Windows 10 ESU Year 2 — the second year of Extended Security Updates (2026-2027). Requires a Licensier ESU Year 1 license.
Windows 10 ESU — Year 2 (2026–2027)
Second year of Extended Security Updates for Windows 10. Continued critical security patches from October 2026 to October 2027. Requires prior activation of ESU Year 1.
Why Choose ESU Year 2?
- Continuous protection — another 12 months of critical security fixes after Year 1 expires
- Cumulative program — includes all fixes from Year 1 plus new patches released in Year 2
- More time to migrate — an extra year to plan your move to Windows 11
- Required for Year 3 — if you want the full 3 years of protection, Year 2 is essential
Critical security updates
Monthly Patch Tuesday updates covering critical and important security fixes, providing the same level of protection as in Year 1.
Cumulative updates
The Year 2 license key includes access to all fixes from Year 1. Even if you activate later, you will receive the complete set of patches released since October 2025.
Migration planning
The second year of ESU gives businesses time to migrate their fleet to Windows 11 gradually, without compromising the security of remaining workstations.
Regulatory compliance
Maintain compliance with NIS2, GDPR, ISO 27001, and industry security standards for another 12 months.
Automatic delivery
After activating your original license key, updates are delivered automatically through Windows Update. No manual downloading or patch installation required.
Cost-effective alternative
€619 per device is still significantly cheaper than replacing hardware with a new Windows 11 PC. Ideal for fleets with dozens or hundreds of workstations.

Frequently Asked Questions
Can I buy Year 2 without Year 1?
No. The ESU program is cumulative, so you must first buy and activate ESU Year 1. Only after that can you add the Year 2 license key. Microsoft requires sequential activation.
Why is Year 2 more expensive than Year 1?
Microsoft intentionally increases ESU pricing each year to encourage migration to Windows 11. Year 1 costs €309, Year 2 costs €619 (2x), and Year 3 costs €1229 (2x Year 2). This is Microsoft’s official pricing policy.
What if I activate Year 2 later?
ESU updates are cumulative. Once Year 2 is activated, you receive all patches released since the start of the program in October 2025. You will not miss any fixes, but during any period without an active license key, the PC was not protected.
Can I activate Year 1 and Year 2 at the same time?
Yes, if you have both license keys. Activate Year 1 first using slmgr /ipk, run Windows Update, and then activate Year 2. Protection will be extended until October 2027.
Does ESU cover Microsoft Office and other applications?
No. ESU applies only to the Windows 10 operating system. Applications such as Microsoft Office, Edge, and .NET Framework have their own support and update lifecycles.
Delivery and activation
Your ESU license key is sent instantly by email once payment is confirmed, usually within 5 minutes. You will receive a detailed step-by-step activation guide for slmgr/GPO.
