Important Note:
The ESU for Windows 10 (2025–2026) (2025-2027) (2025-2028) covers a fixed period from October 14, 2025 to October 13, 2026, (2027) (2028) regardless of when it is purchased or activated. This is due to Microsoft’s strict lifecycle policy and deadline structure for Windows updates, which defines ESU coverage windows in advance and does not offer prorated or rolling coverage.
