Should You Upgrade to Windows 11? A Plain-English Guide for Townsville

Windows 10 reached end of life on October 14, 2025. That means Microsoft has stopped releasing security updates for it — leaving any PC still running Windows 10 increasingly exposed to new threats. If you're one of the many Townsville residents or businesses still on Windows 10, here's what you need to know and what your options are.

What "End of Life" Actually Means

End of life doesn't mean your computer stops working overnight. Windows 10 will keep running exactly as it did before. What it means is that Microsoft will no longer release security patches for newly discovered vulnerabilities.

This matters because hackers actively target known vulnerabilities in end-of-life software. The longer you run an unpatched OS, the higher the risk. It's the same reason businesses had serious problems when Windows XP and Windows 7 hit end of life — the machines kept running, but attackers knew exactly which holes to exploit.

Can Your PC Run Windows 11?

This is the first question to answer — and it's where many people hit a wall. Windows 11 has stricter hardware requirements than any previous version of Windows. Specifically, it requires:

• TPM 2.0 — A security chip that most PCs made after 2017 have, but many older machines don't
• 64-bit processor — Any modern CPU qualifies, but very old machines may not
• A compatible CPU — Intel 8th generation or newer, or AMD Ryzen 2000 series or newer
• 4GB RAM minimum (8GB recommended)
• 64GB storage minimum
• UEFI firmware with Secure Boot

How to Check if Your PC Is Compatible

Microsoft provides a free tool called the PC Health Check app. If you're running Windows 10, search for "PC Health Check" in the Start menu — it should already be installed. Run it and it will tell you instantly whether your machine can upgrade to Windows 11.

If you'd rather not do this yourself, bring the machine in and we'll check it for you — no charge.

If Your PC Is Compatible: Should You Upgrade?

Yes — and sooner rather than later. Windows 11 is free for eligible Windows 10 PCs, and the upgrade process has matured significantly since the rocky early days. Most users find Windows 11 runs well on compatible hardware, and the security improvements are real.

A few things to know before you upgrade:

• Back up your data first. The upgrade is generally safe, but you should never update an OS without a backup in place. Use Windows Backup, an external drive, or OneDrive.
• Allow 1–2 hours. The upgrade downloads and installs in the background and requires a restart. Budget time for this.
• Most software will work fine. The vast majority of Windows 10 applications run without issue on Windows 11. Very old or specialist software may need checking.
• The interface has changed. The Start menu is centred, settings are reorganised, and some things have moved. It takes a week or two to adjust but most people adapt quickly.

If Your PC Is NOT Compatible: Your Options

This is the harder conversation — and one we're having with a lot of Townsville clients right now. If your machine can't run Windows 11, you have three options:

Option 1: Buy a New PC

The cleanest solution. A new mid-range Windows 11 PC will be significantly faster than most machines that don't meet Windows 11 requirements, and you get a fresh start with full security support. Budget $800–$1,500 for a good quality business laptop, or $600–$1,000 for a capable home desktop setup.

Option 2: Pay for Extended Security Updates (ESUs)

Microsoft is offering paid Extended Security Updates for Windows 10 — similar to what they did for Windows 7. For individuals, the first year (2025–2026) costs around AUD $50. For businesses, pricing is per device and scales with volume. This buys you time but isn't a permanent solution.

Option 3: Switch to Linux

Not for everyone, but worth mentioning. Modern Linux distributions like Ubuntu or Linux Mint run well on older hardware, are free, and are actively maintained. If your machine is used primarily for web browsing and email, Linux is a genuinely viable option that extends the life of your hardware by years.

What We Recommend for Townsville Businesses

For businesses, staying on Windows 10 without ESUs is not acceptable from a security standpoint. If you have business data, customer information, or financial records on those machines, you have an obligation under the Australian Privacy Act to take reasonable steps to protect it.

Our recommendation:

• Audit your fleet — we can do this for you — and identify which machines are and aren't Windows 11 compatible
• Upgrade compatible machines to Windows 11 now
• Plan replacement for incompatible machines, prioritising the ones that hold the most sensitive data
• Consider Microsoft 365 Business Premium alongside the upgrade — it includes advanced endpoint security that significantly hardens Windows 11 machines
