Millions of computer users are approaching a critical deadline. Microsoft will officially end support for Windows 10 on Tuesday, 14 October. After that date, PCs will no longer receive essential security updates, leaving them vulnerable to cyberattacks. Without updates, hackers and malware can more easily exploit system weaknesses. Microsoft urges users to upgrade to Windows 11 for free, though many older devices will not meet the hardware requirements. Nathan Proctor, senior director at US consumer group PIRG, warns that ending support could affect both consumers and the environment.
Millions still rely on Windows 10
Windows remains the most widely used operating system worldwide. Microsoft reports it runs on over 1.4 billion devices globally. According to Statcounter, around 43% of these devices still used Windows 10 in July 2025. In the UK, consumer group Which? estimates that 21 million people continue to rely on the system. A survey revealed that roughly a quarter of users plan to continue using Windows 10 even after support ends. About one in seven said they intend to buy a new computer.
Consumer groups have criticised Microsoft’s decision, calling it costly and wasteful. “People are frustrated with devices that break or lose support too quickly,” said Proctor. “We deserve technology that lasts,” he added.
What users can do to stay secure
Microsoft offers two main options for personal users. They can upgrade to Windows 11 or subscribe to extended security updates (ESU) for another year. Both options are accessible through the “Privacy and Security” section in settings. Users with compatible devices can upgrade to Windows 11 for free. However, many will need to purchase new hardware, even if their current PCs still function well.
For those unable or unwilling to upgrade, Microsoft provides ESU, which delivers essential security patches 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 Windows 10 version, creating a Microsoft account, and backing up their device settings.
If these steps are not completed, users 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.
How Windows 10 will change
Since its release in 2015, Windows 10 has received constant updates to fix bugs, improve security, and add features. Microsoft now wants users to shift to Windows 11, but the newer system has stricter hardware requirements. It also requires a Microsoft account for full functionality. Even extending Windows 10 via ESU requires one. Some users have raised privacy concerns about this requirement.
The risks of staying on Windows 10
Once support ends, Windows 10 devices will stop receiving critical security updates. This leaves them more vulnerable to malware, ransomware, and other online threats. Without patches, defences weaken over time, increasing risk.
Recent cyberattacks have targeted major retailers, car manufacturers, and childcare providers. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that businesses using unsupported software may face compliance and security issues. Developers may also stop supporting Windows 10, causing apps to lose features or compatibility.
For millions of users, the decision is urgent. Upgrading ensures protection and continued functionality, while remaining on Windows 10 brings growing digital risks.
