Windows 10 ESU Year 3 — the third and final year of Extended Security Updates (2027–2028). Requires ESU Year 1 and 2.
Windows 10 ESU — Year 3 (2027–2028)
The third and final year of Extended Security Updates for Windows 10. The last phase of protection — critical security patches from October 2027 to October 2028. Requires prior activation of ESU Year 1 and Year 2.
Why choose ESU Year 3?
- Your last chance for protection — after Year 3, Windows 10 will no longer receive any security updates
- Full 3 years of protection — from October 2025 to October 2028 with all security updates included
- Maximum time for migration — 3 extra years to prepare your infrastructure for Windows 11
- Cumulative program — includes all updates from Year 1, 2, and 3
Final security updates
The last year of monthly Patch Tuesday updates for Windows 10. After October 2028, no further updates will be available — not even paid ones.
Full 3-year cumulative coverage
The Year 3 key gives you access to the complete set of updates released since October 2025. Three years of protection in one continuous update program.
Secure Windows 10 phase-out
Year 3 gives businesses a final deadline — until October 2028 — to complete migration away from Windows 10. After that date, migration becomes absolutely essential.
Compliance until the very last day
Maintain compliance with NIS2, GDPR, ISO 27001, and security audits throughout the transition period — right up to full migration to Windows 11.
Final purchase opportunity
Year 3 is the final ESU year available. Microsoft does not plan a fourth year — after October 2028, Windows 10 will permanently lose support.
Migration cost analysis
The full ESU package (Year 1+2+3) costs €2,157 per device. Compare that with the cost of new hardware + a Windows 11 license + data migration to choose the optimal time to switch.

Frequently Asked Questions
What happens after October 2028?
Windows 10 will permanently lose all support. No security updates will be available — neither free nor paid. Every Windows 10 PC will become vulnerable to new threats. Migration to Windows 11 (or a newer version) will be absolutely necessary.
Can I buy all 3 years at once?
Yes — you can buy Year 1, 2, and 3 license keys at the same time. Activate them sequentially (first Year 1, then 2, then 3). The total cost of the full package is €2,157 per device — €309 + €619 + €1,229.
Why does Year 3 cost as much as €1,229?
Microsoft applies year-by-year price increases (€309 → €619 → €1,229) to encourage organizations to migrate. This is the official pricing policy — prices are identical across all authorized resellers.
Can I buy Year 3 without Year 1 and 2?
No. The ESU program is strictly cumulative. You must own and activate Year 1 and Year 2 before you can activate Year 3. Microsoft requires sequential activation on each device.
Is it worth buying ESU, or is it better to buy Windows 11 right away?
It depends on your situation. If your hardware supports Windows 11 (TPM 2.0, Secure Boot), migration is more cost-effective in the long term. If you have older hardware without TPM 2.0 or software compatible only with Windows 10, ESU is the only way to maintain security without replacing your hardware.
Delivery and activation
Your ESU key is delivered instantly by email after payment is confirmed — usually within 5 minutes. You will receive detailed step-by-step activation instructions (slmgr/GPO).
