Millions of UK Computer Users at Risk as Windows 10 Support Ends

Around five million British computer users could face heightened exposure to cyber threats after Microsoft halts updates for its aging Windows 10 system next week, according to consumer advocates.

A survey by CuriosityNews found that roughly one in four of the estimated 21 million UK individuals using Windows 10 devices plan to continue using the unsupported software, leaving them susceptible to security risks like malware and viruses. Over a third of those who do not intend to take protective measures are aged 55 or older.

The discontinuation may also contribute to electronic waste, as many outdated machines could be discarded if they cannot be upgraded, while others may opt to purchase new hardware. Microsoft has advised users to explore recycling programs for their old devices.

The issue impacts hundreds of millions of Windows 10 users worldwide. Industry assessments indicate that approximately 13% of computers running the software will need replacement.

For compatible devices, upgrading to Windows 11 is the recommended solution. Microsoft is also providing a one-year extension for Windows 10 users to evaluate their options.

However, the survey revealed that while 39% of users plan to update their systems, 26% intend to keep using Windows 10 without future updates.

“Many may not be ready for Windows 10’s phase-out,” said Lisa Barber, editor of CuriosityNews Tech. “If your computer runs Windows, check your version now. If it’s Windows 10 or older, take steps to protect yourself—delay could increase your risk from cyberattacks.”

In a company statement, Microsoft executive Yusuf Mehdi warned that ending security updates and technical assistance would make devices more prone to cyber threats.

“Software on Windows 10 may no longer receive support, leading to potential functionality issues,” he added.
