On 14 October 2025, Microsoft will officially end support for Windows 10, marking a major milestone for businesses still relying on this operating system. While your computers won’t suddenly stop working, the risks of staying on Windows 10 after this date grow significantly — from increasing cyber security vulnerabilities to compliance issues for businesses in regulated industries.
At Coltek I.T., we are committed to ensuring Colac businesses have the information, tools, and IT support needed to make a smooth transition to Windows 11. This guide outlines the key changes, risks, and practical steps you can take to prepare your business before the deadline.
What Happens When Windows 10 Support Ends?
From 14 October 2025 onwards, Microsoft will no longer provide:
- Free security updates to fix newly discovered vulnerabilities.
- Bug fixes or performance enhancements.
- Technical support from Microsoft.
Although your devices will still run, they will become increasingly vulnerable to cyber threats, including malware, ransomware, and data breaches. Over time, you’ll also find it harder to run newer software or connect to updated devices and peripherals, leading to compatibility issues.
Why Windows 11 is the Smart Upgrade
Windows 11 is Microsoft’s most secure and modern operating system, designed to meet the needs of today’s businesses. Upgrading offers several benefits that go beyond just security patches:
1. Enhanced Security Features
Security is built into Windows 11 at a hardware level, with features like Secure Boot, advanced encryption, and TPM 2.0 (Trusted Platform Module) support. These tools help prevent unauthorised access and data theft, giving businesses a more resilient IT environment.
2. Modern, Intuitive Interface
The cleaner design and improved navigation help employees work more efficiently, whether they’re in the office, working remotely, or out visiting clients. Simple tools like Snap Layouts make multitasking easier, while the updated Start Menu helps users find what they need faster.
3. Performance Optimisation
Windows 11 has been fine-tuned to make the most of modern hardware, offering faster boot times, smoother performance, and better battery life for laptops.
4. Cloud and Collaboration Features
With deeper integration with Microsoft 365 and OneDrive, businesses using Windows 11 can easily access files from any device, collaborate with team members in real-time, and protect critical data with cloud-based backup solutions.
How to Know if Your Current Devices Are Ready for Windows 11
Microsoft has set minimum hardware requirements for Windows 11. Some older machines might not meet these standards, meaning they won’t be eligible for an upgrade.
Minimum System Requirements for Windows 11:
- 1GHz 64-bit processor with at least 2 cores
- 4GB of RAM
- 64GB of storage
- TPM 2.0 chip
- Secure Boot capable firmware
- DirectX 12-compatible graphics card
If your current hardware doesn’t meet these requirements, you will need to consider hardware upgrades or replacement devices.
At Coltek I.T., we can run an IT assessment across your organisation to check your fleet’s compatibility and recommend an IT roadmap to ensure your technology is ready for Windows 11.
The Risks of Staying on Windows 10
Continuing to use Windows 10 after support ends exposes your business to significant risks, including:
1. Increased Security Threats
Without regular security updates, your systems become an easy target for cyber threats like ransomware, malware, and data theft.
2. Compliance Issues
For industries like healthcare, finance, and NDIS service providers, running unsupported software may breach industry standards and data protection regulations, leading to fines or legal action.
3. Software Compatibility Problems
Newer software applications will eventually stop supporting Windows 10, leaving you unable to use the latest business tools or access new features.
What if My Business Can’t Upgrade Yet?
If your business relies on legacy applications or specialised hardware that’s not compatible with Windows 11, there are still options:
- Explore cloud-hosted solutions where possible to reduce reliance on local hardware.
- Segment outdated systems onto isolated networks to limit security exposure.
- Implement enhanced endpoint protection for devices running older software.
- Discuss temporary options for extended support (if Microsoft offers them closer to the 2025 deadline).
We can work with you to identify the best approach that balances security, performance, and cost.
Don’t Leave It Too Late
While October 2025 might sound far off, upgrading an entire organisation — particularly those with custom software, remote workers, or complex systems — takes time. Planning ahead ensures:
- Minimal disruption to daily operations.
- Staff training is provided where necessary.
- Your data remains fully protected during the transition.
- You avoid any last-minute rush when everyone is scrambling to upgrade.
