Microsoft has officially announced the end of support for the Windows 10 operating system, effective October 14, 2025. This decision marks a significant, albeit controversial, transition that leaves an estimated 400 million PCs at substantial risk due to their inability or owners’ unwillingness to upgrade to Windows 11.
The end of support means that Microsoft will cease providing free software updates, technical assistance, and, most critically, security fixes. While computers running Windows 10 will continue to function, they will become increasingly vulnerable to malware, data breaches, and cyberattacks as newly discovered security flaws go unpatched.
The Core Problem: Hardware Incompatibility and Obsolescence
The primary challenge driving this risk is the stringent hardware requirements for Windows 11, particularly the mandatory presence of a TPM 2.0 (Trusted Platform Module) chip and specific CPUs. Millions of PCs that are otherwise perfectly functional do not meet these requirements and cannot be upgraded for free, leading to accusations of planned obsolescence from consumer groups.
The Public Interest Research Group (PIRG) highlights the “staggering” scale of this security threat and environmental concerns. The forced obsolescence of hundreds of millions of functional computers will result in significant electronic waste (e-waste), generating over 70 million tons of CO2.
Options for Windows 10 Users
Users facing the end of Windows 10 support have three main pathways to mitigate the risk:
- Upgrade to Windows 11: This is the best long-term solution, offering the latest features and security. It is a free upgrade for eligible devices. Users with incompatible hardware, however, must purchase a new PC.
- Extended Security Updates (ESU): Microsoft offers an ESU program that provides security updates for up to an additional year (until October 2026). This program is intended to give users extra time to migrate.
- Consumers can enrol in the first year of ESU for free by syncing their Windows settings with the cloud using Windows Backup or by redeeming Microsoft Rewards points. Otherwise, the cost is approximately $30 for the first year, doubling each subsequent year.
- Commercial and Enterprise users face substantially higher, rising subscription fees for ESU access.
- Alternative Operating Systems: For older, incompatible hardware, switching to a free, open-source operating system like Linux or ChromeOS is a viable, safe alternative that ensures continued security updates.
European Concessions
Following pressure from consumer organizations like Euroconsumers, Microsoft conceded a free one-year ESU option for European users, although activists argue this is an insufficient measure to address the massive problem of electronic waste and technological abandonment. Cybersecurity experts strongly advise all users to have a concrete plan of action before the October 2025 deadline.
