Why it’s time to move on from Windows 10: A simple guide for business owners

If your business still runs on Windows 10, it’s time to start planning an upgrade. Microsoft ended its support for Windows 10 on October 14, 2025, which means no more free security updates or technical fixes.

According to the UK’s National Cyber Security Centre (NCSC), staying on unsupported systems exposes your business to unnecessary risk - and upgrading to Windows 11 is the smarter, safer move.

 

What Happens After October 2025?

 

Now the deadline has passed, Windows 10 machines will still switch on, but they’ll become increasingly vulnerable. New security flaws won’t be patched, and cybercriminals know it. Insurers and regulators may also view unsupported systems as non-compliant, which could affect your coverage or contracts.

 

Why Windows 11 Is More Secure

 

Windows 11 isn’t just a new look - it’s built with modern security at its core. It requires hardware features like TPM 2.0 and Secure Boot, which help stop malware and protect business data.

With tools such as BitLocker encryption, Credential Guard, and zero-trust protections, Windows 11 offers a stronger defence against today’s cyber threats.

 

The NCSC recommends using Windows 11 on approved hardware to ensure these features work properly - and to use the upgrade as a chance to review your overall IT security.

What Your Business Should Do Now

 

  1. Check your devices - see which ones can run Windows 11.

  2. Plan your rollout - start with a small pilot, then scale up.

  3. Replace or retire older devices that can’t be upgraded.

  4. Harden your setup - follow NCSC or Microsoft security baselines.

  5. Train your team - make sure everyone’s ready for the new environment.

 

If upgrading everything at once isn’t possible, Microsoft offers temporary Extended Security Updates (ESU) - but these are short-term fixes, not long-term solutions.

 

In Short

 

Running Windows 10 after October 2025 is like driving without insurance: it might work, but it’s a big gamble.


By upgrading to Windows 11, you’re not just keeping up - you’re protecting your business, your data, and your customers.

 

Now’s the time to make your plan. Don’t wait to secure your systems.
