Windows 10 end of support: Why your business should start planning now

14th October 2025 marks a significant milestone in the Microsoft world - the end of support for Windows 10. Is your business prepared for the transition?

For many businesses in the UK, Windows 10 has been a reliable workhorse for the past decade. But as with all technology, its life is coming to an end. From 14th October 2025, Windows 10 will no longer receive regular security updates, bug fixes or technical support. This creates potential vulnerabilities for any organisation still using the operating system after this date.

What does "end of support" actually mean?

When an operating system reaches its end of support date, the manufacturer (in the case Microsoft) stops providing:

Security patches: no more updates to protect against newly discovered vulnerabilities
Bug fixes: existing issues will stay unsolved
Technical assistance: no more help from Microsoft if you encounter problems
Feature updates: no new capabilities or improvements

While your computers won't suddenly stop working on 15th October, they will become increasingly vulnerable to security threats and compatibility issues as time goes on.

The security risks of staying on Windows 10

Continuing to use Windows 10 after support ends exposes your business to a few serious security concerns:

Unpatched vulnerabilities
Maybe the most significant risk is that newly discovered security vulnerabilities will remain unpatched. Cyber criminals often specifically target outdated systems, knowing they contain exploitable weaknesses that will never be fixed.
Compliance issues
For businesses in regulated industries, running unsupported software may breach compliance requirements such as GDPR, potentially leading to fines and reputational damage. Many cyber insurance policies also require businesses to be running supported software, meaning your coverage could be invalidated.
The"zero-day forever" problem
Any vulnerabilities discovered after end of support become permanent security holes, sometimes called "zero-day forever" vulnerabilities because they'll never be patched. These can give attackers persistent access to your systems.
Supply chain risks
As software vendors stop testing their applications on Windows 10, you might find that new versions of critical business software no longer work properly - or at all - on your outdated operating system.

Why early planning is essential

With October 2025 still ahead of us, it might be tempting to delay planning your upgrade strategy. However, leaving your migration to the last minute creates unnecessary risks and pressures:

Limited IT resources

As the deadline approaches, demand for IT support with Windows 11 migrations will increase dramatically. Starting early ensures you have access to the expertise you need without paying premium rates.

Hardware compatibility

Not all devices currently running Windows 10 will support Windows 11. Microsoft's system requirements are more stringent, particularly regarding processor specifications, TPM 2.0 capability, and secure boot functionality. An early assessment lets you budget for necessary hardware replacements as part of your normal refresh cycle rather than as an emergency expense.

Learning curve

Windows 11 brings a few interface changes that require some adjustment from the people using it. Rolling out gradually gives your team time to adapt without impacting productivity.

Testing period

Every business has unique applications and workflows. Early deployment to a test group lets you identify and address compatibility issues before they affect your entire organisation.

Key benefits of Windows 11 for businesses

The upgrade to Windows 11 isn't just about avoiding security risks; it offers many advantages that can benefit your business:

Enhanced security features

Windows 11 was built with security at its core, including:

Hardware-based isolation: creates a secure environment for sensitive data
Microsoft Defender: improved antivirus and anti-malware protection
TPM 2.0 requirement: ensures hardware-level security features are available

Improved productivity

Several features make daily tasks more efficient:

Snap layouts and snap groups: organise your windows and apps for better multitasking
Streamlined interface: cleaner, more intuitive design reduces distractions
Focus sessions: built-in tools to improve concentration and reduce interruptions

Better remote work support

With hybrid working now a mainstream, Windows 11 provides:

Enhanced Microsoft Teams integration: seamless communication built directly into the operating system
Improved virtual desktop functionality: better separation between work and personal computing
Optimised performance for video conferencing: less strain on system resources means smoother meetings

Future-proofing with AI integration

Windows 11 is designed to leverage artificial intelligence capabilities:

Windows Copilot: an AI assistant that helps with various tasks across the operating system
AI-enhanced performance management: intelligently allocates system resources based on usage patterns
Smart applications predictions: anticipates which apps you'll need before you open them

Creating your Windows 11 migration strategy

A successful transition needs careful planning:

Audit your current environment: identify all devices running Windows 10 and assess their Windows 11 compatibility
Prioritise critical systems: determine which systems should be upgraded first, based on importance and security requirements
Budget appropriately: factor in potential hardware upgrades, training costs, and IT support
Create a realistic timeline: work backwards from October, leaving buffer time for unexpected issues
Develop a testing plan: identify a pilot group to test Windows 11 with your business apps before full deployment
