Windows 10 EOL Comes Around Again

PERTH, WA — If you’re still seeing the familiar Windows 10 taskbar on your screen, you’re part of a shrinking club. As we hit the middle of 2026, the "safety net" for one of the world’s most popular operating systems is beginning to fray, leaving millions of Australians facing a digital deadline.

We are now officially in the final stretch. While the "official" end of free support passed us by in late 2025, Microsoft’s Extended Security Update (ESU) program has been the only thing keeping those systems secure. But with October 13, 2026, fast approaching, that lifeline is about to be cut.

The June Hurdle: A Digital "Lock-Out"

​Before we even reach the October deadline, a critical technical hurdle has arrived - the original Secure Boot certificates—the digital "keys" that ensure your computer boots up safely without being hijacked by malware—are set to expire.
​
For users enrolled in the paid ESU (extended security updates) program, Microsoft is already pushing out new "2023 UEFI CA" certificates to keep things running smoothly. However, if you’re running "naked" Windows 10 without those updates, June could mark a turning point where your system's fundamental integrity is no longer guaranteed.

The "Security Tax": A Costly Choice​

For the business world, staying on Windows 10 is about to get a lot more expensive. Microsoft is using a "doubling" price strategy to nudge users toward Windows 11:
​

• Year 1 (Current): Approx. AU$105 per device.
• Year 2 (Starting Nov 2026): Jumps to AU$210+ per device.
• Year 3: Expected to skyrocket to over AU$400.

For home users, the situation is even more precarious. The 12-month "Free ESU" deal offered to many individuals is a one-time gift. As of now, Microsoft has remained silent on whether home users will even be allowed to pay for a "Year 2" extension, leaving many facing a total security blackout this spring.

Your Four Paths Forward

If your PC doesn't meet the strict hardware requirements for Windows 11 (like the TPM 2.0 security chip), you have four main options as we head into late 2026:
​

1. The Hardware Refresh: By now, PCs that can't run Windows 11 are nearly eight years old. For many, it’s simply time to trade in the old silicon for a modern machine.
2. The Linux "Lifeboat": Many are jumping ship to Linux distributions. These free operating systems can breathe another five years of life into old hardware, provided you're willing to learn a new way of working.
3. Third-Party "Mechanics": Services like 0patch have stepped in as independent software mechanics, promising to provide unofficial "micropatches" for Windows 10 until at least 2030.
4. The Air-Gap: For PCs used for specific tasks—like running a CNC machine or an old arcade cabinet—the safest bet is to simply unplug the internet. A computer that isn't online can't be hacked from across the globe.

The Bottom Line

Windows 10 has been a workhorse since 2015, but its legendary run is ending. Whether you're a small business owner or a casual browser, the next few months are your window to decide: will you pay the "security tax," learn a new system, or finally say goodbye to the Start menu you've used for a decade?
