Windows 10 Security Updates Now Run to October 2027: How to Enrol, and What to Do Before They End

Written by the Yorozuya IT editorial team, based in Japan. Menus, apps, and rules change, so check the date.

Short answer

For most of 2025 the message about Windows 10 was simple: support ends on 14 October 2025, and a one-year bridge ends on 13 October 2026. That date has now moved. If you read an older article saying free updates stop in October 2026, it is out of date.

What changed

Microsoft extended the consumer Extended Security Updates (ESU) programme by one year, to 12 October 2027. The news appeared as an editor's note on a Windows blog post and in updated support pages, dated 25 June 2026, rather than in a formal announcement. People already enrolled are continued automatically.

Decision path for a Windows 10 PC: upgrade to Windows 11 if eligible, otherwise enrol in ESU until 12 October 2027 and plan a replacement

What ESU is, and what it is not

ESU provides critical and important security updates for Windows 10 version 22H2. It does not add features, fix ordinary bugs, or bring technical support. Think of it as a seatbelt for an ageing car: worth having while you arrange something better.

Who can enrol

A simple decision path

  1. Does the PC meet the Windows 11 requirements? Run the PC Health Check app. A supported processor, TPM 2.0, and Secure Boot capable firmware are the usual sticking points. If yes, upgrade. It is free and ends the ESU question.
  2. If not, enrol in ESU now. There is no benefit in waiting, and enrolling does not stop you upgrading later.
  3. Set a date to leave. Treat 12 October 2027 as the deadline for a replacement PC, or for moving to another supported operating system.
  4. Reduce exposure in the meantime. Keep your browser updated, use a standard (non-admin) account for daily work, keep backups, and avoid running the old PC for high-risk tasks.

Why the extension matters for security

Unsupported systems are a favourite target. Attackers often reuse flaws that were patched years earlier, as in the case of Synology NAS ransomware that exploited a flaw patched in 2024. An unpatched PC is exposed in the same way: the weakness is public, and only the fix is missing.

FAQ

My PC is in Europe. Is it still free?

In 2025 Microsoft offered European Economic Area users free enrolment without the Windows Backup requirement. Whether that route continues unchanged after the extension is not clear from the sources we reviewed, so check Microsoft's current ESU page for your country.

What happens if I do nothing?

The PC keeps working, but it stops receiving security fixes. Any new vulnerability stays open on that machine, which matters most for devices used for email, banking, and browsing.

Does one licence cover several PCs?

Microsoft says an ESU licence can be used on up to 10 devices once you enrol, tied to the Microsoft account used to enrol.

Can I just install Windows 11?

If the PC meets the requirements, yes, and the upgrade is free. Run the PC Health Check app to see. Many older machines fail on the processor or TPM requirement.
