Windows 10 Support Ends: 14 October 2025
Microsoft will officially end support for Windows 10 on 14 October 2025. After this date, no security updates, bug fixes or technical support will be provided. For UK SMEs, this has serious implications for cybersecurity, compliance, and operational reliability.Planning ahead now is essential.
What Does "Windows 10 End of Life" Actually Mean?
When an operating system reaches End of Life, it no longer receives security patches or support from Microsoft. That means new vulnerabilities discovered after 14 October 2025 will remain unpatched — increasing the risk of cyberattacks, data breaches and downtime.
Key Changes After 14 October 2025
Once Windows 10 is out of support:
- No more security updates – New threats won't be fixed
- No Microsoft support for issues or failures
- No new features or performance improvements
- Software compatibility will decline over time as vendors move on
For businesses, this makes Windows 10 increasingly risky to run as part of your IT estate.
The Risks of Staying on Windows 10 for UK SMEs
Remaining on Windows 10 after support ends is technically possible — but risky. Here are the main issues:
Increased Cybersecurity Threats
Unsupported systems are prime targets for cybercriminals. Attackers actively scan for outdated software because vulnerabilities remain open indefinitely. The 2017 WannaCry attack exploited unpatched Windows systems, causing widespread disruption across the NHS and UK organisations.
Compliance Challenges
GDPR expects 'appropriate technical measures' to protect data — outdated software rarely qualifies. Cyber Essentials certification requires supported operating systems. For organisations working with government, education or regulated sectors, this may block contracts.
Software & App Compatibility Issues
Software vendors are phasing out Windows 10 support. Expect applications not updating correctly, integration failures, reduced performance and user frustration as modern apps become Windows 11 only.
Cyber Insurance Limitations
Many cyber insurance policies now include clauses around supported systems. If a breach occurs on an unsupported OS, insurers may reduce or refuse cover if outdated systems contributed to the incident.
Should You Pay for Windows 10 Extended Security Updates (ESU)?
Microsoft is offering Extended Security Updates (ESU) for Windows 10, but only as a temporary measure. This provides security updates only — not features or support.
UK Price Guide (per device)
Year 1 is around £45 per device, and it increases each year. ESU may be suitable if you need more time to replace hardware or rely on a critical application not yet compatible with Windows 11.
For most SMEs, ESU is a short-term safety net, not a long-term solution.It's better to plan a proper Windows 11 migration that future-proofs your business.
How to Upgrade from Windows 10 to Windows 11 with Minimal Disruption
A well-planned upgrade avoids downtime and user frustration. At Osiris IT, we use a staged, low-risk approach:
Device & Hardware Readiness Check
We assess which devices are compatible with Windows 11 and create a plan for upgrades or replacements where needed.
Data Backup & Protection
Before any changes, we take full backups to ensure data is secure and recoverable.
Staged Deployment
We roll out upgrades in phases to minimize disruption, with testing at each stage.
Training & Post-Migration Support
We provide user training and helpdesk support to ensure your team feels confident with Windows 11.
Why Windows 11 Is Worth the Upgrade for SMEs
Upgrading isn't just about avoiding risk — Windows 11 brings genuine business benefits:
Frequently Asked Questions
Can I continue using Windows 10 after 14 October 2025?
Yes, but it won't be secure or supported, and most organisations will consider it too high-risk for business use.
Is the Windows 11 upgrade free?
The upgrade is free if your device meets the system requirements. If hardware is too old, a replacement device will be needed.
What if my hardware doesn't support Windows 11?
We can help you assess upgrade vs replacement options and source compliant devices through our IT procurement service. Windows 11 requires TPM 2.0, Secure Boot, and specific CPU generations (Intel 8th gen or AMD Ryzen 2000 or newer). Most devices from 2018 onwards are compatible.
How long does a business migration take?
Most small and medium businesses complete the process in 2-4 weeks, depending on the number of devices and complexity. We work in stages, often upgrading outside business hours, and provide temporary support during the transition period.
