Windows 10 support has ended. What should your business do next?
Microsoft ended standard support for Windows 10 on October 14, 2025. Windows 10 computers may still run, but most no longer receive regular security updates, bug fixes, or technical support. For a business, continuing without a plan can increase security, compliance, and operational risk.

Why Windows 10 end of support matters
- Security exposure: Unpatched vulnerabilities can give attackers an easier path into a device or network.
- Compliance concerns: Unsupported systems may conflict with security requirements in contracts, insurance policies, or regulated environments.
- Software compatibility: Business applications, security tools, and hardware vendors may gradually stop supporting Windows 10.
- Business disruption: Waiting for a device or application to fail can turn a planned transition into an urgent replacement.
Your practical options
1. Upgrade eligible computers to Windows 11
Best for computers that meet Windows 11 requirements, run reliably, and still have useful life remaining. Confirm hardware, application, peripheral, security, and backup readiness before upgrading.
2. Replace computers that are not good upgrade candidates
Best for aging, unreliable, or incompatible systems. A planned replacement reduces rushed purchases and gives you time to migrate applications and data cleanly.
3. Use Extended Security Updates as a temporary bridge
Microsoft’s paid commercial ESU program can provide critical and important security updates for eligible Windows 10 devices. Coverage is purchased by year, is cumulative, and should support a defined migration timeline—not become the long-term plan.
4. Isolate a system only when replacement is not yet possible
Some specialized systems cannot move immediately. Restrict access, reduce exposure, monitor closely, and document an owner and retirement date. Isolation lowers risk; it does not make an unsupported system safe.
A sensible next-step checklist
- Inventory every Windows 10 computer, including remote and rarely used devices.
- Identify each device’s owner, location, business purpose, and critical applications.
- Check Windows 11 eligibility and verify application and peripheral compatibility.
- Choose upgrade, replacement, temporary ESU coverage, or controlled isolation for each device.
- Prioritize high-risk and business-critical systems, then schedule the work.
- Confirm backups, security controls, and a recovery path before making changes.
