Windows 10 ESU: What Actually Happens in October 2026

Plenty of articles still say that Windows 10 Extended Security Updates (ESU) for home users end on 13 October 2026. That is out of date. Microsoft’s official pages now say the consumer ESU program runs until 12 October 2027. October 2026 still matters, though, because several other Microsoft products really do reach end of support this month.

Here is what Microsoft’s own sources confirm, and what to do about it now.

A quick recap

Windows 10 support ended on 14 October 2025. Since then, Windows 10 devices without ESU no longer receive security updates. They keep working, but newly discovered vulnerabilities stay unpatched.

ESU keeps delivering security updates rated critical and important. It is paid, or free under certain conditions. It does not include new features, non-security fixes or general technical support.

Consumer ESU: extended to 12 October 2027

Consumer ESU was originally due to end on 13 October 2026. In late June 2026, Microsoft quietly updated its documentation and added a year. Both the consumer ESU page and the end-of-support page now give 12 October 2027 as the end date, and devices already enrolled keep receiving updates until then.

What Microsoft’s consumer ESU page says:

• How to enroll: free by syncing your PC settings with Windows Backup, by redeeming 1,000 Microsoft Rewards points, or by a one-time purchase of US$30 (or the local currency equivalent, plus tax).
• Device requirements: Windows 10 version 22H2 (Home, Pro, Pro Education or Workstations) with the latest updates installed, including the licensing preparation package KB5126256.
• Account: you need a Microsoft account that is an administrator on the device. Child accounts aren’t allowed.
• Not eligible: kiosk-mode devices, devices joined to Active Directory or Microsoft Entra, and devices managed by MDM. Entra-registered devices are allowed.
• Coverage: one ESU license covers up to 10 devices.
• Enrollment window: open until the program ends on 12 October 2027.

Microsoft also notes that enrollment options and timing may differ by region, such as in the European Economic Area.

Commercial ESU works differently

Work devices that are domain-joined or managed through MDM can’t use the consumer program. Organizations buy commercial ESU through Volume Licensing. Microsoft Learn sets out these terms:

• US$61 per device for year one, and the price doubles each year, for up to three years after end of support.
• It’s sold in whole years only, and it’s cumulative: an organization joining in year two still pays for year one.
• Each year has its own activation ID (Year 1, Year 2 and Year 3), so IT teams need the next year’s license and activation in place.
• Windows 10 running in Windows 365, Azure Virtual Desktop or Azure VMs gets ESU at no extra cost.

As of writing, we found no official change to commercial ESU linked to the June 2026 extension. That extension applies to the consumer program only.

What actually ends around October 2026

These dates come from Microsoft Learn lifecycle pages:

Product	End of support
Windows 10 Enterprise 2016 LTSB	13 October 2026
Office 2021 (Home & Student, Home & Business, Professional)	13 October 2026
Windows 10 Enterprise LTSC 2021	12 January 2027
Windows Server 2016	12 January 2027
Windows 10 Enterprise LTSC 2019	9 January 2029
Windows 10 IoT Enterprise LTSC 2021	13 January 2032

The lifecycle pages show times in Pacific Time. LTSC and LTSB editions have their own lifecycles and aren’t tied to the Windows 10 Home and Pro end date. So production machines, point-of-sale terminals or industrial PCs on LTSB 2016 need attention now. Windows Server 2016 has about three months left.

What to do now

1. Take inventory. List every device still on Windows 10, including edition and version. Separate personal devices, managed work devices and LTSC/LTSB machines. Include servers and machines nobody touches day to day.

2. Choose a path for each device.

• Personal devices: enroll in consumer ESU if you haven’t yet. It gives you breathing room until October 2027.
• Work devices: weigh the cost of commercial ESU against upgrading. Because the price rises every year, treat ESU as a bridge, not a destination.
• LTSB 2016 and Windows Server 2016: plan a move to a supported release.

3. Check Windows 11 readiness. The official minimums are a compatible 64-bit processor at 1 GHz or faster with at least 2 cores, 4 GB RAM, 64 GB storage, UEFI firmware with Secure Boot, TPM 2.0, DirectX 12 graphics with a WDDM 2.0 driver, and a 720p display larger than 9 inches. The PC Health Check app will tell you whether a device qualifies. Upgrading from Windows 10 requires version 2004 or later.

4. Isolate what can’t be updated. Any machine that has to stay on an unsupported system should sit on its own network segment, with restricted internet access, and should not be used for email or web browsing.

5. Back up before you migrate. OS upgrades, hardware swaps and clean installs all carry a risk of data loss. Make sure you have a restorable copy of data and settings before you start.

Why backup matters during the transition

While some of your devices are still on Windows 10, a separate backup helps in two ways. It protects data during migration, and it gives you a way back if an older machine is hit by malware or ransomware.

Cloudku Cyber Protection, built on Acronis, can help here:

• Backup for PCs/workstations, servers and VMs.
• A separate cloud backup copy stored in an Acronis data center in Indonesia.
• AES-256 encryption.
• AI-based anti-malware and anti-ransomware.
• Unlimited devices, priced by storage capacity.

See the available options on the Cyber Protection plans page.

The bottom line

Consumer Windows 10 ESU does not end in October 2026. According to Microsoft, it runs until 12 October 2027. Commercial ESU remains a paid, year-by-year program whose price doubles each year. The products that really do reach end of support on 13 October 2026 are Windows 10 Enterprise 2016 LTSB and Office 2021. Use the extra time to inventory, upgrade and back up rather than to put things off.
