Frequently Asked Questions
What is a Windows Server 2025 Essentials Reseller Option Kit?
A Reseller Option Kit (ROK) is a licensing option designed for OEM partners and resellers. It provides Windows Server 2025 Essentials at a reduced cost when bundled with qualifying hardware. The ROK format ensures the software is tied to the server hardware for which it was purchased, making it ideal for pre-configured server solutions.
Is this a perpetual license or subscription?
This is a perpetual license. You purchase it once and own it indefinitely—no recurring subscription fees, no annual renewal costs. The license remains valid as long as you own the software, providing long-term cost predictability for your business.
How does 10-core licensing work in Windows Server 2025 Essentials?
The 10-core license grants you the right to run Windows Server 2025 Essentials on server hardware with up to 10 processor cores. This applies whether you deploy on a single physical server or across multiple virtual machines on a hypervisor, providing deployment flexibility for growing SMB environments.
What does ESD (Electronic Software Delivery) mean?
ESD means you receive the software digitally rather than on physical media. Upon purchase, you'll receive download links and license keys via email, enabling immediate installation and deployment without waiting for physical shipment.
