Still Running Windows 10? Houston Businesses Face Growing Security Risk — Here Are Your Three Options
Microsoft stopped supporting Windows 10 on October 14, 2025. If your Houston business is still running it—and many are—your computers are no longer receiving security updates. Everything still turns on. Applications still open. The network still works. That familiar continuity is precisely what makes this easy to put off. But every month a Windows 10 machine runs without patches, the number of unaddressed security vulnerabilities accumulates. None of them will ever be fixed.
For a Houston healthcare clinic, a Katy-area professional services firm, or a manufacturing company in The Woodlands, an unpatched endpoint is not an abstract risk. It is a specific liability that cyber insurance underwriters, compliance auditors, and the attackers who scan for end-of-life systems evaluate systematically. We covered the early warning signs of this transition in our post on Windows 10 retiring and whether your business was ready—that window has now closed. Managed IT services in Houston that include active device lifecycle management are what keep businesses off that list.
What “End of Support” Actually Means
When Microsoft ends support for a version of Windows, the monthly security patches stop. The operating system continues to function, but Microsoft has stopped closing the vulnerabilities being discovered in it. Security researchers and attackers keep finding new flaws in Windows 10—the code doesn’t disappear—but now nobody is issuing fixes. Every new vulnerability discovered becomes a permanent, unpatched attack surface on any machine still running the software.
The UK’s National Cyber Security Centre notes that flaws in unsupported products stay exploitable for as long as those products remain in use, and that relatively low-skilled attackers can take advantage of them using publicly available tools. That is the realistic threat model for Houston SMBs still running Windows 10 in 2026.
Why This Creates Real Risk for Houston Businesses
The security exposure is the most immediate consequence, but it is not the only one.
Compliance exposure. Organizations handling payment card data under PCI-DSS, health records under HIPAA, or personal data under other frameworks are expected to run supported, actively patched operating systems. Windows 10 no longer qualifies. For Houston healthcare practices and financial firms, running end-of-life software can trigger a compliance finding during an audit.
Cyber insurance complications. Insurers are increasingly asking, as part of renewal underwriting, whether systems are current and patched. An organization running end-of-life software may face higher premiums, reduced coverage limits, or a denied claim following an incident where the unpatched operating system was the entry point.
Software compatibility drift. As Windows 10 recedes, browsers, accounting systems, line-of-business applications, and security tools will drop support for it. Some already have. The moment a critical business application stops receiving Windows 10 updates, the organization faces a forced migration under pressure rather than on a planned timeline it controls.
Your Three Options
Most Houston businesses with Windows 10 devices face a mix of all three options across their fleet. The right answer for each machine depends on its age, its role, and the cost of the alternatives.
Option 1: Upgrade to Windows 11 (Free for Qualifying Hardware)
If the machine was purchased within the past several years, upgrading to Windows 11 is free and is almost always the right decision. Windows 11 requires a supported processor, a TPM 2.0 security chip, and Secure Boot capability. Microsoft’s PC Health Check application confirms whether a specific machine qualifies. Machines that qualify can be upgraded without losing files or installed applications. For Katy and Houston businesses with a relatively recent fleet, this option eliminates the problem at no hardware cost.
Option 2: Extended Security Updates as a Bridge
For machines that cannot run Windows 11, Microsoft offers Extended Security Updates (ESU) to keep monthly security patches running on a temporary basis. For businesses, the cost is $61 per device for the first year and doubles each subsequent year for up to three years—approximately $427 per device over the full period if used to the end. ESU provides security patches only: no new features, no technical support, no long-term path forward. It is a bridge to buy time while the hardware decision is made, not a substitute for migration. For machines with 12 to 18 months of useful life remaining, ESU makes sense. As a multi-year strategy, the escalating costs make replacement more economical.
Option 3: Replace the Machine
Some machines are too old to qualify for Windows 11 and not worth the escalating ESU fees. A replacement PC that ships with Windows 11 pre-installed is often the more cost-effective option once ESU costs and the ongoing burden of aging hardware are factored together. For The Woodlands and Houston businesses running equipment from 2017 or earlier, replacement is typically the cleaner and more budget-predictable answer—and it resets the device lifecycle clock entirely.
How to Plan the Transition Without Disrupting Operations
A practical approach for any Houston business looks like this: inventory every device still running Windows 10; use the PC Health Check tool or your managed IT provider in Houston to identify which qualify for a free Windows 11 upgrade; upgrade those first; then decide whether remaining machines get ESU or replacement based on age, role, and cost. The inventory takes an afternoon. The upgrade planning takes another. None of this needs to happen simultaneously, and none of it needs to disrupt operations—but it does need a plan, because running end-of-life software without one is a liability that compounds every month.
What Elevate Technology Delivers for Houston IT Management
Elevate Technology manages device lifecycle and IT infrastructure for businesses across Houston, Katy, and The Woodlands, including Windows 11 migration planning, hardware assessments, and ongoing patch management. If you are searching for managed IT services near you in the greater Houston area, this is exactly the kind of planned migration we handle regularly for SMBs. We run the inventory, confirm eligibility for free upgrades, coordinate the transition, and procure replacement hardware for machines that need it—so your team keeps working without interruption throughout the process. IT support in Houston that includes proactive device management is what separates a controlled migration from an emergency one.
Is it really dangerous to keep running Windows 10 if everything still seems to work?
Yes. The absence of visible symptoms is not evidence of safety. Every new vulnerability found in Windows 10 after October 14, 2025 is now a permanent, unpatched attack surface. Attackers actively scan for devices running end-of-life software because those vulnerabilities are known and will never be fixed. For Houston businesses in regulated industries or those that carry cyber insurance, the risk is not just a security matter—it is a compliance finding and a potential claims issue.
Can we avoid buying new hardware by paying for Extended Security Updates instead?
ESU is a legitimate short-term bridge for machines that cannot upgrade to Windows 11 but still have a useful business role. At $61 per device in year one, doubling each year, the cost adds up quickly—and ESU provides no new features, no application support, and no long-term path. For most Houston businesses, it makes economic sense for machines with 12 to 18 months of remaining useful life, not as a multi-year strategy. Your managed IT provider can run the numbers on your specific fleet and show you the cost comparison before you commit.
