Windows Server CAL 2025
Windows Server is the cloud-ready operating system that supports your current workloads while introducing new technologies that make it easy to transition to cloud computing when you're ready. A Client Access License (CAL) is required for each user or device that accesses Windows Server or Windows Datacenter server software. This license is for one user CAL.

The licensing rules that actually matter here.
Windows Server Standard and Datacenter are licensed per core: minimum 16 cores per server and 8 per processor, sold as core packs.
Every user or device that touches the server also needs a Windows Server CAL; Remote Desktop use needs RDS CALs on top.
Send us your host and user counts with the quote request — we confirm the core and CAL math before you pay for anything.
