  3. Understanding Extended Security Updates (ESU) for Windows 10

A Bridge, Not a Destination

Microsoft will officially end support for Windows 10 on October 14, 2025. For many organizations, this milestone brings both urgency and uncertainty. What happens if you can’t upgrade every device in time? That’s where Microsoft’s Extended Security Updates (ESU) program comes in—a temporary safety net, but not a long-term solution.

What Is ESU?

Extended Security Updates (ESU) is a paid program from Microsoft that provides critical and important security updates for Windows 10 devices after official support ends.

Annual Licensing

ESU is available on an annual, per-device basis as a paid Microsoft program.

Compliance Support

It helps organizations maintain security and compliance while migrating to Windows 11.

Why Is ESU Needed?

Without ESU, organizations running Windows 10 beyond its end-of-support date face increased exposure to security vulnerabilities, regulatory non-compliance, and operational risk.

End of Support

After October 14, 2025, Windows 10 will no longer receive security updates, patches, or technical support.

Security Risks

Unsupported systems are vulnerable to cyber threats, malware, and compliance violations.

Upgrade Challenges

Legacy apps or hardware may prevent timely upgrades across all devices.

Time Buffer

ESU gives you extra time to stay protected while completing your transition plan.

Key Points About ESU

Understanding the scope, limitations, and eligibility requirements of ESU ensures your organization uses it effectively while staying secure and compliant during the transition from Windows 10.

Temporary Coverage

ESU is a short-term bridge, typically available for up to 3 years, with increasing annual costs.

Security Only

It includes critical and important security updates only—no new features or non-security fixes.

Version Requirement

Devices must be running Windows 10, version 22H2 to qualify.

Compliance Assurance

ESU helps maintain regulatory compliance during your migration window.

Best Practices for ESU

A strategic approach to ESU ensures you maintain protection and compliance while actively working toward full migration from Windows 10.

Inventory Devices

Identify all Windows 10 machines and assess their upgrade readiness.

Prioritize Replacement

Create a roadmap to upgrade or replace devices as soon as possible.

Use Strategically

Apply ESU only to devices that cannot be upgraded in time.

Plan for the End

There is no renewal after the final ESU year—plan your full migration accordingly.

Transition with Confidence

As the deadline approaches, the smartest move is to act now. Extended Security Updates (ESU) offer a temporary shield—but not a long-term strategy. By proactively planning your migration, prioritizing upgrades, and using ESU only where absolutely necessary, you’ll ensure your organization remains secure, compliant, and ready for what’s next.
