Windows 10 reached the end of support on October 14, 2025. For Home and Pro editions, that date has already passed. If your business is still running Windows 10 machines, you’re now operating on borrowed time — and every month you wait, the risk and the cost go up. (For reference, Softcoria publishes in-depth Windows software guides that document these deadlines.)
This isn’t a scare piece. It’s a practical breakdown of where things stand, what your options cost, and how to plan the move without disrupting your business.
What “End of Support” Actually Means
When Microsoft ends support for a Windows version, three things stop: security updates, bug fixes, and technical support. Your computers don’t stop working on the deadline. They just stop getting patched.
That’s the critical part. Every month, Microsoft publishes fixes for newly discovered vulnerabilities. After end of support, those fixes stop — but the vulnerabilities don’t. Attackers know exactly which systems are unpatched, because the list of fixed flaws is public. Running an unsupported operating system on a business network is like leaving the office unlocked and posting about it.
For most editions of Windows 10, that day was October 14, 2025. If you haven’t acted yet, your machines have been without security patches for months.
The LTSC Exception — and Its Limits
There’s one flavor of Windows 10 still standing: the Long-Term Servicing Channel (LTSC), designed for specialized systems like medical devices, industrial controllers, and kiosks. If your business happens to run it, the deadlines are different:
- Windows 10 Enterprise LTSC 2021 — supported until January 12, 2027
- Windows 10 Enterprise LTSC 2019 — supported until January 9, 2029
- Windows 10 IoT Enterprise LTSC 2021 — supported until January 13, 2032
Be honest with yourself, though: most businesses don’t run LTSC. It was never sold through normal retail channels, it lacks the Microsoft Store and many consumer features, and it was never intended as a general-purpose desktop OS. If you’re not sure which edition you have, you’re almost certainly not on LTSC. Don’t let the exception become your excuse to do nothing.
Option 1: Extended Security Updates (ESU)
Microsoft offers a paid lifeline called Extended Security Updates. It buys you security patches — only security patches, no new features — for a limited time. There are two versions, and the pricing tells you which one Microsoft wants you to choose.
Consumer ESU extends protection to October 12, 2027. For businesses, the relevant program is the Enterprise ESU, priced at $61 per device for Year 1, doubling each year after that — $122 in Year 2, $244 in Year 3 — running through January 8, 2030.
Do the math for your fleet. Ten machines cost $610 in Year 1, $1,220 in Year 2, and $2,440 in Year 3 — over $4,200 per device across the full program for ten PCs, and that’s just for patches. ESU makes sense as a bridge for a handful of machines that can’t be upgraded yet — legacy software, hardware constraints, compliance timelines. As a long-term strategy, it’s one of the most expensive ways to run old computers.
Option 2: Upgrade to Windows 11
For most businesses, the right answer is Windows 11. The upgrade itself is free for eligible devices, and the planning is the real work:
- Check hardware compatibility. Windows 11 requires TPM 2.0 and relatively recent CPUs. Machines more than about six years old often don’t qualify. Audit your fleet before you promise anyone a timeline.
- Test your line-of-business software. The accounting package, the CRM, the industry-specific tool nobody remembers buying — verify each one runs on Windows 11 before you migrate. One incompatible application can stall the whole project.
- Phase the rollout. Start with IT and a pilot group, then move department by department. Never upgrade everyone the week before quarter-end.
- Budget for replacements. Incompatible machines need replacing, not heroics. A new business PC costs less than a single ransomware incident — and with Windows 10 unsupported, that risk is no longer theoretical.
Option 3: Alternative Paths for Special Cases
Some machines don’t fit the standard plan. Kiosks, single-purpose terminals, and systems running irreplaceable legacy software may need creative solutions: network isolation (take them off the internet and the main network), virtualization (run the legacy app in a contained VM on a supported host), or in rare cases, a move to a different OS entirely. These are exceptions to manage, not strategies to default to.
The Hidden Costs of Doing Nothing
“We’ll get to it next quarter” is the most expensive sentence in IT. Beyond the direct security risk, consider the compounding costs that quietly accumulate while unsupported machines stay in service:
- Compliance exposure. If your industry has data-protection requirements, running unpatched systems can turn a breach into a liability nightmare.
- Insurance. Cyber-insurance policies increasingly ask about patch status. Unsupported systems can mean denied claims.
- Software compatibility. Vendors are already dropping Windows 10 from their support matrices. New versions of browsers, security tools, and business apps will stop working on it.
- Reputation. “Our customer data was stolen because we didn’t update Windows” is not a press release anyone wants to write. Customers and partners increasingly ask about security posture before signing contracts, and an unsupported fleet is a hard thing to explain in a due-diligence questionnaire.

Build the Plan This Week
You don’t need a six-month study. You need an afternoon:
1. Inventory — list every Windows 10 machine, its edition, and whether it meets Windows 11 requirements.
2. Triage — which machines upgrade, which get replaced, which (if any) get ESU as a bridge.
3. Budget — replacements plus labor, weighed against ESU’s escalating per-device cost.
4. Timeline — pilot this month, full rollout within the quarter.
Having one authoritative date sheet with the exact support deadlines ends the “I thought we had until 2027” conversations — circulate it internally before you finalize the budget.
The deadline already passed. The only question left is how much risk you’re willing to carry while you catch up — and the cheapest time to start was yesterday. The second-cheapest time is today.
