Windows 10 reached end of support on October 14, 2025. Every business still running Windows 10 faces three choices: upgrade to Windows 11, pay for Extended Security Updates, or accept growing security and compliance risks. Here is how to choose and execute the right path.
Windows 10 end of support happened on October 14, 2025. Despite years of warnings, roughly 40 percent of business devices were still on Windows 10 at the end of life milestone. If your business is among them, you face three distinct options — each with different costs, timelines, and risk profiles.
Option 1: Upgrade to Windows 11. This is the right choice for most businesses but has hardware compatibility implications. Windows 11 requires TPM 2.0, UEFI Secure Boot, and a supported CPU — hardware requirements that exclude many devices manufactured before 2018. Approximately 30 percent of Windows 10 business devices cannot upgrade to Windows 11 without hardware replacement. For compatible devices, the upgrade is free and can be done in-place without data loss.
Option 2: Extended Security Updates (ESU). Microsoft offers paid security updates for Windows 10 for up to three years post-end-of-life, but at escalating costs. Year 1 ESU costs 61 dollars per device. Year 2 doubles to 122 dollars. Year 3 doubles again to 244 dollars. For a 50-device business, that is 3,050 dollars in year 1, 6,100 in year 2, and 12,200 in year 3 — 21,350 dollars total just to buy time. ESU makes sense for specific edge cases like specialized industrial PCs running custom software, but rarely for general business use.
Option 3: Accept the risk. Some businesses continue running Windows 10 without ESU. This is dangerous and increasingly expensive. Cyber insurance policies increasingly exclude unsupported operating systems. Compliance frameworks including HIPAA, PCI-DSS, and SOC 2 require supported operating systems. Security vulnerabilities will continue to be discovered but not patched, making these devices easy targets for attackers.
The right approach for most businesses: complete a hardware inventory, identify Windows 11 compatible devices and upgrade them immediately, budget device refresh for incompatible hardware over 6 to 12 months, use ESU only as a bridge for specific devices that cannot be replaced in that timeline. For a typical 50-person business, the cost to migrate is 30,000 to 75,000 dollars for new hardware where needed, compared to 21,350 dollars for three years of ESU that still leaves you on an end-of-life operating system.
CloudTechForce manages Windows 11 migrations as part of our managed IT services. Our migration approach includes hardware compatibility assessment, phased deployment planning, automated Windows 11 deployment through Intune Autopilot, application compatibility testing, user training, and zero-touch provisioning of new devices. Our clients complete migrations in 3 to 6 months with minimal user disruption.
