|Business Incident Report Plan

Windows 10 ended support on 14th October, 2025. 

Microsoft no longer provides technical assistance, feature updates, or critical security updates. For businesses, this was more than a technology change - it affected cybersecurity posture, compliance, and long-term IT planning.

If your business is still be running Windows 10, here’s what you should be thinking about:

Review and update your Incident Response Plan

Now Windows 10 is out of support, any unpatched vulnerabilities could become targets for attackers. If you are still on Windows 10, it’s essential to review your incident response plan (IRP).

  • Make sure your plan accounts for potential increases in security risks.
  • Consider whether your cyber insurance policies require you to run supported software.

Your IRP should reflect the reality that running an unsupported OS increases exposure and potentially makes cyber insurance invalid.

Evaluate your options for staying supported

Microsoft has provided several paths for businesses:

  • Upgrade to Windows 11 on existing PCs If your devices meet the minimum system requirements, upgrading to Windows 11 is the most straightforward option. It delivers a modern, secure, and efficient computing experience.
  • Invest in new Windows 11 devices If your PCs aren’t eligible, you may need to replace them. New Windows 11 devices also bring performance improvements, energy efficiency, and longer support lifecycles.
  • Enrol in the Windows 10 Extended Security Updates (ESU) programme If you need more time, Microsoft offers ESUs for up to one year after October 14, 2025. This buys you time to plan a migration, but it should not be considered a long-term solution.

Include OS upgrades in your long-term business strategy

Even if you plan to use the ESU programme for a short extension, you should:

  • Incorporate an OS upgrade into your business plan. Budget for new hardware and software well in advance.
  • Align upgrades with other technology initiatives. For example, pairing a Windows 11 rollout with a move to cloud services or enhanced endpoint security solutions.
  • Factor in compliance requirements. Many industries mandate that organisations/suppliers run supported operating systems.

Planning proactively ensures that your business avoids unexpected costs or compliance gaps.

Strengthen security measures

Bolster your defences:

  • Layer in advanced endpoint security solutions.
  • Restrict internet-facing use of Windows 10 devices.
  • Tighten access controls and enforce strong identity management.
  • Increase monitoring and logging for unusual activity.

These measures won’t eliminate risk, but they can help reduce it!
