Millions in UK at risk of cyber-attacks as Windows 10 ends updates, Which? finds

Survey shows one in four users intend to keep using system as it is phased out, despite increased virus and malware risk

About 5 million British computer users risk becoming vulnerable to cyber-attacks and scams after Microsoft next week stops updating its decade-old Windows 10 system, consumer campaigners have warned.

One in four of an estimated 21 million UK people using a device that runs the Windows 10 software intend to continue using it after updates cease and so will be at risk of online security breaches including malware and viruses, according to a survey by Which? More than a third of those who are not planning to take action and therefore risk becoming vulnerable are people aged over 55.
