If your business is still using Windows 10, it’s time to start planning for a change. From 14th October 2025, Microsoft will officially end support for Windows 10. That means no more updates, no more fixes, and no more technical support.
While that might sound like a routine product cycle, the impact on businesses can be anything but minor. Running an unsupported operating system can leave you exposed to security threats, reduce your operational efficiency, and even put you out of compliance with key regulations.
Let’s break down what this really means — and how to prepare your business for a smooth, future-proof transition.
Why is Windows 10 End of Life a Big Deal?
When Microsoft ends support for an operating system, it stops releasing:
- Security patches
- Performance and reliability fixes
- Technical support, including online help and updates
While your devices won’t suddenly stop working, continuing to use Windows 10 after the deadline comes with growing risks that could affect your entire business.
1. Cyber Security Risks Will Increase
One of the biggest concerns with running out-of-date software is the growing vulnerability to cyberattacks.
Without regular security updates, your systems will no longer be protected against new threats. Attackers often target known vulnerabilities in older operating systems — and once support ends, any newly discovered weaknesses in Windows 10 won’t be patched.
If your business handles client data, financial information, or relies heavily on digital infrastructure (as most do), continuing with an unsupported OS puts you at serious risk of malware, ransomware, and data breaches.
Even if you have antivirus software in place, outdated systems make it harder to maintain a strong security posture across your network.
2. You Could Fall Out of Compliance
Many businesses today are subject to regulatory compliance requirements — from GDPR and ISO standards to industry-specific frameworks in finance, legal, and healthcare.
Most of these standards require businesses to keep their systems up to date. If your organisation is using unsupported software, you could be in breach of those requirements. That could impact your ability to bid for contracts, pass audits, or demonstrate good data governance to clients and regulators.
If you’re aiming to achieve or maintain compliance certifications, an upgrade to a supported operating system like Windows 11 is essential.
3. Performance and Productivity Will Likely Suffer
Older operating systems are more likely to run into compatibility issues with new applications, cloud tools, and hardware. Over time, you may find that business-critical software simply stops working — or starts performing slowly and unreliably.
As Microsoft and third-party developers shift their focus to newer platforms, Windows 10 will no longer be optimised for the tools your team uses every day. That can lead to slow performance, frequent crashes, or annoying workarounds that chip away at your team’s productivity.
In short: unsupported systems don’t just pose a security risk — they actively hold your business back.
What Should You Do Now?
The good news is that you have time to plan — but not as much as you think. The deadline may be in October, but upgrading your systems can take time, particularly if you need to replace hardware, test software compatibility, or implement cloud-based alternatives.
Here are the key steps to take:
Assess Your Current Setup
Start by auditing your current devices. Not all hardware will support Windows 11, so it’s important to check compatibility.
Older laptops and desktops may not meet the system requirements for the upgrade — in which case you’ll need to decide whether to replace them or explore alternative solutions.
Consider Sustainable Upgrade Paths
Replacing all your devices isn’t always the most cost-effective — or environmentally friendly — approach. If your business is sustainability-minded (or just budget-conscious), there are smarter alternatives to a wholesale hardware refresh.
For example, virtual desktops allow your team to access a secure Windows 11 environment from lower-spec machines. We can also help extend the life of your current hardware by refurbishing and repurposing devices where possible, rather than sending them straight to landfill.
At Dial A Geek, we work with organisations to find greener IT solutions that reduce e-waste and energy consumption — all without compromising performance.
Move to Windows 11 (Strategically)
If your devices are compatible, don’t just hit “upgrade” and hope for the best. A well-managed migration includes:
- Backing up data and applications
- Testing software compatibility
- Rolling out changes in stages to reduce disruption
- Providing training or support for users adapting to the new interface
Our team ensures upgrades are smooth and stress-free, so your business stays online and operational throughout the process.
Strengthen Your Cyber Security Setup
The transition to Windows 11 is the perfect time to review and improve your cyber security strategy. This includes:
- Implementing multi-factor authentication
- Reviewing user access controls
- Ensuring firewalls and antivirus tools are up to date
- Considering endpoint detection and response tools for added protection

Don’t Wait Until the Last Minute
Many businesses leave these transitions too late and find themselves scrambling to upgrade under pressure — often at a higher cost, with greater disruption.
By planning now, you’ll have the flexibility to explore your options, choose the best-fit solutions, and roll them out in a way that minimises downtime. You’ll also avoid potential supply chain issues or inflated prices that can arise closer to the deadline.
Whether you choose to upgrade devices, move to the cloud, or adopt hybrid solutions, getting ahead of the change means fewer headaches — and a more resilient business setup.
