73% of UK Schools Still Use Windows 10 – Here’s Why That’s a Big Problem

Windows 10 Is Ending – And Time Is Running Out

The Windows 10 end of support date is set for 14 October 2025 — after that, Microsoft will stop providing security updates, patches and technical assistance, even for schools. This looming deadline poses a serious risk for education institutions still relying on the ageing operating system.

According to Microsoft’s own data, Windows 10 is currently used in over 73% of UK education devices.

The challenge for schools?

• Time: Upgrading takes months to plan, especially across multiple sites or Trusts
• Budget: Delayed planning could mean last-minute costs
• Security: Unsupported systems become vulnerable to threats — fast

 

The Risks of Doing Nothing

Sticking with Windows 10 beyond the support cut-off is not a neutral choice. It introduces a series of knock-on effects, including:

• Exposure to malware and ransomware attacks
• Potential breaches of GDPR due to outdated security
• Loss of compatibility with essential education software
• Higher long-term costs from reactive upgrades or unsupported devices

 

Multiple Providers = Multiple Headaches

Many schools rely on a mix of IT contractors, hardware resellers and software suppliers. This often leads to:

• Unclear accountability when something fails
• Misaligned timelines between procurement, installation and training
• Inconsistent advice, sometimes leading to poor purchasing decisions

When each provider works in isolation, schools are left to join the dots — and carry the risk.

Sticking with Windows 10 increases exposure for schools to malware and ransomeware attacks  

 

A Joined-Up Approach Makes Sense

Schools that have already started their transition report smoother roll-outs when a single supplier takes the lead. It improves efficiency, reduces pressure on internal IT teams, and ensures better coordination across the project.

The right support from Clarion can help schools:

• Audit existing devices for Windows 11 compatibility
• Plan phased upgrades that suit term-time schedules
• Identify sustainable and cost-effective device disposal options
• Maintain continuity of service throughout the process

The end goal isn’t just new software — it’s a resilient, secure and manageable IT environment.

 

Don’t Miss the Window

With 2025 fast approaching, schools should now:

1. Begin a site-wide audit of Windows 10 devices
2. Review compatibility and licensing options for Windows 11
3. Start conversations with trusted IT providers about upgrade pathways
4. Consider environmental responsibilities around device disposal

Schools need time to make these changes properly. Starting now avoids rushed decisions and reduces the risk of summer-term disruption.
