Millions of computer users are facing a major deadline. Microsoft will officially end support for Windows 10 on Tuesday, 14 October. After that date, the system will no longer receive security updates, leaving devices increasingly vulnerable to cyberattacks. Without these updates, hackers could exploit weaknesses more easily. Microsoft is urging users to upgrade to Windows 11 for free, but many older computers do not meet the new system’s hardware requirements. Nathan Proctor, senior director at US consumer group PIRG, warns that ending support could harm consumers and increase electronic waste.
Millions still depend on Windows 10
Windows remains the world’s most widely used operating system. Microsoft says it powers over 1.4 billion devices globally. According to Statcounter, around 43% of those devices were still running Windows 10 in July 2025. In the UK, consumer organisation Which? estimates that 21 million people continue to use Windows 10. A recent survey showed that about one in four users plan to continue using it even after support ends, while one in seven plan to buy a new computer.
Consumer advocates have criticised Microsoft’s decision, calling it costly and damaging to the environment. “People are tired of short-lived devices that lose support too soon,” said Proctor. “We deserve technology that lasts,” he added.
What users can do before the deadline
Microsoft offers two choices for personal users. They can upgrade to Windows 11 or sign up for extended security updates (ESU) for another year. Both options can be found 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 perfectly.
For those who cannot or do not want to upgrade, Microsoft offers ESU, which provides essential security updates 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 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 to access ESU. Businesses using Windows 10 will pay $61 per device, depending on region.
What happens next
Since its 2015 launch, Windows 10 has received regular updates to improve performance and fix security flaws. Microsoft now encourages users to switch to Windows 11, but the newer operating system demands more powerful hardware and requires a Microsoft account for full functionality. Even ESU subscribers must use a Microsoft account. Some users have raised privacy concerns about this rule.
The risk of staying on Windows 10
After 14 October, Microsoft will stop sending crucial security patches and fixes to Windows 10. This will leave computers more exposed to malware, ransomware, and other online threats. Without updates, system defences will weaken over time.
Recent cyberattacks have targeted large retailers, car manufacturers, and even childcare providers. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that businesses using unsupported software could face compliance and security problems. Developers may also stop updating apps for Windows 10, which could limit features and compatibility.
For millions of users, the message is clear. Upgrading means safety and stability, while staying on Windows 10 could bring growing digital risks and long-term costs.
