Staying on Windows 10 in 2026 What End of Support Means and How ESU Buys Time

On 14 October 2025 Windows 10 support ended. Concretely, that means a Windows 10 PC outside ESU now receives no security updates, no feature updates and no technical support from Microsoft. The PC still boots, your apps still run, and nothing pops up to stop you working. The change is invisible — and that is exactly the danger.

Security updates are not decoration. Every month, researchers and criminals alike learn about fresh holes in Windows. Supported systems get those holes patched; an out-of-support Windows 10 keeps every hole it has today plus every one discovered from now on, forever. The risk does not jump in one day. It compounds, quietly, month after month.

The picture is not all-or-nothing, and honesty cuts both ways:

1. Browsers — Chrome, Edge and Firefox keep their own update cycles and have continued supporting Windows 10 for now, but each vendor will drop it on its own schedule. The browser is your biggest attack surface, so its support window matters almost as much as the OS's.
2. Microsoft 365 apps — Microsoft has said Office apps under Microsoft 365 keep receiving security updates on Windows 10 until October 2028, though feature updates stop earlier.
3. Antivirus definitions — Microsoft has continued publishing Defender definition updates for older systems in past transitions, but definitions are not OS patches. They catch known malware; they do not close the holes in Windows itself.
4. Windows itself — outside ESU, nothing. That is the hole the rest of this page is about.

The Extended Security Updates (ESU) programme is Microsoft's official way to keep a Windows 10 PC patched a while longer. For home users the offer is simple to state and narrow in scope:

1. What you get: security updates for issues Microsoft rates critical and important — nothing else. No new features, no design fixes, no technical support, no non-security bug fixes.
2. What it costs: there are three enrollment routes — free if you sync your PC settings using Windows Backup with a Microsoft account, 1,000 Microsoft Rewards points, or a one-time $30 payment (local pricing varies). One enrollment covers up to 10 devices on the same Microsoft account.
3. What it needs: Windows 10 version 22H2, fully updated, and sign-in with a Microsoft account. Enrollment appears inside Settings → Update & Security → Windows Update as an "Enroll now" offer.
4. How long: the consumer programme was first announced to run to October 2026, and Microsoft later extended it — enrolled PCs are reported covered until October 2027. Check the Windows Update page on your own PC for the end date that applies to you, and treat that date as a hard deadline, not a suggestion.
