A major deadline is fast approaching for computer users worldwide. Microsoft will officially end support for Windows 10 on Tuesday, 14 October. After that date, PCs will stop receiving crucial security updates, making them more vulnerable to hackers and malware. Without regular patches, older systems will become easy targets for attacks. Microsoft urges users to upgrade to Windows 11 for free, but many devices will not meet the newer system’s hardware requirements. Nathan Proctor, senior director at US consumer group PIRG, warns that ending support could hurt both consumers and the environment.
Millions still run Windows 10
Windows remains the most widely used computer operating system in the world. Microsoft reports that it runs on more than 1.4 billion devices globally. According to Statcounter, about 43% of these still used Windows 10 in July 2025. In the UK, consumer group Which? estimates that 21 million people continue to rely on Windows 10. A survey revealed that around a quarter of users plan to keep using the system even after support ends, while about one in seven intend to buy a new computer.
Consumer groups have criticised Microsoft’s move, saying it will cause unnecessary waste and expense. “People are tired of devices that stop working or lose support too quickly,” said Proctor. “We deserve technology that lasts,” he added.
How users can stay protected
Microsoft offers two main paths for personal users. They can upgrade to Windows 11 or subscribe to extended security updates (ESU) for an extra 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 purchase new hardware, even if their current PCs still perform well.
For those unable or unwilling 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 installing the latest version of Windows 10, 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.
What happens after support ends
Since its release in 2015, Windows 10 has received consistent updates to fix bugs, improve performance, and enhance security. Microsoft now wants users to transition to Windows 11, but the new system demands stronger hardware and a Microsoft account for full functionality. Even those using ESU must log in with a Microsoft account. Some users have expressed privacy concerns about this rule.
The danger of doing nothing
After support ends, Windows 10 computers will stop receiving critical security updates. This will leave them increasingly vulnerable to malware, ransomware, and other online threats. Without patches, defences weaken over time, exposing users to higher risks.
Recent cyberattacks have targeted major retailers, car manufacturers, and childcare providers. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that businesses relying on unsupported software may face compliance and security challenges. Developers may also stop supporting Windows 10, causing apps to lose functionality or compatibility.
For millions of users, the choice is clear. Upgrading ensures continued safety and reliability, while staying on Windows 10 means facing a growing wave of digital threats.
