Windows 10 end of support, explained for New Zealand business

On 14 October 2025, Microsoft stopped supporting Windows 10. There was no shutdown and no dramatic switch-off. Machines running Windows 10 still turn on and still work. What changed is quieter and more important: Microsoft no longer ships security updates, bug fixes or technical support for the operating system. Every new vulnerability discovered from that date forward stays unpatched on a standard Windows 10 device, indefinitely.

For a home user that is a manageable risk to weigh up. For a business, it is a different story. An unpatched operating system is the single easiest way for an attacker to get a foothold, and it is exactly the kind of gap a cyber insurer will ask about at renewal. The good news is that this was a known date, the path forward is well understood, and with a bit of planning the move is straightforward. This page lays out what end of support means, your options, and how Belton helps New Zealand businesses make the change calmly.

1. Upgrade eligible machines to Windows 11

If a device meets the Windows 11 hardware requirements, upgrading it is usually the simplest and cheapest move. Windows 11 needs a reasonably recent processor, 4GB or more of RAM, UEFI with Secure Boot, and a TPM 2.0 security chip. Most business-grade machines bought in the last four or five years qualify. The upgrade keeps your files and applications in place and brings the device back under full support.

2. Replace machines that cannot make the jump

Older hardware, and some consumer-grade machines, simply do not meet the Windows 11 bar. Forcing the upgrade onto unsupported hardware is not worth the instability. For those devices the right answer is a planned replacement with a business-grade laptop or desktop that ships with Windows 11, set up to your standard build. We help you choose the right machines and can spread the cost through IT asset finance rather than a single capital hit.

3. Bridge with Extended Security Updates, briefly

Microsoft offers Extended Security Updates, a paid programme that keeps critical security patches flowing to Windows 10 for a limited time. For business devices this can run for up to three years, with the price rising each year by design. It is a bridge, not a destination. It buys time for a device you genuinely cannot replace yet, while you plan the proper move. We help you decide where a short ESU bridge is worth it and where it is just delaying the inevitable at a premium.

The right plan is rarely one option for the whole fleet. It is the right option for each machine, on a timeline you control.
