Windows 10 security updates now run into 2027. Check before replacing your PC.

Microsoft’s current U.S. consumer Extended Security Updates page lists October 12, 2027 as the program’s end date. It says existing enrollment continues automatically. We checked that page on September 27, 2026; this is a practical update on the current policy, not a claim that Microsoft announced the extension today.

Ordinary Windows 10 support ended October 14, 2025. An operating system continuing to start does not mean it is still receiving its normal support. For a home PC that cannot yet move to Windows 11, checking ESU eligibility is a more useful first step than buying a replacement in a panic.

ESU supplies critical and important security updates to eligible enrolled Windows 10 22H2 PCs. It does not add new features or include general technical support. Enrollment and an up-to-date PC matter; simply knowing the deadline has moved is not enough.

Microsoft separately lists security updates for Microsoft 365 on Windows 10 through October 10, 2028. That is a different timeline for the applications, not a promise of Windows 10 operating-system coverage through 2028. Keep those dates separate when planning a replacement.

1. Open Settings → Update & Security → Windows Update. Check the displayed ESU enrollment status and install available updates.
2. If you are not enrolled, follow the official enrollment flow. Microsoft lists settings-sync enrollment at no additional cost, 1,000 Rewards points, or a $30 purchase plus applicable tax in the U.S. Confirm your regional terms.
3. Run Microsoft’s PC Health Check to see whether your existing hardware qualifies for Windows 11. Read the explanation if it does not; do not assume buying another PC is your only route.
4. Keep a separate backup of important files before an operating-system change. Open a few backed-up documents to check that the copy actually works.

Keeping an enrolled, reliable PC can be good value when it still handles your real workload. Use the breathing room to price a suitable replacement and test your essential software. A working email-and-documents machine does not need to become an expensive gaming laptop just because its support plan changed.

Replacement becomes easier to justify when several problems coincide: unreliable hardware, unacceptable battery life, insufficient performance, or an application you need no longer working well. Write down those problems and the cost of fixing them before choosing a budget.

If the PC belongs to an employer or is managed by an organization, ask its IT team. Consumer enrollment is not the same as a commercial support plan. Our advice here is aimed at personal home computers, and we have not checked your individual device.
