Windows 10 Support Ended: How to Upgrade, Stay Secure, and Use ESU

As of 14 October 2025, Windows 10 support ended, officially marking the end of free security updates, bug fixes, and technical support from Microsoft. While millions of users still rely on Windows 10 daily, continuing to use it without updates exposes systems to rising risks.

This change has left many asking the same urgent question: Is Windows 10 still supported at all? The answer: only through Microsoft’s Extended Security Updates (ESU) program. Without ESU or an upgrade to Windows 11, your device is now exposed to serious security vulnerabilities.

This guide walks you through all available options—whether that’s moving to Windows 11, enrolling in the ESU program, or using alternative strategies to reduce risk.

Key Security Risks Windows 10 Users Now Face

Running an unsupported operating system is like leaving your door unlocked. Without regular updates, your device becomes a soft target for attackers exploiting known vulnerabilities.

Microsoft Defender Antivirus will continue to receive definition updates, but it won’t protect against deep system-level threats. As TechRadar explains, antivirus tools are no replacement for core OS security patches. You’re now more exposed to:

• Zero-day exploits and ransomware
• Phishing attempts through unpatched browsers
• Software incompatibility with newer applications
• Compliance and legal risks for businesses

This is the reality after Windows 10 support ended—a system that works, but no longer protects.

Upgrade to Windows 11 for Full Support and Features

If your PC meets Microsoft’s system requirements—like TPM 2.0, Secure Boot, and a compatible processor—upgrading to Windows 11 is the best path forward. It ensures you continue receiving:

• Security updates and bug fixes
• Modern UI and feature enhancements
• Better support for new hardware and applications

You can check compatibility using the PC Health Check tool or explore upgrade options through Windows Update. For users with unsupported hardware, workarounds exist, but Tom’s Hardware warns that such installs may not receive all updates and are officially unsupported.

Windows 10 ESU Program: Limited Support After EOL

If upgrading is not immediately feasible, Microsoft offers the Windows 10 Extended Security Updates (ESU) program. It allows eligible users to continue receiving critical security patches.

What Is Included in the ESU?

• Security updates for critical vulnerabilities
• No new features or non-security fixes
• Available only for systems running Windows 10 version 22H2
• Requires enrollment via Windows Update or enterprise licensing

Microsoft’s official documentation confirms that ESU is available for both businesses and consumers. For home users, it’s typically available until October 2026, while enterprises can extend it until October 2028.

Costs for enterprise users increase annually. Consumers in supported regions may enroll through Settings > Windows Update, though they may be required to link their system to a Microsoft account.

Is Windows 10 Still Supported in Any Form?

Yes—but only if you’re using the ESU program. Otherwise, Windows 10 is no longer supported as of 14 October 2025.

This means:

• No free updates or feature releases
• No access to Microsoft technical support
• No guaranteed compatibility with new apps or drivers

If you’re not enrolled in ESU, your system is now considered unsupported. Over time, more developers will drop compatibility, and security threats will increase. After Windows 10 support ended, maintaining security becomes a user responsibility—not Microsoft’s.

What If You Can’t Upgrade or Enroll in ESU?

If your device doesn’t meet Windows 11 requirements and you can’t access ESU, you’re not entirely defenseless. Here are essential actions to reduce your vulnerability:

• Install a trusted third-party antivirus with real-time protection
• Use a hardware firewall or secure router to limit threats
• Avoid browsing unknown websites or downloading unverified files
• Remove outdated applications and unused services
• Create regular system backups and store them offline
• Limit internet access for older or vulnerable systems

These steps won’t fully replace official support, but they provide a temporary shield while you plan your long-term upgrade.

Final Thoughts: Secure Your System Before It’s Too Late

Since Windows 10 support ended, the clock is ticking. You have three choices: upgrade to Windows 11, activate the ESU program, or implement strict security measures. Whichever route you choose, doing nothing is the worst option.

If you’ve been wondering, “Is Windows 10 still supported?” — it’s not, unless you act. Unsupported systems bring unnecessary risk. Stay protected by upgrading or enrolling in ESU before it’s too late.

FAQs

Is Windows 10 still supported by Microsoft?
Only through the Extended Security Updates (ESU) program. Standard support ended on 14 October 2025.

How do I upgrade to Windows 11?
Use Windows Update or a clean install. Your PC must meet system requirements such as TPM 2.0 and Secure Boot.

How much does the ESU program cost?
It varies. For enterprises, it starts at around $61 per device/year and increases yearly. Consumer pricing depends on region and availability.

Can I use antivirus instead of upgrading?
Antivirus helps but doesn’t patch OS-level vulnerabilities. It’s a supplement, not a solution.

Will my apps keep working on Windows 10?
Some will, for now. But developers will gradually phase out support for an unsupported OS.

Is it legal to keep using Windows 10 after support ends?
Yes, but it may violate compliance standards for businesses or regulated industries without ESU.
