Windows 10 Extended Security Updates (ESU) Pricing for Australian Businesses

Introduction

With Windows 10 reaching its end of support on October 14, 2025, Australian businesses face a critical decision: upgrade to Windows 11, transition to cloud-based solutions, or enroll in Microsoft’s Extended Security Updates (ESU) program to continue receiving critical and important security updates. The ESU program provides a temporary bridge for businesses needing more time to migrate, but it comes with significant costs and considerations. This article explores the pricing structure for Windows 10 ESU in Australia, tailored for businesses, and offers insights into its implications, benefits, and alternatives.

Overview of Windows 10 ESU Program

The Windows 10 ESU program allows businesses to receive security updates for devices running Windows 10 Enterprise, Education, or Pro editions after the official support ends. These updates include critical and important security patches but exclude new features, non-security fixes, or general technical support. The program is designed as a short-term solution, with a maximum duration of three years, ending October 14, 2028.

Key Features

• Critical and Important Updates: Ensures protection against vulnerabilities.

• No Feature Updates: ESU focuses solely on security, not functionality enhancements.

• Limited Support: Technical assistance is restricted to ESU license activation and update installation issues.

• Cumulative Licensing: Businesses must purchase prior years’ licenses if enrolling late (e.g., starting in Year 2 requires paying for Year 1 as well).

Pricing for Australian Businesses

Microsoft has outlined a tiered pricing structure for the ESU program, with costs doubling each year to incentivize upgrading to Windows 11. Prices are in AUD, Below is the pricing breakdown based on available data:

Standard ESU Pricing (Per Device, Via Volume Licensing)

• Year 1 (November 2025 – October 2026): $105.60

• Year 2 (November 2026 – October 2027): $207.70

• Year 3 (November 2027 – October 2028): $416.50

• Total Cost Over 3 Years: $729.80

Education Pricing

Educational organizations in Australia benefit from significantly lower rates:

• Year 1: $1.90

• Year 2: $3.80

• Year 3: $7.60

• Total Cost Over 3 Years: $13.30

Free ESU Options

• Windows 365 Cloud PCs: Windows 10 devices accessing Windows 11 Cloud PCs via an active Windows 365 subscription are automatically entitled to ESU at no additional cost, provided the device is Microsoft Entra joined or hybrid joined and the user signs in with their Microsoft Entra ID at least once every 22 days.

• Azure Virtual Machines: Windows 10 virtual machines hosted on Azure (e.g., Azure Virtual Machines, Azure Dedicated Host, or Azure VMware Solution) receive ESU for free for up to three years.

Additional Notes

• Availability: Licenses can be purchased starting October 2024 through Microsoft Volume Licensing or from September 1, 2025, via Cloud Solution Provider (CSP) partners like CDW or Insight.

Implications for Australian Businesses

The escalating costs of ESU make it an expensive option for businesses with large device fleets. For example:

• A small business with 50 devices would pay ~$4,500 AUD in Year 1, $9,000 AUD in Year 2, and $18,000 AUD in Year 3, totaling ~$31,500 AUD over three years (standard pricing).

• Using the cloud management discount, the same business would pay ~$3,350 AUD, $6,650 AUD, and $13,300 AUD, totaling ~$23,300 AUD.

• Educational institutions with 50 devices would pay only ~$500 AUD over three years, making ESU far more viable for schools and universities.

These costs highlight the program’s role as a temporary measure, encouraging businesses to transition to Windows 11 or cloud solutions like Windows 365 to avoid long-term expenses.

Benefits

• Security Continuity: Protects against vulnerabilities post-October 2025, critical for compliance with Australian data protection regulations (e.g., Privacy Act 1988).

• Flexibility: Provides time to plan and execute Windows 11 upgrades, especially for devices not meeting Windows 11’s strict hardware requirements (e.g., TPM 2.0, supported CPUs).

• Cloud Integration: Free ESU for Azure and Windows 365 users makes cloud adoption attractive for Australian businesses already investing in Microsoft ecosystems.

Challenges

• Cost Escalation: Doubling prices each year can strain budgets, particularly for SMEs in Australia with limited IT resources.

• Limited Scope: No feature updates or general technical support, potentially leading to compatibility issues (e.g., Microsoft 365 apps may face performance issues on Windows 10 post-2025).

• Hardware Constraints: Many older devices may still need replacement to run Windows 11, making ESU a stopgap rather than a solution.

• Administrative Burden: Managing licenses and ensuring compliance (e.g., using 5×5 activation keys or Volume Activation Management Tool) requires IT expertise.

Alternatives to ESU

Australian businesses should weigh ESU against other options:

1. Upgrade to Windows 11: Free for eligible devices meeting hardware requirements. IT Mobile, for example, can assist with hardware assessments and upgrades (e.g., SSDs, RAM) to meet Windows 11 standards.

2. Transition to Cloud Solutions: Windows 365 or Azure Virtual Desktop offers free ESU and modernizes IT infrastructure, ideal for businesses in Gold Coast and Tweed Coast seeking scalable solutions.

3. Third-Party Security: Services like 0patch provide unofficial security patches for Windows 10, though they may not meet enterprise compliance needs.

4. Device Replacement: Investing in new Windows 11-compatible hardware through partners like Microsoft’s trade-in program or local retailers (e.g., JB Hi-Fi, Harvey Norman) may be more cost-effective long-term.

Considerations for Gold Coast and Tweed Coast Businesses

For businesses in Gold Coast and Tweed Coast, like those served by IT Mobile, ESU can be a practical interim solution for maintaining secure operations while planning upgrades. IT Mobile’s expertise in device optimization and data recovery can complement ESU by:

• Optimizing Windows 10 devices to ensure compatibility with ESU updates.

• Recovering data from HDDs, SSDs, or portable storage during migrations to new systems.

• Providing local, same-day support to manage ESU license activation and update deployment.

However, businesses should budget carefully, as ESU costs can quickly outweigh the benefits of delaying upgrades, especially for larger fleets.

Conclusion

The Windows 10 ESU program offers Australian businesses a lifeline to maintain security post-October 2025, but its escalating costs—starting at ~$105.60 AUD per device and reaching ~$729.80 AUD over three years—make it a short-term strategy. Educational institutions benefit from low-cost options (~$10 AUD total), while cloud-based solutions like Windows 365 and Azure provide free ESU, making them attractive for forward-thinking businesses. Gold Coast and Tweed Coast companies can leverage local IT providers like IT Mobile to navigate this transition, ensuring secure, efficient operations while planning for Windows 11 or cloud adoption.
