Don’t Wait Until It’s Too Late… Windows 10 Support Ends Soon!

Upgrade to Windows 11 Before 14 October 2025

That’s when Microsoft will officially end all support for Windows 10, including security updates, patches, and technical assistance.

Continuing to run it after that date isn’t just outdated – it’s a serious cyber security risk.

Running an unsupported OS is like leaving the door unlocked!

With no security patches, updates or vendor support, one vulnerability could bring your entire business to a standstill – or even put it in the ground!

Security vulnerabilities

with no patches available.

Loss of regulatory compliance

(GDPR, Cyber Essentials).

Downtime risks

from unsupported software and apps.

Insurance implications

for using EoL software.

Hardware compatibility limits

that can delay future upgrades.

According to the British Chambers of Commerce, 93%of businesses that suffer extended data loss — longer than 10 days — file for bankruptcy within a year!

Why this matters to your business

According to the UK Government’s Cyber Security Breaches Survey 2024,

50% of small businesses

reported a cyber security breach or attack in 2024.

£1,205 average cost of a breach

The average cost of a breach among small firms was £1,205 — a figure that rises quickly if downtime or data loss is involved.

36% negative impact

36% of those affected said breaches had a negative impact on staff time and ability to operate.

Compatibility Checklist

Here’s some practical advice and technical specs to help you know where your business is in preparing for Windows 11:

Inventory Devices

Use a simple script or tool to identify every PC still running Windows 10. Check and record the…

  • Age of device
  • Processor model (Windows 11 requires specific CPUs)
  • RAM (4 GB minimum)
  • TPM version (TPM 2.0 required)

Moon tip: Use Microsoft’s PC Health Check Tool to see if each machine is eligible.

Assess Compatibility

Many Business PCs bought before 2019 may not be compatible, so make sure to check existing hardware against the minimum requirements of Windows 11:

  • CPU: 8th Gen Intel / Ryzen 2000 or newer
  • RAM: 4 GB+
  • TPM 2.0 chip enabled
  • Secure Boot capable
  • UEFI firmware

Moon tip: Older devices may not be upgradeable, and forcing it risks compliance and support issues – so just don’t try it.

Plan for Replacement or Upgrade

Replace non-compliant devices — don’t patch up old hardware and plan a phased Windows 11 rollout with minimal disruption.

Moon tip: If you need to replace hardware, look for business-grade laptops/desktops with Windows 11 Pro pre-installed and long-term support options.

Back Up Critical Data Before Any Upgrade

Ensure you have full backups of every user’s files, your software licenses, and key configurations, as there’s a chance upgrading the OS could wipe your devices.
Moon tip: Double check you have a Cloud Backup or at least all business-critical files backed-up on external drives at the very least.

Check Line-of-Business Software Compatibility

Verify that your key applications (e.g., finance, design, legacy ERP) will run smoothly on Windows 11.
Moon tip: If there’s any uncertainty, check their websites for compatibility guides and don’t be afraid to contact vendors if need be – if your software won’t work on Windows 11 then you need to know!

Prepare Staff

  • Inform employees about the change.
  • Provide short guides or video training if needed (new interface, snap layouts, etc.).
  • Set expectations for minimal downtime.
Moon tip: Use the Staff Communication Email Template in our Readiness Toolkit to make educating staff about the transition even easier.
