Windows Server 2016 Standard for lightly virtualised environments
Choose the core count that matches the physical server you intend to license. Windows Server 2016 Standard is designed for physical or lightly virtualised workloads and grants rights for up to two operating-system environments when the server is fully core-licensed.
- Standard edition
- 16 or 32 cores
- Up to 2 OSEs
- 64-bit server OS
- CALs sold separately
Purchase boundaries
Quick facts before you select 16 or 32 cores
The selected pack must be sufficient to license every physical core in the server, subject to Microsoft's minimums. Extra core licences may be required for higher-core hardware.
Edition fit
Choose Standard when two virtual workloads are enough
Physical server
Run Windows Server directly on licensed hardware for roles such as file, print, identity or line-of-business services.
Light virtualisation
Use up to two Windows Server operating-system environments after every physical core is licensed.
Cost-conscious deployment
Choose Standard when Datacenter-only storage, networking and unlimited virtualisation rights are not required.
Core licensing
Count the hardware before buying
- 1
Count physical processors and cores
Use the server manufacturer's specifications or firmware tools. Logical processors and Hyper-Threading threads are not physical cores.
- 2
Apply Microsoft's minimums
License at least eight physical cores per processor and at least sixteen physical cores per server, even if the hardware contains fewer.
- 3
Cover every physical core
Select enough core licences for the entire server. To run more than two Windows Server OSEs, fully license the server again for each additional pair or compare Datacenter.

Installation planning
Choose Server Core or Desktop Experience during setup
Windows Server 2016 Standard can be installed as Server Core or with Desktop Experience. Microsoft states that switching between these installation options later requires a clean installation, so confirm application and administration requirements first.
Plan beyond purchase
A perpetual licence is not permanent support
Microsoft's lifecycle page places Windows Server 2016 in extended support through January 2027. Continued use after that date does not mean Microsoft will continue ordinary security updates or product support. Consider Windows Server 2022 or 2025 for a new long-term deployment.
Buyer questions
Windows Server 2016 Standard FAQs
Does a 16 Core licence cover every server?
No. It meets Microsoft's minimum for one server, but a server with more than 16 physical cores requires enough licences to cover every physical core.
How many virtual machines can Standard run?
Standard grants rights for up to two Windows Server OSEs when all physical cores are licensed. Each additional pair requires licensing all physical cores again.
Are Windows Server User CALs included?
Not on this core-licence page. Windows Server CALs are normally required separately for users or devices accessing Standard.
Are RDS CALs included?
No. Remote Desktop Services access normally requires both the appropriate base Windows Server CAL and an additional RDS CAL.
Can I change from Server Core to Desktop Experience later?
Not as an in-place conversion. Microsoft requires a clean installation to change between these installation options.
When does Windows Server 2016 support end?
Microsoft extended support ends in January 2027. Check the official lifecycle page before committing to a new deployment.
