Windows 11 vs Windows 10: What’s Really Different for Business Users?

If your business is still running Windows 10, you’re not alone. Many UK small businesses have stuck with what works — and let’s be honest, Windows 10 has been a reliable workhorse. But with Microsoft now pushing Windows 11 more actively (and support for Windows 10 ending in 2025), it’s time to look at what’s actually different.

Is Windows 11 really worth the upgrade? Or is it just a shinier version of what you already have? Let’s break it down in plain English so you can make a clear, confident choice for your business.

For many small business owners, the thought of a full Windows upgrade brings one thing to mind – disruption. New interfaces, compatibility worries, downtime, retraining… it’s a lot.

Add to that the endless stream of updates and changes from Microsoft, and it’s understandable why many teams have taken a “wait and see” approach.

But with Windows 10 support officially ending on 14 October 2025, businesses that delay too long risk running unsupported systems – which means security gaps, compliance issues, and increased downtime risk.

So, the key question isn’t just “should we upgrade?” but “what do we actually gain (or lose) if we do?”

Windows 11 builds on Windows 10’s core, but it brings several practical improvements – particularly around security, productivity, and user experience.

Here’s what stands out for business users:

1.      Stronger Security by Default
   Windows 11 requires Trusted Platform Module (TPM) 2.0, which adds a hardware layer of protection against tampering and malware. It also enforces Secure Boot and Virtualisation-Based Security (VBS).
   In plain terms: it’s much harder for hackers or viruses to get deep into your system.
   
   
2.       Cleaner, Simpler Interface
   The Start menu has moved to the centre (yes, a bit like a Mac). It’s designed to be less cluttered and easier to navigate – ideal for hybrid working setups where speed matters.

3.       Better Multitasking with Snap Layouts
Windows 11 introduces “Snap Layouts”, letting you neatly organise multiple windows on screen with one click – perfect for anyone juggling spreadsheets, Teams calls, and emails.

4.       Deeper Microsoft Teams Integration
Teams is built directly into the taskbar, making it faster to start meetings and chats. No more hunting for the app or waiting for it to load.

5.       Smarter Performance and Power Management
Windows 11 is optimised to run more efficiently on modern processors, which can mean faster boot times and better battery life for laptops.

Here’s where things get tricky.

Not all PCs that run Windows 10 can handle Windows 11. The new system has stricter hardware requirements – particularly the need for TPM 2.0 and newer processors (Intel 8th Gen or AMD Ryzen 2000 and above).

If your hardware is more than five years old, it may not qualify for the upgrade. That means you might need to plan for hardware refreshes as part of your migration strategy.

The good news? New business-grade laptops and desktops are already fully compatible – and if you buy a device now, it’ll likely come with Windows 11 pre-installed.

Think of Windows 11 as a refreshed office space. The walls are the same, but the layout’s been optimised, the locks are stronger, and the lighting’s better. You can work more comfortably and securely, even though it still feels familiar.

A few data points worth noting:

• Microsoft claims Windows 11 devices show 25% better performance in Microsoft Edge and up to 15% longer battery life on laptops compared to Windows 10.

• According to industry surveys, over 60% of small businesses plan to move to Windows 11 before the 2025 deadline, largely due to security and compliance needs.

For comparison, the transition from Windows 7 to 10 was more disruptive – this one’s smoother because apps and management tools (like Microsoft 365, Intune, and Azure AD) work almost identically on both systems.

Upgrading isn’t just about keeping up appearances — it’s about staying secure, supported, and productive.

Here’s what your business gains:

• Futureproof security – Windows 11’s hardware-based protections are built to defend against today’s ransomware and phishing attacks.

• Improved user experience – Staff spend less time hunting through menus and more time getting work done.

• Better support lifecycle – You’ll get regular updates and security patches beyond 2025.

• Smoother integration with modern tools – Microsoft 365, OneDrive, Teams, and cloud services all run more efficiently.

Positive perception – Clients and partners notice when your business runs up-to-date systems — it shows you take reliability and security seriously.

If you’re still on Windows 10, here’s a simple roadmap to get you sorted:

1.      Check device compatibility
   Use Microsoft’s “PC Health Check” tool to confirm if your current devices can run Windows 11.

2.       Audit your key software
Make sure critical apps (like accounting or CRM tools) are compatible. Most modern ones already are, but double-check with your suppliers.

3.       Plan phased upgrades
Don’t rush. Start with a few test machines, iron out any issues, and roll out in batches. This reduces downtime and training needs.

4.       Back up before upgrading
Always have reliable backups of all data — whether via OneDrive, local drives, or a managed backup service.

5.        Get IT support involved early
Whether in-house or outsourced, having professionals manage the migration ensures licences, drivers, and security settings are configured correctly.

Windows 11 isn’t a dramatic overhaul — it’s a smarter, more secure evolution of Windows 10. For most UK businesses, the upgrade will bring better security, smoother productivity, and peace of mind knowing you’re supported beyond 2025.

If your current PCs meet the requirements, upgrading is well worth planning now. And if they don’t, this might be the perfect time to modernise your devices and simplify your IT setup.
