You don’t download a separate “Windows 11 Pro for Workstations” ISO. You download the normal Windows 11 ISO from Microsoft,
install Windows, then upgrade/activate to Pro for Workstations using a valid Workstations license (product key/digital license).
Windows 11 Pro for Workstations is Windows 11 Pro, but built for high-end PCs that do heavy work:
large video projects, 3D rendering, big datasets, lots of virtual machines, and (sometimes) local AI workloads.
It supports up to 4 CPU sockets and 6 TB of RAM, and adds workstation-focused features like
ReFS and SMB Direct (RDMA) for very fast storage/network setups.
Do you actually need Pro for Workstations?
Good reasons to get it
- You have a workstation motherboard with 2–4 CPU sockets.
- You need more than 2 TB RAM (rare, but some workstations do).
- You have an RDMA-capable network setup and want SMB Direct performance.
- You want ReFS for specific storage workflows (not for everyone).
When regular Windows 11 Pro is enough
- You have a normal PC (1 CPU socket) and 16–128 GB RAM.
- You’re mainly gaming, office work, browsing, or light creative work.
- You don’t use RDMA networking or workstation storage features.
| Feature | Windows 11 Pro | Windows 11 Pro for Workstations |
|---|---|---|
| RAM limit | Up to 2 TB | Up to 6 TB |
| CPU sockets | Up to 2 | Up to 4 |
| ReFS support | No (NTFS only) | Yes |
| SMB Direct (RDMA) | No | Yes |
| Persistent memory (NVDIMM-N) | No | Yes (only if your hardware supports it) |

Key features (what you’re really paying for)
Higher hardware limits
Supports up to 4 CPU sockets and 6 TB RAM. This matters for true multi-socket workstations and extreme memory workloads.
SMB Direct (RDMA)
Designed for high-speed network file access using RDMA-capable adapters (popular in some studios and lab environments).
ReFS + persistent memory support
Adds ReFS and support for persistent memory (NVDIMM-N). These are only useful if your workstation hardware actually supports them.
Most regular PCs won’t.
