Security threats don’t wait for anyone—especially not for those still running Windows 10. With cybercriminals constantly seeking new vulnerabilities, like the October 2025 exploit targeting the Windows Agere Modem Driver (CVE-2025-24990), staying protected is more than just a best practice—it’s a necessity. Microsoft’s Extended Security Updates (ESU) program steps in as a lifeline, offering critical patches for those not yet ready to leap to Windows 11. Whether you’re an IT admin juggling dozens of endpoints or a home user weighing the cost of upgrades, enrolling in ESU before Patch Tuesday can mean the difference between a secure system and a costly breach. The program isn’t just for traditional PCs; it now covers Windows 365 Cloud PCs, reflecting the shift toward hybrid and remote work environments. And for consumers, Microsoft has even introduced options like free enrollment with Windows Backup, making security accessible without breaking the bank. For anyone relying on Windows 10, understanding and acting on ESU enrollment is a crucial step to keep threats at bay and avoid those dreaded end-of-support warnings (BleepingComputer).

Importance of Enrolling in ESU

Ensuring Continued Security

Enrolling in the Windows 10 Extended Security Updates (ESU) program is crucial for maintaining the security of devices still operating on Windows 10. Microsoft frequently patches security vulnerabilities that are actively exploited to bypass security protocols and gain unauthorized administrative privileges. For instance, in October 2025, Microsoft addressed a vulnerability in the Windows Agere Modem Driver, identified as CVE-2025-24990, which was being actively exploited to gain administrative access on devices (BleepingComputer). Such vulnerabilities highlight the importance of receiving timely security updates to protect against potential threats.

Avoiding End-of-Support Warnings

To be eligible for the ESU program, users must ensure that their systems are running Windows 10, version 22H2 Home, Professional, Pro Education, or Workstations edition. Additionally, all available updates must be installed via Windows Update. A recent bug caused incorrect end-of-support warnings on Windows 10 systems, underscoring the necessity of keeping systems updated to avoid unnecessary alerts and ensure continued support (BleepingComputer).

Managing Enrollment for Organizations

For organizations, enrolling in the ESU program involves purchasing licenses through Microsoft Volume Licensing or Cloud Solution Provider partners. Each device must be activated with a unique ESU key and managed using tools such as Intune, WSUS, or Configuration Manager. This structured approach ensures that all devices within an organization receive the necessary security updates, thereby mitigating the risk of security breaches (BleepingComputer).

Benefits for Cloud PC Users

Microsoft has extended the ESU program to include Windows 365 Enterprise Cloud PCs and Windows 365 Frontline Cloud PCs, allowing these devices to receive free enrollment into the program. This move ensures that cloud-based systems, which are increasingly used by organizations for their flexibility and scalability, remain secure and up-to-date with the latest security patches (BleepingComputer).

Options for Consumers

Consumers have multiple options for enrolling in the ESU program. If users are not backing up their Windows settings, they will be presented with different enrollment options, including enabling backups, using reward points, or paying a fee of $30. Notably, enabling Windows backup allows users to receive ESU updates for free. This can be done by navigating to Settings > Accounts > Windows Backup and enabling the first toggle under “Remember my preferences” (BleepingComputer).

Importance of Regular Backups

While Microsoft suggests backing up devices using the Windows Backup program, it remains optional. However, regular backups are recommended to ensure data integrity and facilitate recovery in the event of a system failure or data loss. This practice complements the security measures provided by the ESU program, offering an additional layer of protection for users’ data (BleepingComputer).

Long-Term Security Assurance

The ESU program provides security updates through October 13, 2026, ensuring that devices remain protected against new vulnerabilities that may be disclosed and exploited. Given the dynamic nature of cybersecurity threats, it is vital for users to remain enrolled in the ESU program to receive these essential updates and maintain the security of their systems (BleepingComputer).

Conclusion

While the previous sections have detailed the technical aspects of enrolling in the ESU program, this section emphasizes the broader implications of maintaining security and operational integrity for both individual users and organizations. By enrolling in the ESU program, users ensure that their devices remain secure, compliant, and operationally efficient, thereby safeguarding against potential threats and disruptions.

Final Thoughts

Enrolling in Windows 10 ESU isn’t just about ticking a compliance box—it’s about safeguarding your digital life or business operations against real, evolving threats. As recent vulnerabilities and active exploits have shown, attackers are quick to capitalize on unpatched systems. By leveraging ESU, organizations and individuals alike can extend the life of their devices while maintaining robust security. The program’s flexibility, from cloud PC coverage to consumer-friendly enrollment options, ensures that everyone has a pathway to protection. Regular backups, while optional, add another layer of resilience, helping users bounce back from unexpected incidents. Ultimately, staying proactive with ESU enrollment before Patch Tuesday is a smart move for anyone not ready to upgrade, ensuring continued security and peace of mind (BleepingComputer).
