When Microsoft ends support for a product, it’s a shift that affects security, productivity, and budgets across the business landscape. For small and midsize businesses (SMBs), Windows 10 end-of-life (EOL) is one of those moments. It’s not just about upgrading operating systems. It’s about managing risk and preparing your business for the next phase of IT modernization. 

Key Dates & What EOL Means 

Microsoft officially ends support for Windows 10 on October 14, 2025. After that date, the operating system will no longer receive security patches, bug fixes, or technical support. For SMBs still running Windows 10, every unpatched device becomes a potential security vulnerability, a ticking clock for compliance and operational risk. 

According to StatCounter, approximately 40% of all Windows users worldwide still run Windows 10 as of 2025. Many SMBs are in that mix, with older hardware or critical applications still tied to legacy systems. In early 2020, 66% of SMB devices were running Windows versions that had expired or were about to. This pattern shows a long-standing challenge: SMBs often delay upgrades due to budget constraints or fear of disruption. 

However, Windows 10 EOL isn’t something that can be safely postponed. Once support ends, cybercriminals will quickly exploit the growing pool of unpatched systems. Without updates, compliance requirements become harder to meet. That’s why now is the time to start planning. 

Your Options (Upgrade, ESU, Refresh) 

Microsoft has outlined three main paths forward for businesses still using Windows 10. Each has pros, cons, and ideal use cases depending on your organization’s environment. 

1. Upgrade to Windows 11 

For most SMBs, the natural path forward is upgrading to Windows 11. It improves performance, enhances security features like TPM 2.0 enforcement, and integrates with modern collaboration tools like Microsoft Teams and OneDrive.  

However, the biggest challenge for many SMBs lies in hardware compatibility. Older systems may not meet Windows 11’s processors, TPM, and secure boot requirements. 

Before upgrading, conduct an inventory of all devices and applications. Determine which systems can handle Windows 11 and which will need replacement. An IT partner can assess compatibility to identify bottlenecks and plan phased deployments. User profiles, apps, and policies can sync smoothly through cloud management solutions like Intune or Azure AD for SMBs using Microsoft 365 and Windows services. 

2. Purchase Extended Security Updates (ESU) 

If upgrading isn’t immediately possible, Microsoft offers Windows 10 ESU options. The ESU program provides paid access to critical and important security updates for up to three years after the 2025 deadline. While this buys time, it’s not a long-term fix. Costs increase annually, and ESU doesn’t include new features or technical support. It’s a stopgap designed for organizations that need additional runway to complete their migrations. 

For example, if your business runs specialized software that isn’t yet compatible with Windows 11, ESU can protect those systems while you plan a controlled transition. However, relying on ESU indefinitely is costly and risky. It’s best treated as a bridge, not a destination. 

3. Refresh Devices 

The third option is a device refresh, replacing older systems that can’t support Windows 11. While this may seem expensive upfront, it often provides better long-term value.  

New hardware has improved performance, lower energy consumption, and built-in security enhancements. This path aligns with predictable hardware procurement and lifecycle management practices, helping SMBs maintain stable, supportable environments. 

Many managed IT providers, including Blue Team Networks, help clients design staggered refresh cycles, replacing portions of the fleet annually to balance costs and minimize disruption. Combining this approach with leasing or hardware-as-a-service (HaaS) models can smooth out budgeting over multiple years. 

Building the Rollout Plan (Apps, Imaging, Timelines) 

Once you’ve chosen your path, the next step is developing a structured rollout plan. A successful Windows migration is part technical project and part change management exercise. 

Start with application compatibility testing. Identify your mission-critical software and confirm whether newer versions support Windows 11. Tools like Microsoft’s App Assure program can help verify functionality, and managed service providers can perform sandbox testing to catch conflicts early. 

Next, build your imaging and deployment strategy. Standardized system images ensure consistency across devices, reducing future troubleshooting time. This is where your IT partner’s experience can save countless hours, creating a tested base image with drivers, updates, and essential applications preloaded. 

Then comes timeline planning. Rollouts should be staged, beginning with pilot groups that can provide feedback before a wider launch. Many SMBs underestimate how long migration projects take. Between testing, scheduling, and user training, a smooth transition can span several months. Starting now ensures your business won’t be scrambling as the deadline approaches. 

Budget & Risk Considerations 

Planning for Windows 10 EOL is a financial decision too. SMBs should view this as an opportunity to optimize IT budgets rather than a forced expense. 

A clear device refresh and budgeting plan starts with understanding the total cost of ownership. Maintaining outdated systems can cost more, from increased support hours to downtime and security breaches. 

From a security and compliance standpoint, unsupported operating systems pose significant risks. Businesses in regulated industries must maintain systems that receive security updates. Running Windows 10 past its EOL can jeopardize compliance certifications and insurance coverage. And as cyberattacks grow more sophisticated, attackers will target businesses that delay. 

The budgeting conversation should also consider productivity gains. Newer devices paired with Windows 11 deliver faster boot times, better multitasking, and improved integration with modern collaboration platforms. These efficiencies translate into real financial benefits, especially for hybrid work environments.
