Microsoft's Windows 10 Extended Security Updates (ESU) program provides critical security patches for businesses and organizations that need more time to transition to Windows 11. As Windows 10 reaches its end-of-life (EOL) on October 14, 2025, the ESU program becomes a crucial consideration for enterprises still relying on the operating system.

What Are Windows 10 Extended Security Updates?

Extended Security Updates (ESU) are paid security patches that Microsoft offers after an operating system's official support ends. These updates include critical and important security fixes but do not include new features or non-security updates. The ESU program is primarily targeted at organizations that require additional time to upgrade their systems to Windows 11 or migrate to cloud-based solutions like Windows 365.

Who Needs Windows 10 ESU?

  • Enterprises with legacy applications: Some businesses rely on specialized software that may not yet be compatible with Windows 11.
  • Organizations with large-scale deployments: Migrating thousands of devices takes time, and ESU provides a safety net during the transition.
  • Regulated industries: Certain sectors, such as healthcare and finance, have compliance requirements that necessitate extended security coverage.
  • Educational institutions: Schools and universities with limited IT budgets may need more time to upgrade their infrastructure.

Windows 10 ESU Costs and Pricing Structure

Microsoft has adopted a tiered pricing model for Windows 10 ESU, with costs increasing each year:

  • Year 1 (2025-2026): $61 per device
  • Year 2 (2026-2027): $122 per device (2x Year 1 price)
  • Year 3 (2027-2028): $244 per device (4x Year 1 price)

This escalating cost structure is designed to encourage organizations to complete their migration to Windows 11 as quickly as possible. Volume licensing customers may receive discounts, and Microsoft 365 subscribers might have alternative options available.

How to Get Windows 10 Extended Security Updates

There are several ways to access ESU:

  1. Volume Licensing: Available through Enterprise Agreement (EA), Enterprise Subscription Agreement (EAS), or Enrollment for Education Solutions (EES).
  2. Cloud Solution Providers: Organizations can purchase ESU through Microsoft's partner network.
  3. Retail channels: Limited availability for smaller businesses through select retail partners.

Alternatives to Windows 10 ESU

Before committing to Extended Security Updates, organizations should consider these alternatives:

  • Upgrade to Windows 11: The most straightforward solution if hardware meets requirements.
  • Windows 365 Cloud PC: Microsoft's cloud-based solution that provides a secure, always-up-to-date Windows experience.
  • Azure Virtual Desktop: For organizations looking to virtualize their Windows environment.
  • Third-party security solutions: Some vendors offer extended protection for outdated operating systems.

Technical Requirements for ESU

To receive Extended Security Updates, systems must meet these criteria:

  • Running Windows 10 version 22H2 (the final version of Windows 10)
  • Have the latest servicing stack update (SSU) installed
  • For enterprise environments, proper licensing through Volume Licensing programs

Planning Your Migration Strategy

Organizations should develop a comprehensive migration plan that includes:

  1. Hardware assessment: Identify devices that can upgrade to Windows 11 and those that need replacement.
  2. Application compatibility testing: Verify that critical business applications work on Windows 11.
  3. User training: Prepare employees for the transition to Windows 11's new interface and features.
  4. Pilot deployment: Test the upgrade process with a small group before full rollout.
  5. Budget planning: Account for both ESU costs and eventual upgrade expenses.

Security Risks of Staying on Windows 10 Without ESU

Continuing to use Windows 10 after October 2025 without ESU exposes organizations to:

  • Unpatched vulnerabilities: No security updates for newly discovered exploits.
  • Compliance violations: Many industry regulations require up-to-date security patches.
  • Increased attack surface: Outdated systems become prime targets for cybercriminals.
  • Limited support options: Microsoft won't provide technical support for unsupported versions.

Microsoft's Rationale for the ESU Program

The Extended Security Updates program serves several purposes for Microsoft:

  • Provides a safety net for organizations during transition periods
  • Generates revenue from customers who need additional time to upgrade
  • Encourages migration to newer platforms like Windows 11 and Azure
  • Maintains security standards across the Windows ecosystem

Making the Right Decision for Your Organization

The choice between purchasing Extended Security Updates or accelerating your Windows 11 migration depends on several factors:

  • Budget constraints: Weigh the cost of ESU against upgrade expenses.
  • Technical readiness: Assess your infrastructure's ability to support Windows 11.
