Microsoft warns of a critical security challenge affecting up to 400 million Windows PCs as security updates for Windows 10 approach their end on October 14.
Current data shows Windows 10 still powers 41% of all PCs, down from 46% in September. Approximately 600 million PCs run Windows 10, with up to 400 million unable to upgrade to Windows 11 due to hardware limitations.
Users have two primary options to maintain security: pay $30 for extended support or enroll in Microsoft’s free Extended Security Update (ESU) program, which requires a Microsoft and OneDrive account.
The Public Interest Research Group (PIRG) highlighted the historical context of operating system transitions, noting that when Windows 8 support ended in January 2012016, only 3.7% of users remained on the platform, and by January 2023, just 2.2% were using Windows 8.1.
Cybersecurity experts warn that without ongoing updates, unpatched systems become vulnerable to exploits. “When there are no more updates, quickly-addressed exploits become open doors,” experts caution, suggesting ransomware groups could target millions of unprotected endpoints after October 14.
StatCounter reports an unexpected surge in Windows 7 usage, with nearly 140 million PCs still running the retired operating system.
Windows 11, which has struggled to gain widespread adoption, may see increased installation rates as a result of this impending security update deadline. Users are strongly advised to take action before October 14 to protect their systems and data.
