Windows 10 Support Has Ended: What Small Offices Should Do Now
Microsoft ended support for Windows 10 on October 14, 2025. Those computers still turn on and work, but they no longer get free security updates. Every new security hole found since then stays open on them, and that's exactly what attackers look for.
What "end of support" actually means
No more security fixes. New Windows 10 vulnerabilities aren't patched unless you pay for Extended Security Updates.
Software and devices move on. Over time, more apps, printers, banking sites and practice software stop supporting Windows 10.
Insurance and client questions. Cyber insurance applications and client security questionnaires increasingly ask whether you run unsupported systems.
Your options
Upgrade to Windows 11 for free if the PC meets Microsoft's requirements, including a supported processor and TPM 2.0. Many business PCs bought from about 2018 on qualify.
Replace PCs that can't upgrade. Older machines are usually due anyway, and a new PC with a solid-state drive is noticeably faster.
Buy Extended Security Updates as a short bridge. Microsoft sells yearly, security-only updates for businesses, priced per device and rising each year. It buys time but doesn't solve the problem.
A simple plan for a small office
List every computer and the version of Windows it runs.
Check which ones can upgrade to Windows 11 for free.
Upgrade those first, starting with the PCs that handle email, banking or client files.
Budget to replace the rest over the next few months, oldest and most exposed first.
