Microsoft has officially announced that support for Windows 10 will end on 14 October 2025. While that may seem distant, the reality is that businesses across Australia need to start preparing now.
This change affects more than just IT departments – it has implications for cybersecurity, compliance, operations, and even procurement. Delaying planning could leave your organisation vulnerable, under-resourced, or unprepared for inevitable supply chain pressure.
This article outlines what end of support actually means, what risks are involved, and how to get ahead of the 2025 deadline.
When Microsoft ends support for an operating system, it stops releasing:
In other words, any device still running Windows 10 after October 2025 will no longer receive protection against new threats, compatibility with future software, or help from Microsoft.
For businesses, this means continuing to use Windows 10 could pose serious operational and financial risks.
Without regular updates, Windows 10 machines will be vulnerable to new malware, ransomware, and cyberattacks. Even if your antivirus software is up to date, unsupported systems become easier targets for hackers.
For industries handling sensitive data – like finance, aged care, legal, or healthcare – the risks of a breach could involve compliance violations, reputational damage, or legal action.
Microsoft will offer Extended Security Updates (ESUs) for businesses that choose to delay upgrading. But this comes at a high and escalating cost, with per-device fees expected to double each year through 2028.
This means that maintaining unsupported systems is not only risky – but increasingly expensive.
Many businesses will need to replace hardware that doesn’t meet Windows 11’s requirements (such as TPM 2.0, Secure Boot, and newer CPUs). As more organisations rush to upgrade in 2025, demand for compatible devices will skyrocket.
This creates two problems:
We saw similar challenges during the COVID-19 pandemic when remote work caused mass hardware shortages. The Windows 10 end-of-life period is likely to repeat this pattern.
The impact of end-of-support spans multiple areas of a business:
To avoid disruption and rising costs, businesses should begin preparing as early as possible. Here’s where to start:
Identify how many of your devices are running Windows 10 and whether they meet Windows 11 requirements.
Use Microsoft’s PC Health Check Tool or work with an IT partner to determine which machines need to be replaced.
Procure new devices early to avoid supply chain delays. Aim to complete upgrades before Q3 2025.
Include time for staff onboarding and system testing, especially in businesses with older workflows or custom software.
Trusted IT providers can manage fleet audits, procurement, Windows 11 deployment, and ongoing support.
