For many businesses, Windows 10 has been the reliable workhorse powering everyday operations. But on the 14th October 2025, that changes. Microsoft will officially stop supporting Windows 10 on this date, meaning they’re ending all security updates, bug fixes, and technical support.
If your business still relies on Windows 10, it’s time to act. The end of life (EOL) can mean a serious cyber security risk and compliance challenge. In this blog, we’ll break down what Windows 10 EOL really means, the dangers of sticking with outdated systems, and how IT support from Redinet can help your business upgrade with confidence.
What Does “End of Life” Actually Mean?
When Microsoft ends support for an operating system, it stops providing:
- Security updates
- Bug fixes
- Technical assistance
- Performance enhancements
This leaves all machines running Windows 10 after the EOL date without defences against newly discovered vulnerabilities. Cybercriminals actively monitor EOL software, knowing these systems will become “easy targets” for attacks like ransomware, data breaches, and credential theft.
Why It’s a Cybersecurity Crisis in Waiting
- Unpatched Systems Are Vulnerable by Design
According to Sophos’ State of Ransomware 2024 report, 32% of cyber-attacks in 2024 originated from unpatched vulnerabilities. We’ve also seen plenty of recent examples of the importance of staying up-to-date, with Apple recently rushing to patch two actively exploited iOS flaws that were being used in sophisticated targeted attacks. Recent insights across cybersecurity news platforms also point to a sharp rise in exploit kits specifically designed for outdated operating systems. These tools automate attacks on known flaws – flaws that will never be fixed in Windows 10 once it’s retired.
Your systems could become an open door to attackers, and because many businesses delay migrations, the exposure window could last months or even years. A single compromised machine could lead to:
- Encrypted or stolen client data
- GDPR violations and legal repercussions
- Costly operational downtime
- Cyber Essentials & Regulatory Compliance at Risk
To achieve Cyber Essentials certification, businesses must prove that all software is supported and regularly patched. After Windows 10 reaches its EOL:
- You won’t be compliant.
- You could fail audits.
- You might lose access to projects requiring government or enterprise cyber security validation.
With increased scrutiny from clients, partners, and regulatory bodies, being non-compliant can impact everything from revenue to reputation.
- Operational Disruption & Reduced Productivity
EOL systems often develop compatibility issues with modern software, slowing workflows or preventing tools from working altogether. You may also face difficulties integrating cloud platforms, remote tools, or industry-specific applications that no longer support Windows 10.
When systems underperform, your team does too – affecting customer experience, collaboration, and profitability.
So What Should You Do Now?
Proactive planning is the only way to avoid a last-minute scramble that could cost your business time, money, and cybersecurity integrity. Here’s how to get ahead of the curve:
Complete an IT Asset Audit
Start by identifying every device still running Windows 10. Then, assess:
- Compatibility with Windows 11
- Role in business-critical operations
- Whether temporary alternatives (like Microsoft’s Extended Security Updates) might be needed
This audit also helps uncover outdated or unnecessary devices that could be decommissioned, reducing overhead and attack surface.
Create a Migration Plan
Work with your IT provider or internal team to design a phased rollout of Windows 11. Consider:
- Prioritising high-risk or high-privilege machines first
- Budgeting for licenses, training, or new hardware
- Scheduling rollouts outside of busy business periods
A staged approach minimises disruption while maximising control and oversight.
Link Migration to Your Cybersecurity Roadmap
Don’t treat this as “just another update.” Use it as a moment to align your broader security objectives with tools like:
- Cyber Essentials certification
- Enhanced endpoint protection
- Multi-factor authentication
- Secure backup systems
The more you build into your migration strategy now, the stronger and more compliant your infrastructure will be for years to come.
