Windows 10 Extended Security Updates (ESU) is a paid programme from Microsoft that provides continued security patches after the Windows 10 end of support date. While it offers a temporary safety net, it is important to understand the costs, limitations, and whether it is the right choice for your business.
Here is how the Windows 10 ESU programme works:
- Year 1 — approximately $61 (around £50) per device per year.
- Year 2 — the cost doubles to approximately $122 per device.
- Year 3 — doubles again to approximately $244 per device, after which no further updates are available.
The Windows 10 ESU UK programme is best suited for organisations that:
- Have a small number of legacy devices that cannot yet be replaced
- Need additional time to complete a migration project
- Run specialist software that requires Windows 10 compatibility testing before upgrading
However, there are significant drawbacks. ESU only covers security patches — no new features, no bug fixes, and no technical support. The escalating annual cost means that over three years, you could spend more on ESU than on new hardware running Windows 11. It is a temporary measure, not a long-term solution.
For most businesses, upgrading to Windows 11 or moving to cloud-based desktops is more cost-effective and secure. Connection Technologies can audit your device estate, identify which machines need replacing, and manage the entire migration process. Get a quote for your Windows migration.
