Standard vs Datacenter
Standard covers two VMs. Planning four to six or more VMs on one host, or Storage Spaces Direct? Windows Server 2025 Datacenter is the better value. Our in-depth Windows Server 2025 Standard guide covers every new feature and the full edition comparison.
How to Install and Activate
- Download the Windows Server 2025 ISO from the Microsoft Evaluation Center and install the Desktop Experience or Server Core option.
- Evaluation installs must be converted before a retail key will activate. Open an elevated Command Prompt and run:
DISM /Online /Set-Edition:ServerStandard /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula, then restart when prompted.
- If the server is already a full (non-evaluation) installation, enter the key under Settings → System → Activation or run
slmgr /ipk followed by slmgr /ato.
- Activation is online, so make sure the server is connected to the internet.
Tip: an evaluation edition that has already been promoted to a domain controller can't be converted with DISM. Convert first, then promote, or demote it before converting.
Do You Need Client Access Licences?
Yes. The server licence lets you run Windows Server; every user or device that connects to it also needs a Windows Server CAL. If people will use Remote Desktop to run apps or desktops on the server, each user or device additionally needs an RDS CAL, such as our RDS Device CALs.

Windows Server 2025 Standard Retail FAQ
Can I run more than two VMs with Standard?
Yes, by licensing all the server's cores again with another Standard licence, which adds two more VMs. For many VMs, Datacenter is cheaper.
Can I upgrade my Server 2022 in place?
Yes. Windows Server 2025 supports in-place upgrades from Windows Server 2012 R2 and later. Take a full backup first.
Does it work on Server Core?
Yes. The same key activates both Server Core and Desktop Experience installations.
What if my server has more than 16 cores?
Every physical core must be licensed. Servers with more than 16 cores need additional core licences.
Is hotpatching included?
Windows Server 2025 supports hotpatching, but it requires connecting the server to Azure Arc and a separate paid hotpatch subscription.
