What You Need to Know About Extended Security Updates for Windows 10

Windows 10 officially reaches end of life on October 14, 2025, and for many businesses, that date is closer than it seems. Microsoft’s Extended Security Updates (ESU) offer a temporary lifeline, but at a cost that increases each year and with limited protection. If you’re unsure whether to invest in ESU or move to Windows 11, we can help. Learn what ESU really provides, what it doesn’t, and why your IT roadmap needs a longer view.

A Timeline of Windows 10 End of Life

While many businesses still rely on Windows 10 for its stability and familiarity, that comfort zone is shrinking fast. After nearly a decade of service, the platform is approaching its final support deadline: October 14, 2025.

Once the official support period ends, Microsoft will no longer patch security vulnerabilities for devices running Windows 10—unless you opt into the Extended Security Updates (ESU) program. For organizations without a clear upgrade plan, this creates a difficult choice: pay for ESU to maintain compliance and security, or accept the risks of running an unsupported OS.

And while ESU buys you time, it doesn’t buy much else.

What Extended Security Updates Include

The Extended Security Updates program is often misunderstood. It’s not a way to extend the full benefits of Windows 10, it’s a stopgap measure, offering limited protection for those who truly can’t upgrade yet.

At its core, ESU provides security-only updates. There are no feature enhancements, no performance boosts, and no access to Microsoft’s standard support channels. The purpose is singular: plug critical security holes while giving IT teams more time to transition to supported systems.

Here’s What You Get (and Don’t Get) With ESU:

After enrolling in the program, your devices will continue to receive patches for high-risk vulnerabilities. However, they won’t receive:

Feature updates: Any new tools, UX improvements, or refinements released for Windows 11 are out of reach.
Non-security fixes: Minor bugs or stability issues won’t be addressed unless they pose a serious security risk.
Tech support from Microsoft: Standard support routes are discontinued unless you’re paying for another support plan.
Additional technical support: Tech support for most software that continues to run on an unsupported operating system will no longer be applicable.

It’s a minimal level of coverage, designed to prevent the worst-case scenarios, but it’s far from a long-term solution.

How the ESU Pricing Structure Works

Extended Security Updates are limited in scope, and they’re also increasingly expensive. Microsoft uses a tiered annual pricing model designed to encourage upgrades, not sustain outdated operating systems. Each year you stay on ESU, the cost increases, often doubling from the year before.

This escalating model is intended to make ESU a short-term bridge, not a comfortable long-term option. And while Microsoft has yet to release official public pricing for every edition, past precedent gives us a clear picture of what to expect.

Expect Compounding Costs, Not Predictable Rates

For example, with Windows 7’s ESU program, businesses saw fees grow annually:

Year 1: Baseline ESU cost per device
Year 2: Roughly double the cost of Year 1
Year 3: Even higher, with further limitations and fewer vendor integrations

If Microsoft follows the same playbook for Windows 10, organizations could be looking at thousands of dollars annually just to secure legacy systems—without gaining any new features or improvements.

For businesses with dozens or hundreds of affected machines, those costs stack up fast. And because Microsoft licenses ESU on a per-device basis, there’s no opportunity to share or scale benefits across your environment. Each machine adds to the bottom line.

From hardware requirements to app compatibility and IT support readiness, there’s a lot to consider before the end of Windows 10. Get a practical breakdown of what your business needs to upgrade smoothly and confidently.

When Extended Security Updates Might Make Sense

Despite their drawbacks, Extended Security Updates (ESUs) can serve a purpose in very specific business scenarios. They’re not designed to be a long-term solution, but in the short term, they may provide just enough runway to address internal challenges.

You Have Legacy Software That Won’t Run on Windows 11

Some critical business applications, especially custom or industry-specific ones, may not be compatible with Windows 11. In these cases, ESUs can buy you time to:

Evaluate and replace legacy software
Work with a developer to modernize the application
Complete testing and training for a new solution

But even in this case, the goal should be transition, not indefinite delay.

Your Hardware Isn’t Ready

If your business recently invested in hardware that doesn’t meet Windows 11’s requirements, a temporary ESU subscription might make sense. This gives you time to budget for new devices and plan a phased rollout. Still, the rising ESU costs mean this isn’t a reason to postpone indefinitely.

You’re In a Regulated Industry

For organizations in healthcare, finance, or other regulated sectors, running unsupported software can quickly violate compliance standards. If you’re behind on upgrading but can’t afford a compliance gap, ESUs can act as a temporary bandage.

However, regulators and auditors still expect a clear migration plan, and ESUs aren’t a license to stand still.

Why Upgrading to Windows 11 Is the Better Move

In nearly every other case, upgrading to Windows 11 offers stronger long-term value than clinging to Windows 10 with ESUs. Here’s why the smarter business move is usually to upgrade:

Better Security and Built-In Support

While ESUs patch critical vulnerabilities, Windows 11 provides important security updates, platform support, and compatibility improvements. You’re both securing your environment and modernizing it to meet today’s threats.

No Compounding Costs

Upgrading to Windows 11 is a one-time lift, not a recurring fee. Once you’re on the latest OS, you get regular updates without the escalating expenses that come with ESUs.

Access to Modern Features and Performance

Windows 11 delivers speed and usability upgrades, including enhanced multitasking, better memory management, and integration with modern hardware. Teams benefit from a smoother, more responsive experience, which directly improves productivity.

Stronger Compatibility With Modern Tools

Cloud platforms, virtualization solutions, cybersecurity software, and even printers are increasingly optimized for Windows 11. By upgrading, you keep your ecosystem aligned with the broader tech landscape, avoiding limitations and workarounds.

Final Verdict: Don’t Pay More to Stand Still

Extended Security Updates may seem like a convenient fix, but they’re a costly way to maintain the status quo. You’re not gaining new features, improving performance, or addressing the root of the problem—you’re simply buying time, at a premium.

For a very narrow set of use cases, ESUs can act as a short-term bridge. But the program isn’t designed for long-term use, and the rising yearly costs reflect that. Each passing year brings you closer to spending more money on less value.

The better investment? A thoughtful upgrade plan that future-proofs your environment, minimizes disruption, and aligns with your business goals.
