Microsoft’s Windows 10 Operating System will no longer receive security updates from 14th October 2025.  For those organisations that currently use Windows 10 this is a significant date as from then onwards their OS will be vulnerable.

From the middle of October, Windows 10 will be classed as ‘legacy’ or ‘end of life’ and remaining software vulnerabilities will become common knowledge for hackers to exploit, even for criminals with low levels of technical expertise. Businesses still using Windows 10 will no longer be compliant with Cyber Essentials, as certification requires organisations to use software that is licensed and supported.

If Windows 10 is your business’s OS, now is the time to start planning for its successor in order to ensure a smooth transition to a supported OS.

Solutions and Alternatives to Windows 10

1. Microsoft is offering an Extended Security Updates program for Windows 10, which means that organisations that choose to continue using Windows 10 after October 14th, will have the option of enrolling their PCs into a paid ESU subscription. The ESU program enables PCs to continue to receive critical and important security updates through an annual subscription service, but there are limitations to the service. Details are available at:

2. Windows 10 Enterprise LTSC: For devices where stability and predictable updates are crucial, such as industrial machines, Windows 10 Enterprise LTSC (Long-Term Servicing Channel) could be a viable option. It provides security updates for a longer period (up to 10 years) but lacks some of the newer features of regular Windows 10 and 11 versions. More details are available at:

3. Windows 11 is Microsoft’s next major operating system, and businesses will need to upgrade to it eventually. It comes with security improvements, performance enhancements, and a more modern user interface.

If your hardware supports it, it makes sense that Windows 11 will be your go-to option, but before committing to it, check whether your current hardware is compatible. Windows 11 has more stringent system requirements than Windows 10, particularly the need for TPM 2.0, Secure Boot, and specific processor generations.

Here’s how to proceed on a PC:

• Run the PC Health Check Tool: Microsoft offers a tool to check whether your device meets the minimum requirements for Windows 11.
• Evaluate Hardware Upgrades: If your devices are nearing end-of-life or cannot support the upgrade, consider refreshing your hardware. Evaluate the cost of upgrading devices versus the long-term benefits of new, more powerful machines that come with extended support.

If Windows 11 is the right choice for you, here’s how to update your OS on a PC:

• Select the start button, then click on Settings.
• Click on Update and Security.
• Select Check for Updates to see if your PC can run Windows 11, or if the upgrade is ready for your PC.

4. Linux: Some businesses may have legacy software or hardware that might not be compatible with Windows 11. Consider other operating systems, such as Linux. Linux distributions can provide long-term support, but migrating to Linux requires specific training and can impact software compatibility.

Decided on your new Operating System? Now develop an Upgrade Plan and Timeline

Planning ahead is key. Waiting until much later in the year is risky, and a rushed transition may result in business disruption. Create a step-by-step migration strategy that includes the following:

• Audit Your Software: Identify all the software your business relies on and verify its compatibility with Windows 11. Legacy applications or specialised software might require updates or replacements.
• Pilot Program: Before rolling out your OS across the organisation, test it on a small group of users. This will help you identify potential issues early, such as compatibility problems or workflow disruptions.
• Timeline for Full Migration: Set clear milestones for when different departments or teams will transition to the new system. Aim to have most users migrated before the end of 2025.

Ensure Security and Compliance Readiness (Windows 11)

• Windows 11 Security Features: Windows 11 offers advanced security features, including hardware-based isolation, secure boot, and improved ransomware protection. These can enhance your organisation’s defence against modern cyber threats.
• Regular Updates: Once on Windows 11, ensure that automatic updates are enabled to receive the latest patches and updates from Microsoft.
• Backup and Recovery: Before migrating, ensure that your data is backed up. Having a disaster recovery plan in place will help you recover quickly in case of migration issues.

Provide Employee Training and Support (Windows 11)

A smooth transition goes beyond technology—it also involves people. Windows 11 introduces a new interface and features that might require some adaptation. To ensure productivity isn’t hindered during the transition:

• Training: Provide your employees with training materials or workshops that help them get acquainted with the new system. Focus on key changes like the new Start Menu, multitasking features, and security enhancements.
• Ongoing Support: Offer ongoing IT support to help with any technical issues or questions your employees may have as they adjust to the new system.

 Budget for the Upgrade (Windows 11)

The upgrade from Windows 10 to Windows 11 (or another solution) will incur costs. These include:

• Licensing Costs: Windows 11 may require new licenses for some devices.
• Hardware Upgrades: If your devices are incompatible with Windows 11, you may need to invest in new hardware.
• IT Resources: Allocate resources for your IT staff or external consultants to assist with the upgrade process, including testing, deployment, and troubleshooting.

Consider a Cloud-Based Solution

For some businesses, moving to a cloud-based operating system (or integrating with cloud services) may be a compelling alternative. Microsoft’s Azure and other cloud services can provide businesses with secure, scalable environments, reducing the reliance on local machines and streamlining software updates.

 Monitor Post-Upgrade Performance

Once the upgrade is complete, closely monitor system performance and user feedback. This will help identify any lingering issues and allow you to make tweaks to your system for better productivity. Establish a feedback loop with your employees to ensure the transition is as smooth as possible.
