Windows 10 End of Support: What It Actually Costs Your Business to Stay Put

What “end of support” actually means for a business

Windows 10 standard support ended on 14 October 2025. Your PCs didn’t stop working — but the flow of security updates, feature updates and technical assistance from Microsoft did. That matters: an operating system that no longer receives security patches steadily accumulates known, published vulnerabilities that are never fixed. Antivirus helps, but it can’t substitute for missing operating-system patches. For a home user that’s a manageable risk; for a business holding client data, it’s a widening exposure that surfaces in insurance renewals, audits and client security questionnaires.

The free extension is for home users, not your business

In June 2026, Microsoft extended free consumer ESU enrolment to 12 October 2027 — and created a costly assumption. That extension is consumer only; commercial devices sit in a separate, paid programme. If you read “Microsoft extends Windows 10 support for free” and assumed your office was covered, it isn’t. The green column below is what a home user gets, the red is what a business faces:

Same operating system, same end-of-support date — completely different treatment.

What Extended Security Updates cost a business

Business ESU is bought per device through volume licensing. Microsoft’s list price starts at USD $61 per device for Year One and doubles for each consecutive year, to a maximum of three years — a clear, escalating curve:

Three details matter: the minimum purchase is a single licence, so small fleets can extend only the machines that need it; each device must run Windows 10 version 22H2 to be eligible; and these are Microsoft’s USD list price. The doubling is deliberate — ESU is a bridge to cross quickly, not a place to settle.

The cumulative trap most businesses miss

Here’s the part that catches people out: ESU can’t be bought for the current year alone.

The consequence is blunt. A business that ignores this until late 2026 doesn’t pay the Year Two price — it pays Year One plus Year Two, USD $61 + $122 = $183 per device, and gets nothing for that first payment. Delay doesn’t defer the cost; it stacks it.

What ESU does not give you

It’s easy to hear “security updates” and assume ESU keeps everything as it was. It doesn’t — it delivers critical and important security updates only. No new features, no non-security bug fixes, no technical support: if something breaks, you’re on your own. It also only covers Microsoft’s software. Third-party vendors are dropping Windows 10 support on their own timelines regardless of ESU, so your applications, browsers and security tools may lose support before your coverage even ends. ESU buys time, not a capable platform.

Upgrade, replace, or pay: how to decide

For most machines the answer isn’t ESU at all. There are three paths, and the right one depends on the individual device:

Treated as a budgeted decision for specific machines, ESU is sensible. Treated as a fleet-wide default, it’s an expensive way to postpone a migration you’ll do anyway. The businesses that handle this well plan it as a project, machine by machine, with on-site support to carry out the moves.

What PIP does about this

This is exactly the kind of problem managed IT services exist to take off your desk. PIP audits the fleet, checks every machine against Windows 11’s requirements, and sorts them into three buckets — upgrade now, replace this cycle, or extend with ESU for a defined reason — then stages the migration as a budgeted project, not a scramble the week updates stop.

The goal is simple: no machine left unpatched by accident, and no money spent on ESU for a PC that could have upgraded for free.
