsoft gives personal users two main choices. They can upgrade to Windows 11 or register for extended security updates (ESU) for another year. Both options are available in the “Privacy and Security” section of system settings. Users with compatible PCs can upgrade to Windows 11 for free. However, many will need to buy new hardware even if their current computers still work properly.
For those who cannot or do not wish to upgrade, Microsoft offers ESU, which provides essential security updates until October 2026. The programme does not include technical support or feature updates. Users in the European Economic Area can sign up for free. Others can qualify by updating to the latest version of Windows 10, 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 their region.
What changes after support ends
Since its launch in 2015, Windows 10 has received frequent updates to improve performance, fix bugs, and enhance security. Microsoft now wants users to move to Windows 11, but the newer system demands stronger hardware and a Microsoft account for full access. Even ESU subscribers must use a Microsoft account. Some users have raised privacy concerns about this rule.
The growing risk of staying on Windows 10
After 14 October, Windows 10 will no longer receive critical security updates. That means systems will become more exposed to cyber threats such as malware, ransomware, and viruses. Without updates, defences will weaken over time.
Recent cyberattacks have affected retailers, car manufacturers, and childcare providers. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that businesses using unsupported software could face compliance issues and higher security risks. Developers may also stop supporting Windows 10, which could reduce app functionality.
For millions of users, the choice is urgent. Upgrading ensures continued protection and reliability, while staying on Windows 10 increases the danger of falling victim to digital threats.
