Windows 10 life support ends Oct. 14. Here’s what will happen.

Microsoft’s Windows 10 life support ends tomorrow, Oct. 14. After that, the tech giant will no longer provide free security updates, bug fixes, or technical support for the operating system.

That might sound alarming — especially to the millions of users around the globe who still use Windows 10. But don’t panic. Your computer won’t suddenly stop working, and you don’t have to upgrade to Windows 11 (though Microsoft would certainly prefer that you did).

So, what happens now?

You can still use Windows 10, but once cumulative updates stop, your system will gradually become more vulnerable. Without new patches, hackers can exploit security holes that go unaddressed — putting your data at risk as you browse the web, check email, or do online banking.

It’s not all doom and gloom, though. Microsoft Defender Antivirus will continue receiving virus definition updates until 2028, offering a basic layer of protection. However, the operating system itself won’t get critical security fixes, meaning antivirus alone won’t be enough to keep your device fully secure.

And over time, there’s another problem: compatibility. As developers increasingly focus on Windows 11, older apps, software, and even websites may stop running smoothly on Windows 10. Hard to believe, but the "modern" OS is already a decade old.

If you’re running an older computer that can’t handle Windows 11, there’s still a way to stay secure without buying a new PC. Microsoft is offering enrollment in its Extended Security Updates (ESU) program, which provides critical security patches for an additional year, through October 13, 2026.

Originally designed for businesses, the ESU program has now been expanded to regular users. However, it’s meant only as a stopgap. ESU won’t deliver new features or performance fixes, just essential security updates.

You can enroll for free if you use the Windows Backup app to upload your files to OneDrive, or if you’ve earned at least 1,000 Microsoft Rewards points. Otherwise, access to ESU costs a one-time fee of $30. Enrollment is open now and will remain available until October 13, 2026.
