Why Your Business Must Act Now and Upgrade to Windows 11

With October 14, 2025 approaching fast, Microsoft is drawing a line under Windows 10 support, a moment that carries serious implications for SMEs across the UK. Here at Acora One, we understand that this shift isn’t just a technical timeline; it’s a business imperative.

This blog will guide you through every detail, including important details about Windows 10 such as its features, update policies, and support lifecycle.

From what end-of-support means (technically, operationally, and financially) to a strategic, step-by-step roadmap for moving to Windows 11, let’s walk through what you need to know, and why doing nothing is not an option.

What Is “End of Support” for Windows 10?

End of support means Microsoft will cease providing:

  • Security patches and updates
  • Feature enhancements
  • Technical support

This leaves PCs running Windows 10 susceptible to new cyber threats, increasingly incompatible applications, and obsolete infrastructure.

After October 14, 2025, any computer running Windows 10 will no longer receive security updates or support from Microsoft. Microsoft confirms that, after October 14, 2025, Windows 10 will no longer receive updates of any kind.

Your business exposure: Without regular updates, your systems become vulnerable, non-compliant, and unfit for modern work demands.

What Does Windows 10 End of Support Mean for Your Business?

  • Increased risk of malware and ransomware: Unsupported OS platforms are prime targets for cybercriminals.
  • Compliance and insurance issues: Outdated systems may fail to meet regulatory requirements or insurance terms.
  • Rising costs of maintaining old PCs: ESU (Extended Security Updates) may keep systems functional, but at steep, ballooning costs. To remain supported, devices must install the latest cumulative updates; after end of support, this will no longer be possible.
  • Performance and productivity drag: Software eventually refuses to run on antiquated systems.
  • Environmental impact: Replacing tons of hardware risks a major e-waste spike. Advocacy groups are raising legitimate concerns.

Key message: Running Windows 10 after October 2025 is like leaving your back door open: expensive, risky, and unnecessary.

How Can You Keep Machines That Don’t Qualify for Windows 11?

Extended Security Updates (ESU) offer a bridge—but not a solution:

PCs that enroll in ESU can continue receiving security updates for up to three years, but:

  • Only security fixes: no feature enhancements or technical support, and no feature updates after end of support
  • ESU is not available for certain Windows 10 Enterprise editions, such as those with specific volume licensing; these enterprise editions have separate licensing, support, and update pathways
  • Must be running Windows 10 version 22H2 to qualify
  • Alternative paths, like virtualisation or Windows 365, may offer better value.

Windows 10 LTSC (Long-Term Servicing Channel) remains supported into 2029–2032, but this version is typically reserved for industrial or embedded systems, not general office use.

Will Microsoft 365 and Office Still Work on Windows 10?

Yes… but with caveats:

  • Microsoft 365 apps (subscription): Continued support until 10 October 2028, giving your organisation more time to plan.
  • Non-subscription versions: Office 2016 & 2019 are already out of support on all OS versions. Office 2021 and LTSC 2021 will run on Windows 10 beyond 2025 but are not supported post-2026.

Should You Upgrade Hardware to Meet Windows 11 Requirements?

Minimum Windows 11 requirements include:

  • TPM 2.0, Secure Boot, virtualisation-based security, HVCI, and hardware-enforced stack protection

Driver availability for your hardware is also essential for compatibility with Windows 11. Missing or outdated drivers may prevent a successful upgrade.

While many modern machines already meet these requirements, older PCs may not.

You have a few options:

  • Upgrade components—e.g., TPM modules, more RAM, SSD upgrades
  • Repurpose machines: Use older PCs for non-critical tasks, kiosk setups, or training units
  • Trade-in programmes: Many OEMs offer recycling and part-exchange options

What Can You Do with Old Windows 10 PCs?

  • Donation or internal repurposing: Use them for guest access, offline tasks, or training
  • Recycle responsibly: Use manufacturer-led e-waste programs
  • Retain selected units under ESU temporarily, but plan to phase them out eventually

Why Windows 11 Matters: Designed for Security, Efficiency, and Modern Business

Security you can’t set aside:

  • TPM 2.0, VBS, HVCI, Secure Boot out-of-the-box
  • Smart App Control, Microsoft Defender, memory integrity, and BitLocker encryption
  • Microsoft’s “chip-to-cloud, zero-trust by default” approach drastically reduces firmware and malware threats

Productivity enhancements:

  • Speedier wake, multitasking with Snap Layouts and Virtual Desktops
  • Streamlined UI: centred taskbar gives Microsoft 365 integration a clean, intuitive feel
  • Windows 11 (and Windows 10 before it) includes support for DirectX 12, which enhances gaming and multimedia performance by improving hardware efficiency and graphics rendering.

Accessibility, collaboration, and AI-ready:

  • Accessibility shortcuts, closed captions, and contrast modes bring inclusivity to the fore
  • AI integration, like Recall, Copilot, and live-transcribe, are built into Copilot+ PCs, enhancing productivity with zero learning curve

Choosing the Right Windows 11 Edition

Windows 11 editions:

  • Pro: Includes BitLocker, Enterprise-grade security, ideal for SMEs
  • Enterprise/Education: For larger organisations with advanced IT needs

Windows 11 provides more options for device management, security, and user customization compared to previous editions.

Most SMEs will find Windows 11 Pro ideal, it balances robust security, remote management, and cost.

Windows 11: A Free Upgrade?

Yes, for qualified hardware:

  • Eligible Windows 10 devices will see a free upgrade prompt in Windows Update. In some cases, a valid product key may be required to activate Windows 11 after upgrading from Windows 10.
  • If hardware doesn’t qualify, consider refurbishment or purchasing Windows 11-certified PCs.

A Step-by-Step Plan for Moving to Windows 11

Upgrading your systems isn’t just about staying compliant; it’s about giving your business the tools it needs to thrive.

With Windows 10 approaching its end of support, now is the perfect time to start preparing for the future.

Assessment: Run Microsoft’s PC Health Check across your fleet

Prioritise: Identify urgent replacements versus simple upgrades

Pilot: Test Windows 11 in a controlled group

Train: Educate staff on new features and security procedures

Rollout: Roll out in phases, offering support and feedback channels. When installing Windows 11, ensure you use official Microsoft tools and follow recommended installation procedures for best results.

Maintain: Monitor usage, support issues, and security reporting

Troubleshooting Common Issues During the Upgrade

Upgrading to Windows 11 can sometimes present challenges, but most issues can be resolved with a few targeted steps. If you encounter compatibility issues, installation errors, or problems with drivers, start by opening the PC Settings app and checking Windows Update for the latest updates and fixes. Microsoft regularly releases updates to address known issues, so keeping your device set to receive the latest updates is essential.

If you’re using installation media created with the media creation tool and run into errors, try recreating the media to rule out corrupted files. Make sure you’re using the correct edition and that your device meets all compatibility requirements. Updating your drivers and temporarily disabling any non-essential programs can also help resolve installation or compatibility issues. For persistent problems, consult the Microsoft support website, join the Windows Insider community for early fixes, or visit the Microsoft Store for hands-on assistance.

Always back up your files and settings before starting the upgrade to safeguard your data. By following these troubleshooting steps and leveraging Microsoft’s support resources, you can overcome common upgrade hurdles and ensure your PC is running the latest, most secure version of Windows 11.

Managing Costs and Overcoming Challenges

  • Cost Leak: ESU is a short-term patch—not a sustainable plan
  • Hardware Budget: Seek trade-in deals and staged replacement cycles
  • Skills Gap: Use Copilot helpers or training for staff
  • Environmental Concerns: Use recycling and maximise device longevity
