Frequently Asked Questions
Are these Windows Server keys genuine?
Yes. All license keys sold by LicenceHouse are 100% genuine Microsoft licenses that activate via Microsoft's official servers. We do not sell cracked, pirated, or grey-market software.
What's the difference between OEM and Retail licenses?
OEM licenses are tied to the hardware they are first activated on and cannot be transferred to a new machine. Retail licenses can be transferred if you decommission the original server. Check each product listing for the specific license type.
Do I need a CAL (Client Access License) as well?
Yes — if users or devices will connect to your Windows Server, you will also need Client Access Licenses (CALs). Browse our Access Licences / CALs collection for RDS CALs and more.
Is there a trial before I buy?
Microsoft offers free 180-day evaluation ISOs for most server editions via the Microsoft Evaluation Center. Once you are ready to activate permanently, simply purchase your key from LicenceHouse and enter it into the running system — no reinstallation required.
What payment methods do you accept?
