Still on Windows 10? Your options after end of life
Windows 10 support ended on October 14, 2025. That deadline has come and gone — and yet plenty of businesses are still running Windows 10 machines every day. If that's you, this isn't a lecture. It's a practical rundown of what running Windows 10 in 2026 actually risks, and the three realistic paths forward.
(If you want the background on what "end of life" means and what Windows 11 requires, we covered that when the deadline hit in our original Windows 10 end-of-life article.)
What running unpatched Windows 10 means in 2026
Nothing dramatic happened on October 15, 2025. Your Windows 10 machines kept booting, printing, and running your software. That's exactly why this problem is dangerous — the risk is invisible and it compounds monthly.
- Every Patch Tuesday widens the gap. Microsoft still publishes monthly fixes for Windows 11 and for Windows 10 ESU subscribers. Each of those fixes is also a public roadmap of vulnerabilities that your unpatched Windows 10 machine shares — and will never receive.
- Attackers specifically hunt end-of-life systems. An unsupported operating system is the softest target on any network, and automated scanning tools find them fast.
- Software support is drying up. Browsers, business applications, and drivers are progressively dropping Windows 10, so even non-security problems get harder to fix.
- Compliance and insurance exposure. Cyber-insurance questionnaires and frameworks like HIPAA and PCI expect supported, patched systems. An unsupported OS can jeopardize a claim or an audit.
One outdated PC is enough — attackers use the weakest machine as the door into everything else on your network.
Your three real options
Option 1: Extended Security Updates (a bridge, not a destination)
Microsoft sells Extended Security Updates (ESU) for Windows 10 — continued security-only patches for machines you genuinely can't migrate yet. Consumer ESU covers a single year (through October 2026), while the business program can be renewed annually for up to three years, with the price roughly doubling each year to push you toward migration.
ESU buys time for machines tied to legacy software or specialized equipment. It does not buy new features, bug fixes, or long-term viability. Treat it as a bridge with a toll that goes up every year — and note that for consumers, that bridge ends in October 2026.
Option 2: Upgrade the PCs that qualify
The Windows 11 upgrade is free for eligible Windows 10 machines. Eligibility is the catch: Windows 11 requires TPM 2.0, Secure Boot, and a supported processor — requirements many pre-2019 PCs don't meet. For the machines that do qualify, upgrading is usually straightforward: verify compatibility, back everything up, upgrade, confirm your applications still work.
"Usually straightforward" across twenty machines still means twenty backups, twenty upgrades, and twenty rounds of application testing — which is why most businesses schedule it in waves rather than winging it.
Option 3: Replace the hardware that doesn't
For machines that can't run Windows 11, replacement is the honest answer. Registry hacks to force Windows 11 onto unsupported hardware exist, but they leave you in unsupported territory — the very problem you're trying to escape. A PC old enough to lack TPM 2.0 is typically 6+ years old, near the end of its useful life anyway, and often costing you more in slowness and downtime than a replacement would. New machines come with supported Windows 11, current security hardware, and several years of runway.
How an MSP handles the migration for you
The reason businesses put this off isn't the cost — it's the coordination. A managed migration looks like this:
- Inventory and assessment: every machine checked against Windows 11 requirements, so you know exactly what upgrades free vs. what needs replacing.
- A phased plan: upgrades and replacements scheduled around your business calendar, a few machines at a time, with ESU as a stopgap only where genuinely needed.
- Data protection first: full backups before any machine is touched, and files, settings, and applications migrated to new hardware.
- After the move: old drives securely wiped, and new machines patched and monitored going forward.
Staff keep working. Nothing gets lost. Nobody spends a Saturday reinstalling QuickBooks.
The longer you wait, the fewer options you have
ESU windows are closing, and every month adds unpatched vulnerabilities to machines that aren't covered. If you've still got Windows 10 in your office, the right time to plan the exit was last year — the second-best time is now.
