Questions about Windows Server licenses
What does Windows Server 2025 Datacenter activate?
It activates the edition named on this page, on 1 server. Other editions and versions are separate products, each with its own page.
Do I need RDS CALs to use Remote Desktop?
RDS CALs are separate products, sold in packs of 50 as User CALs or Device CALs. Microsoft’s licensing terms say which users and devices need them: check them for your setup. You can find the packs for each version in Windows Server license keys.
Which Windows Server version should I buy?
The one your applications support. Compare the support end dates above before you decide.
Can I reinstall Windows Server or move the license to another server?
RETAIL Licenses can’t be reused. If you later reinstall the software or the operating system, or change the server’s hardware, that activation can’t be used again, and our warranty doesn’t cover it. Your statutory rights are not affected.
- Download Windows Server 2025 from the Microsoft Evaluation Center: the link is in the Download tab.
- Install the edition you bought, with Desktop Experience. Activate it before making the server a domain controller.
- Open Command Prompt as administrator and run this command with your license key:
DISM /online /Set-Edition:ServerDatacenter /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula
Restart the server when it asks you to.
