Microsoft Windows users are advised to perform a crucial computer update their machines. The move is aimed at protecting against harmful viruses and malware and failure to do so will leave your machine “exposed”.

The alert follows the discontinuation of support for Windows 10, which means it will no longer receive automatic security and feature updates. Kian Rogers, a Practitioner Cyber Security Professional (PraCSP) and Penetration Tester at SecQuest, explained that such changes have happened because Windows 10 has officially reached its end-of-life stage.

As a result, users are encouraged to upgrade to Windows 11, provided their device is compatible with the new operating system. “Windows 10 has officially reached end-of-life, which means Microsoft will no longer provide security updates,” Mr Rogers said. “Any newly discovered vulnerabilities will go unpatched, leaving users increasingly exposed to attacks over time.

“For those unable to upgrade to Windows 11, Microsoft is offering its Extended Security Updates programme, giving an additional year of security fixes.” While typically available through a paid subscription, the Windows 10 Consumer Extended Security Updates (ESU) program is currently being offered for one year at no cost to ‘home users’.

This specifically describes people who sign in with a Microsoft account, who can subsequently receive critical security updates until October 13, 2026. Mr Rogers added: “Wherever possible, I recommend protecting your information and privacy from hackers and unauthorised access, so enrolling in the ESU program will help you think on the best next steps for you and your data.”

Beyond this, it’s also worth noting that users of Windows versions prior to 10, such as 7, 8, and Vista, have been out of support for a significantly longer period and are even more vulnerable to cyber threats.

Official guidance from Microsoft has previously advised: “While you could continue to use a PC running Windows 10, without continued software and security updates, your PC will be at a greater risk for viruses and malware.

“After this date, we recommend upgrading to a version of Windows that is still supported. A new device that can run Windows 11 makes for an easy transition and a great experience.”

If you’re interested in purchasing a new Windows 11-compatible PC, it may be worth considering one of Microsoft’s trade-in and recycling schemes. These are offered by many of the company’s partners, including various retailers and PC manufacturers, and can help you earn some extra cash.

Microsoft added: “This resource can help you learn the trade-in value of your used device. You can also return and recycle your device responsibly with our end-of-life management and recycling initiatives.”
