A major tech deadline is approaching for millions of computer users. On Tuesday, 14 October, Microsoft will officially end support for Windows 10. After that day, the operating system will no longer receive crucial security updates, leaving PCs increasingly open to cyberattacks. Without patches, hackers can exploit vulnerabilities more easily. Microsoft urges users to upgrade to Windows 11 for free, but many older devices will not meet the system’s stricter requirements. Nathan Proctor, senior director at US consumer group PIRG, warns that ending support could harm consumers and worsen electronic waste.
Millions still using Windows 10 worldwide
Windows remains the most widely used computer operating system globally. Microsoft says it runs on over 1.4 billion devices. According to Statcounter, 43% of them still used Windows 10 as of July 2025. In the UK, consumer group Which? estimates that 21 million people continue to rely on Windows 10. A recent survey showed that one in four users plan to keep using the system even after support ends, while one in seven intend to buy a new computer.
Consumer organisations have criticised Microsoft’s decision, calling it wasteful and costly. “People are tired of short-lived devices that lose support too fast,” said Proctor. “We deserve technology that lasts,” he added.
What users should do next
Microsoft offers two main paths for personal users. They can upgrade to Windows 11 or register for extended security updates (ESU) for another year. Both options are available under “Privacy and Security” in system settings. Eligible users can upgrade for free, but many will need to buy new devices even if their current PCs still work well.
For users unable or unwilling to upgrade, ESU provides essential security updates until October 2026. The service does not include technical support or new features. 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 settings.
If users do not meet these requirements, they must pay $30 (£22) or use 1,000 Microsoft Rewards points for ESU. For businesses, the cost is $61 per device, depending on location.
What will change after support ends
Since its 2015 release, Windows 10 has received regular updates to improve performance and security. Now, Microsoft encourages users to switch to Windows 11, which requires newer hardware and a Microsoft account for full access. Even ESU subscribers must use a Microsoft account. Some users have voiced concerns about this, citing privacy issues.
Why it’s risky to stay on Windows 10
After 14 October, Microsoft will stop sending vital security patches to Windows 10 computers. This means increased exposure to malware, ransomware, and other online threats. Without updates, protection will weaken over time.
Recent cyberattacks have targeted retailers, carmakers, and childcare providers. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that companies using unsupported software could face compliance issues and higher risks of breaches. Developers may also stop updating their apps for Windows 10, reducing functionality.
For millions of users, the message is clear. Upgrading ensures safety and long-term performance, while staying on Windows 10 means facing growing digital dangers.
