As the October 14, 2025, end of support deadline for Microsoft’s Windows 10 support draws closer, millions of users must prepare for a significant transition.
What does this mean ?
Effectively Microsoft will stop producing regular security updates and improvements for machines using Windows 10. Following this move the likelihood of your Windows 10 machine becoming vulnerable and a big target for criminals is extremely likely. Readily available applications on the internet can already be queried to find vulnerable equipment and systems – all it will take is someone to as for a list of Windows 10 machines and a list of vulnerable devices is created for them target.
How do I protect myself ?
Moving to a supported operating system is not just about accessing new features—it's about maintaining security, operational continuity, and compliance.
But in some cases it may not be just an upgrade of our operating system, as with most things, the newer versions make use of newer and safer technologies and in certain cases means the hardware (actual computer) may need to be replaced.
Microsoft have produced a free to use tool which will assess the compatibility of your computer with the W11 operating system.
Why should I upgrade ?
Keeping software updated is a cornerstone of cybersecurity. Updates, particularly security patches, protect against newly discovered vulnerabilities. However, even more crucial is ensuring your software is actively supported. Without official support, updates stop altogether, leaving systems exposed to exploitation.
What happens if you don’t upgrade?
Whilst there will be a limited option for extended support for W10 after 14th October 2025 this comes at a premium. It is only available to eligible customers through the Microsoft ESU (Extended Support Updates) program. This is a paid for service at $61 per device, per year, for corporate users.
This is presently only being offered as a 3-year extension.
Failing to upgrade after support ends could have severe consequences:
- Increased Vulnerabilities: New weaknesses in Windows 10 will remain unpatched, making systems prime targets for exploitation.
- Data Breaches and Malware: Unsupported systems are more susceptible to cyberattacks, including ransomware and spyware.
- Business Risks: Organisations risk financial loss, reputational damage, and possible regulatory penalties.
- Business software may surpass the ability to operate on W10 as it also upgrades and patches.
Upgrading to a supported OS ensures regular updates, bolstering your system’s defence against evolving threats and maintaining optimal performance and security.
Why start preparing now?
Transitioning to Windows 11 isn’t a task to be left until the last minute. It requires thorough planning to address potential technical, operational, and security challenges. Early preparation minimises disruption and ensures a seamless transition.
Plan for legacy dependencies
Just as current business software updates may impact operation on legacy W10 systems, then equally existing applications should be reviewed for compatibility with W11 and appropriate decisions considered. Many organisations rely on applications or technologies that were designed specifically for Windows 10. These legacy dependencies may not be compatible with Windows 11. Keeping certain machines on Windows 10 might seem like a quick fix, but it introduces significant risks:
- Unpatched Systems: Unsupported machines will lack security updates, becoming easy targets for attackers.
- Operational Inefficiencies: Relying on outdated software could hinder your ability to adopt new, more secure technologies.
If your organisation depends on legacy systems, now is the time to assess your options. Identify alternatives, consider modernisation strategies, or find ways to phase out outdated technologies.
Allocate time for training
A shift to Windows 11 involves more than just a technical upgrade; it may require operational adjustments and staff training. While Windows 11 offers familiarity to long-time users, some employees might need time to adapt to the new interface and features.
- Proactive Training: Provide hands-on experience and training to ensure a smooth transition.
- Avoid Productivity Loss: Early preparation helps mitigate potential dips in productivity during the changeover.
Next Steps: Preparing for the Future
The end of Windows 10 support is more than a deadline—it’s a call to action. Here’s how to get started:
- Inventory Your Systems: Identify all devices still running Windows 10.
- Evaluate Compatibility: Check the compatibility of applications and hardware with Windows 11.
- Create a Migration Plan: Develop a timeline for upgrades, staff training, and decommissioning legacy systems.
- Communicate the Change: Keep employees informed about the transition and its benefits.
- Leverage Support Services: Partner with IT providers to ensure a smooth migration process.
Taking proactive steps now will help you avoid the risks of running unsupported systems and position your organisation for future success.
