Windows Server 2025 Standard, 64-Core License with 100 User CALs
Windows Server 2025 Standard is Microsoft’s latest server operating system, built for businesses that want faster performance, stronger security, and a platform that stays reliable for years. This license covers up to 64-core processors and includes 100 User CALs, so you can license your hardware and your users in a single purchase instead of piecing together core packs and client access licenses separately.
Buy it once and own it. There is no annual renewal, no recurring bill, and no license that quietly stops working when a subscription lapses.
What You Get
- Genuine Microsoft license, delivered digitally with an official download link
- 64-core coverage, enough for the vast majority of single-server and dual-socket deployments
- 100 User CALs included, licensing up to 100 named users to legally access the server
- Two activations on this license, so you can run the physical host plus a virtual instance, or two virtual instances (need more? Add another license for two more activations)
- Lifetime license, a one-time purchase with no subscription and no expiration
- Instant delivery, typically within minutes of checkout
- U.S.-based support from real technicians who help you through installation and activation
Why Businesses Choose Windows Server 2025 Standard
Hotpatching for less downtime. Apply security updates to running servers without a reboot, which keeps critical workloads online during patch cycles.
Faster storage and networking. Improvements to Storage Spaces Direct and NVMe handling deliver significantly higher IOPS than previous releases, and native support for modern networking hardware reduces latency across the stack.
Hardened by default. Credential Guard, SMB over QUIC, and Secured-core server capabilities protect against credential theft and lateral movement, with TLS 1.3 enabled out of the box.
Better Active Directory. A higher domain and forest functional level brings 32K database page support and improved replication performance for growing directories.
Ready for hybrid. Connect on-premises workloads to cloud services when you want to, without being forced into a cloud-only model.

Frequently Asked Questions
Is this a genuine Microsoft license? Yes. This is an authentic Microsoft license that activates through Microsoft’s own servers and receives official updates.
What does 64-core coverage mean? The license covers a server with processors totaling up to 64 cores. This is a full server license, not a per-core add-on pack, so you do not need to calculate and purchase core packs separately.
What is a User CAL and why do I need one? Microsoft requires a Client Access License for each user or device that connects to the server. This listing includes 100 User CALs, which license 100 named users to access the server from any number of their devices.
How many activations does this license include? Two activations total. That allows the physical host operating system plus one virtual instance, or two virtual instances. If you need to run additional virtual machines, order another license for two more activations.
Is this a subscription? No. This is a perpetual license. You pay once and the license is yours permanently.
How quickly will I receive it? Delivery is digital and typically arrives within minutes of your order. You will receive your license key along with an official download link.
Can I upgrade from Windows Server 2019 or 2022? Yes. In-place upgrades from Windows Server 2019 and 2022 to 2025 are supported. Our support team can walk you through the process, and a clean installation is always an option if you prefer to start fresh.
