Key Takeaways
- Windows 10 support ends on October 14, 2025, leaving millions vulnerable to cyber attacks

Microsoft is ending all security support for Windows 10 on October 14, exposing hundreds of millions of users to potential cyber attacks and data theft. The tech giant will stop providing critical security updates for one of its most popular operating systems, despite over 40% of Windows users still relying on it.
Security experts are urging immediate action, warning that continued use of Windows 10 creates prime conditions for attackers to exploit unpatched vulnerabilities. The situation echoes past incidents like the WannaCry attack that crippled NHS systems.
UK Impact and User Intentions
Approximately 5 million people in Britain continue using Windows 10 devices, with a recent Which? survey revealing that a quarter plan to keep using the unsupported software. Security advisors recommend all users create full data backups regardless of their upgrade plans.
Devices running Windows 10 after the deadline will likely experience performance degradation and decreased functionality alongside security risks.
Expert Warnings and Solutions
Cyber security advisor Matt Balderstone from CyberArk emphasized the urgency: “Once Windows 10 reaches end-of-life, the absence of security updates will leave millions of machines exposed to future vulnerabilities that will never be patched.”
He added that in today’s high-risk cyber environment, “one Windows 10 machine is now too many” for both consumers and businesses.
Eligible device owners can upgrade to Windows 11 at no cost or enroll in Microsoft’s Extended Security Updates program. Those who miss the deadline should be particularly cautious about suspicious communications.
Scam Alert for Holdouts
Luis Corrons, security expert at Avast, noted that end of support creates opportunities for scammers: “People may see fake pop-ups, upgrade offers or even get phone calls pretending to be from Microsoft.”
He described the situation as “the end of free safety nets” that attackers are prepared to exploit through unpatched system vulnerabilities.
