Millions of computer users are approaching a major turning point. Microsoft will officially end support for Windows 10 on Tuesday, 14 October. After that date, the system will no longer receive vital security updates, leaving PCs increasingly vulnerable to hackers and malware. Without new patches, older devices will become easier to attack. Microsoft urges users to upgrade to Windows 11 for free, but many computers cannot meet the required hardware standards. Nathan Proctor, senior director at US consumer group PIRG, warns that ending support could harm both consumers and the environment.
Millions still depend on Windows 10
Windows remains the most widely used operating system worldwide. Microsoft says it runs on over 1.4 billion devices. Statcounter reports that around 43% of them were still using Windows 10 in July 2025. In the UK, consumer organisation Which? estimates that 21 million people continue to rely on it. A recent survey found that one in four users plan to keep using Windows 10 even after support ends. About one in seven said they would buy a new computer instead.
Consumer advocates have criticised Microsoft’s decision, calling it costly and environmentally wasteful. “People are tired of short-lived devices that lose software support too soon,” said Proctor. “We deserve technology that lasts,” he added.
What users can do now
Microsoft offers two options for personal users. They can upgrade to Windows 11 or register 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 devices can upgrade to Windows 11 for free. However, many will have to purchase new hardware, even if their current PCs still perform well.
For those who cannot or do not wish to upgrade, Microsoft provides ESU, which offers essential security patches until October 2026. The ESU does not include new features or technical support. Users in the European Economic Area can access it 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 location.
What changes after support ends
Since its 2015 release, Windows 10 has received regular updates that improved security, fixed bugs, and introduced new features. Microsoft now wants users to switch to Windows 11, but the newer system comes with stricter hardware demands. It also requires a Microsoft account for full access. Even the ESU programme needs one. Some users have voiced privacy concerns about this requirement.
The risks of staying with Windows 10
Once support ends, Windows 10 PCs will stop receiving critical security updates. This will make them more vulnerable to ransomware, viruses, and other cyber threats. Without updates, their defences will weaken over time.
Recent cyberattacks have affected major retailers, car manufacturers, and childcare providers. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that companies using unsupported software could face compliance and security problems. Developers may also stop supporting Windows 10, leading to fewer updates and app issues.
For millions of users, the clock is ticking. Upgrading ensures safety and stability, while staying on Windows 10 could mean facing greater digital risks every day.
