Windows 10 Usage Among Small Businesses
As of early 2025, Windows remains the dominant operating system among small and medium-sized businesses (SMBs). According to a January 2025 IT trends report, the average device distribution in these organizations is:
- Windows: 56%
- macOS: 27%
- Linux: 20%
Furthermore, a recent poll conducted by Canalys revealed that over a third (35%) of channel partners said their SMB customers are either unaware of the Windows 10 end-of-service (EoS) deadline or have no plans to upgrade their PCs.
What Windows 10 End-of-Service (EoS) Means for Small Businesses
When an operating system reaches its end of service (or end of life), the developer — in this case, Microsoft — stops providing the following essential support services:
- Security Updates: No more patches for vulnerabilities, leaving systems open to malware and cyberattacks.
- Technical Assistance: Microsoft support will no longer address issues for Windows 10 users.
- Feature Updates: No further enhancements or performance improvements will be added.
While your Windows 10 device will still function, it will lack the critical protections and support needed to operate securely and efficiently in a modern business environment.
Risks of Staying on Windows 10
Failing to transition from Windows 10 can pose significant risks to your business. Here are some of the key threats:
1. Heightened Security Vulnerabilities
Once Microsoft halts security updates, any vulnerability discovered after October 2025 will remain unpatched, exposing your system to malware attacks, ransomware, and data breaches. For businesses handling sensitive customer data, this is especially concerning due to privacy and regulatory implications.
2. Software Compatibility Issues
Third-party software developers will also gradually stop supporting Windows 10. This could lead to scenarios where your essential applications, such as accounting tools or inventory management software, no longer function as intended. Over time, productivity and customer service may be impacted by software incompatibilities.
3. Poor System Performance
Outdated systems tend to become slow and unstable. Without updates to optimize performance, businesses could experience frequent crashes and inefficiencies, hindering day-to-day operations.
Migration Options for Your Business
1. Upgrade to Windows 11.
Windows 11 represents Microsoft’s latest operating system, built with enhanced security, productivity tools, and modern features. If your current hardware meets the minimum system requirements, upgrading to Windows 11 is a cost-effective solution as it is free for eligible devices.
Steps to Upgrade:
- Check compatibility via Windows Update (Settings > Privacy & Security > Windows Update).
- If compatible, select the “Upgrade to Windows 11” option and follow on-screen instructions.
- Backup critical business files before upgrading.
Consideration: If your hardware is older, it may not meet the requirements for Windows 11. Use Microsoft’s PC Health Check tool to confirm.
2. Purchase new devices.
If upgrading is not feasible due to hardware limitations, purchasing new devices preloaded with Windows 11 may be the best option. Modern business laptops and desktops come equipped with faster processors, longer battery life, and enhanced security features like Windows Hello and BitLocker encryption.
Microsoft’s “Help Me Choose” tool can simplify your decision-making process by identifying the right device for your needs. Additionally, some retailers offer trade-in programs to offset the cost of new equipment.
3. Transition to alternative operating systems.
For cost-conscious businesses or those seeking open-source alternatives, exploring systems like Linux or ChromeOS Flex can be worthwhile:
- Linux is free, robust, and highly customizable but has a steeper learning curve.
- ChromeOS Flex, a lightweight version of ChromeOS, is ideal for older hardware but may lack compatibility with some business-specific apps.
Before switching to a new operating system, evaluate its impact on your existing workflows and software needs.
4. Leverage extended security updates (ESU).
For businesses requiring more time to transition, Microsoft offers an Extended Security Updates (ESU) program. For $30 per device in the first year, ESU provides critical security updates for Windows 10. While this is not a long-term solution, it can serve as a temporary safeguard.
How to Migrate Before the Deadline
A smooth migration strategy requires adequate time for planning and execution. By acting now, small business owners can avoid the last-minute scramble that often leads to rushed decisions and unforeseen costs. Key steps to take next:
1. Assess your hardware. Run a device-wide compatibility check to identify which systems can be upgraded and which require replacement.
2. Set a migration budget. Account for new device purchases, software licenses, or extended security programs in your budget planning.
3. Consult IT professionals. If managing the transition feels overwhelming, seek help from IT consultants who can assist in developing a customized migration plan.
4. Train your team. Help your employees get acquainted with new systems to ensure a seamless adjustment period.
Staying Secure and Ready for the Future
Transitioning to a new, more secure OS may seem like an unnecessary expense at a time when tariffs and inflation are already straining small businesses. However, the cost of doing nothing is far greater.
