Windows 10 End of Support NZ: What Hamilton Homes & Small Businesses Should Do Now

Windows 10 End Of Support NZ

Last updated: 15 December 2025

Windows 10 reached end of support on 14 October 2025. That means no more free security patches for the operating system. You can (for a limited time) enroll in Extended Security Updates (ESU), upgrade to Windows 11, or replace older devices. This guide explains what each path looks like in New Zealand—and how Tech On Wheels can handle the heavy lifting in Hamilton and across the Waikato.

A man enjoys a productive morning in his modern kitchen, working on a laptop with a sleek design and multiple connections plugged in.

Why this matters (especially in NZ)

Unsupported systems are prime targets for malware, phishing and banking trojans. Many Waikato households and small businesses still run Windows 10 on perfectly good hardware. The question isn’t if you should plan an upgrade—it’s which path gets you there with the least pain, risk and cost.

What changed on 14 October 2025?

• Microsoft ended free security updates for Windows 10 Home/Pro.

• Apps will still run, but the operating system no longer receives fixes for newly discovered vulnerabilities unless you’re enrolled in ESU.

• Microsoft 365 (Office) apps on Windows 10 continue to receive security updates for a limited time to help with transition (details below), but that does not secure the Windows 10 OS itself.

Your three routes (choose the one that fits your situation)

1) Upgrade to Windows 11 (recommended for most)

Best for: PCs that meet Windows 11 requirements (TPM 2.0, supported CPU, 4GB+ RAM, 64GB+ storage, Secure Boot).

Pros

• Fully supported OS with ongoing security patches and features

• Better phishing protections and device encryption on modern hardware

• Smoothest compatibility path for business apps and peripherals

Watch-outs

• Pre-check for app/driver compatibility

• Older peripherals (e.g., USB printers, label makers) may need new drivers

What Tech On Wheels does

• Compatibility check + health report

• In-place upgrade or clean install (as appropriate)

• Full data transfer, profile migration, and post-upgrade tuning

• BitLocker/Device Encryption setup, driver/firmware updates, restore-point, rollback plan

2) Enrol in Extended Security Updates (ESU) – a short-term bridge

Best for: Homes or very small teams that need a few extra months on Windows 10 while planning upgrades or replacing hardware.

What ESU is

• A paid (sometimes discounted) programme that continues critical/important security updates for Windows 10 for a limited period after end of support.

• It doesn’t add new features or app compatibility; it simply buys you time to upgrade safely.

Pros

• Reduces immediate risk while you schedule upgrades

• No workflow changes—your team keeps using Windows 10 temporarily

Watch-outs

• It’s time-limited and not a substitute for upgrading

• You must stay fully patched on the last Windows 10 version and meet the enrolment steps

What Tech On Wheels does

• Verify eligibility, enrol devices, confirm updates apply correctly

• Build your timeline to move to Windows 11 (or replace devices) before ESU ends

3) Replace the device (when upgrade isn’t viable)

Best for: PCs that fail Windows 11 hardware checks or are more than 5–7 years old.

Pros

• Big jump in performance, battery life and security

• Warranty coverage; fewer surprise downtime events

Watch-outs

• One-off hardware cost

• Data migration and software licensing transfers required

What Tech On Wheels does

• Recommend suitable desktops/laptops for home or SMB use

• Stage the new device (Windows 11, drivers, updates, Microsoft 365, printers)

• Zero-downtime cutover: migrate files, browser profiles, email, and passwords

• Secure recycling/e-waste guidance for old equipment

What about Microsoft 365 (Office) on Windows 10?

• Microsoft 365 apps continue to get security updates on Windows 10 for a limited transition period. That helps protect documents and email, but it does not fix OS vulnerabilities.

• Feature updates for Microsoft 365 on Windows 10 taper off earlier than on Windows 11. Translation: even if your Office apps still work, staying on Windows 10 isn’t a safe long-term plan.

Hamilton-focused security reality check

• Scams and phishing are rising: invoice fraud, fake delivery texts, “Microsoft support” cold calls, and MFA fatigue attacks are common in NZ.

• Unsupported Windows 10 machines make incident response harder and recovery costlier for small businesses.

Baseline protections we implement by default

• DNS filtering, SmartScreen hardening, and reputable AV/EDR

• Local admin lock-down, standard user accounts, strong PIN/password policy

• BitLocker or device encryption + recovery key escrow

• Browser security baselines, extension hygiene, safer defaults for macros

Migration checklist (use this even if you DIY)

1. Inventory devices, apps, and peripherals; flag anything business-critical

2. Backup: verify a restorable image + separate file backup (3–2–1 rule)

3. Health check: storage SMART, battery wear, RAM, firmware, drivers

4. Licences: Windows, Microsoft 365/Office, line-of-business apps

5. Decide your path: Upgrade, ESU bridge, or replace

6. Schedule outside business hours; notify staff and customers

7. Cutover: upgrade/replace; migrate data, email, browser profiles, printers

8. Harden post-migration: encryption, updates, security baselines, restore point

9. Document: device tags, serials, warranty dates, admin notes

Pricing examples (typical, simple cases)

Home PC Upgrade Check – from $89 (compatibility check + written report)

Windows 10 → 11 Migration (Home) – from $229 per PC (backup, upgrade, post-tune)

Small Business Fleet Plan (3–10 PCs) – from $179/PC (scheduled cutover, documentation, staff brief)

Final quotes depend on age, storage health, data volume and app complexity.

Frequently Asked Questions (NZ)

Can I keep using Windows 10 safely for a while?You can reduce risk with ESU and strong security settings, but it’s still a countdown. Plan an upgrade or device replacement.

My Office apps still update—am I safe?Those app updates don’t patch Windows 10 itself. You still need an OS plan.

Do I really need TPM 2.0 for Windows 11?Yes—plus Secure Boot and a supported CPU. We’ll check it for you and offer options if your CPU misses the list.

What if my favourite printer or accounting tool breaks on Windows 11?We pre-check and, if needed, stage a rollback plan. Many issues are fixable with updated drivers or vendor patches.

Can you help us avoid scams?Yes—staff training, mailbox rules to catch spoofing, and safer payment verification processes. We also set up simple incident playbooks.
