Microsoft Issues New Security Warning for Windows 10. Here’s What You Need to Do

Microsoft’s Windows 10 Support Ends Soon: Here’s What You Need to Know

In a major shift for PC users worldwide, Microsoft has officially ended support for Windows 10 as of October 14, 2025. Despite this deadline, an estimated 1 billion computers were still running the decade-old operating system by the end of last year. Now, with the clock ticking, millions of users face a critical decision: upgrade to Windows 11 or risk losing vital security protections.

The Urgency Behind the Deadline

On February 10, 2026, Microsoft announced a significant development that adds urgency to the situation. The original Secure Boot certificates—essential components that prevent Windows machines from running insecure software—are set to expire in June 2026. This expiration could leave unprotected systems vulnerable to security threats, making the upgrade to Windows 11 or enrollment in Microsoft’s Extended Security Updates (ESU) program more critical than ever.

Extended Security Updates: A Temporary Lifeline

Recognizing that many users aren’t ready to transition to Windows 11, Microsoft has extended Windows 10 support by one additional year. Users can enroll in the ESU program to continue receiving security updates through October 13, 2026. However, Microsoft emphasizes that this is “not intended as a long-term solution but rather as a temporary bridge to stay secure while one migrates to a newer, supported platform.”

The Cost Factor

While the ESU program costs $30 for most users, there’s good news for European users—Microsoft is offering the service absolutely free in Europe. For users in other regions, there are two alternative free enrollment options: syncing Windows settings to a OneDrive account or redeeming 1,000 Microsoft Rewards points.

How to Enroll in ESU

To qualify for ESU, users must be running the latest version of Windows 10 (version 22H2). After confirming your system is up to date, navigate to Settings > Windows Update and look for the enrollment option. The process involves choosing between backing up your PC settings to OneDrive, paying the $30 fee, or using Microsoft Rewards points.

Free Enrollment Options

For those seeking free security updates, Microsoft offers two pathways. The first involves using Windows Backup to sync your settings with OneDrive—though users should be aware that Microsoft’s free storage tier is limited to 5GB. The second option requires redeeming 1,000 Microsoft Rewards points, which may be more appealing for users with accumulated points.

The Windows 11 Alternative

For users considering the upgrade path, Windows 11 represents Microsoft’s latest operating system. However, not all Windows 10 devices meet the system requirements for the upgrade. Microsoft provides detailed instructions for checking compatibility, particularly after changing device hardware.

What’s Next?

As Microsoft continues rolling out the ESU enrollment wizard to all eligible users, some have reported delays in accessing the program. The company has acknowledged these rollout issues and is working to restore availability in certain markets.

With Windows 10’s final sunset date approaching, users face a crucial decision point. Whether choosing to upgrade to Windows 11 or enrolling in the ESU program, taking action before the October 2026 deadline is essential for maintaining system security and functionality.
