A major shift is coming for millions of computer users around the world. Microsoft will stop supporting its Windows 10 operating system after Tuesday, 14 October. This move could leave many computers exposed to security threats. Without regular security updates, devices will become more vulnerable to attacks and malware. Microsoft encourages users to upgrade to Windows 11 for free, but not every computer can handle the new system. Nathan Proctor, senior director at US consumer group PIRG, warns that ending Windows 10 support could be a disaster for both users and the environment.
Who will feel the impact
Windows remains the world’s most popular operating system, used on over 1.4 billion devices worldwide, according to Microsoft. In July 2025, around 43% of those still ran on Windows 10, data from Statcounter shows. In the UK, consumer organisation Which? estimates about 21 million people still use Windows 10. A recent survey by the group found that about a quarter of users plan to keep using Windows 10 even after official support ends. One in seven users say they intend to buy a new computer instead.
Consumer advocates have criticised the end of support, arguing it will push unnecessary spending and create more electronic waste. “People are tired of short-lived devices that can’t be repaired or lose software support,” said Proctor, who campaigns for the right to repair. “We deserve technology that lasts,” he added.
What users need to do now
Microsoft offers two main options for personal users. They can either upgrade to Windows 11 or subscribe to extended security updates for one more year. Both choices can be managed through the “Privacy and Security” section in system settings. Eligible users can move to Windows 11 for free, but many people will need to buy a new computer even if their current one works perfectly well.
For those unable or unwilling to upgrade, Microsoft will continue providing key security updates until October 2026 through the Extended Security Updates (ESU) programme. However, ESU does not include technical support or new features. People living in the European Economic Area can register to receive it for free. Others can also get it free by updating to the latest Windows 10 version, having a Microsoft account, and backing up their PC settings.
If users don’t meet those conditions, they must pay $30 (£22) or use 1,000 Microsoft Rewards points for access. For businesses using Windows 10, the cost rises to $61 per device, depending on location.
What exactly will change
Since launching in 2015, Windows 10 has received frequent updates to fix bugs, improve performance, and enhance security. Microsoft now wants users to switch to Windows 11, but some older PCs cannot run it due to stricter hardware requirements. The company is also making it harder to use Windows 11 without a Microsoft account. Ironically, those who wish to extend their Windows 10 system’s life will also need one. Some users are unhappy about this, citing privacy concerns over linking their accounts.
The risks of doing nothing
After support ends, Windows 10 computers will no longer receive crucial security fixes. This gap will make devices easier targets for hackers, viruses, and malicious software. Users will lose protection against new online threats as updates stop.
Recent months have seen major cyber-attacks affecting retailers, car manufacturers, and even nursery chains. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that companies may struggle to stay compliant with regulations when using unsupported software. Other applications could also lose features as developers move on to newer systems.
For millions of users, the clock is ticking. Staying on Windows 10 will soon mean choosing between convenience and security.
