With Windows 10 reaching its end of life on 14 October 2025, you might be wondering what will happen if you don’t upgrade to Windows 11 as a business? Short answer is that sticking with it could expose your business to serious risks. So, what happens if you don’t upgrade to Windows 11? Let’s break it down.
Windows 10 End of Life: What It Really Means
When Microsoft announces an operating system’s end of life, it’s not just a suggestion to upgrade. It’s a clear warning. After 14 October 2025, Microsoft will no longer provide security updates, patches, or technical support for Windows 10.
While your computers won’t suddenly stop working, they will become increasingly vulnerable to cyber threats and other issues. Without regular security updates, cyber criminals can exploit weaknesses, and you may find that newer software stops functioning properly on outdated systems.
What Issues Will We Face If We Don’t Upgrade to Windows 11?
Sticking with Windows 10 after its end of life will create several challenges.
Cybersecurity Threats
One of the biggest risks of staying on Windows 10 is the lack of security updates. Cybercriminals actively search for weaknesses in outdated systems, making your business an easy target for malware, ransomware, and other attacks. Without ongoing protection, your sensitive business data could be compromised.
Compliance and Legal Risks
If your business handles customer data, compliance with GDPR and other security regulations is crucial. Using an unsupported operating system could put you in breach of legal requirements, leading to fines, reputational damage, and even loss of business contracts.
Software and Performance Issues
As software developers focus on Windows 11, many applications will stop being compatible with Windows 10. This can lead to frustrating slowdowns, unexpected crashes, and a decline in productivity. Even web browsers and essential business tools may become difficult to update and use effectively.
Rising IT and Maintenance Costs
Running outdated systems often leads to higher IT costs. Emergency fixes, security breaches, and last-minute hardware replacements can become expensive. Planning an upgrade now allows for a smoother transition and avoids unexpected expenses.
No More Technical Support
After Windows 10’s end of life, Microsoft will no longer provide technical support for issues. If something goes wrong, finding a solution will be harder and likely more expensive, with many IT providers prioritising support for Windows 11 instead.
Will Windows 10 Stop Working if I Don’t Upgrade to Windows 11?
No, things won’t suddenly come to a halt. Windows 10 will continue to function after its end of life, but it will no longer receive security updates or support from Microsoft.
While your computer won’t shut down overnight, the lack of updates means you’ll be using an increasingly vulnerable system. Over time, performance issues, software incompatibility, and security risks will make it impractical to keep using Windows 10 for business operations.
Without updates, any security flaws discovered after October 2025 will remain unpatched, making it easier for hackers to target your system. As new software and applications are developed for Windows 11, Windows 10 users may find that their business-critical tools stop working or experience frequent crashes. Eventually, maintaining Windows 10 will become more costly and problematic than upgrading.
Deciding Whether you Do or Don’t Upgrade to Windows 11?
If you’re uncertain about upgrading to Windows 11, start by assessing your current situation. Ask yourself:
- Are my devices compatible with Windows 11?
- Will my current software and applications work smoothly after the upgrade?
- Can my business afford to risk security vulnerabilities and compliance issues?
If you don’t have the answers (and that’s OK!), consulting an IT provider is your best next step. An IT expert can evaluate your business needs, check your hardware compatibility, and guide you through the upgrade process in a way that minimises disruption.
Waiting too long to decide can leave you scrambling at the last minute, increasing costs and stress. The best approach is to be proactive. Start gathering information now and create a transition plan that ensures your business stays secure and productive.
