Can I Use My Own Windows License on My Contabo Server?
If you have your own windows license, it can only be used on a Dedicated Server. It is not possible to use your own Windows license on a Virtual Private Server (VPS) or a Virtual Dedicated Server (VDS).
Due to the license agreement between Contabo and Microsoft, it is not possible to use your own Windows license on a VPS or VDS. Instead, you must use the Windows Server license provided by Contabo. The terms of the license agreement require Contabo to charge a monthly fee for a Windows Server, which is determined by the size of the VPS/VDS you order.
If you have a Contabo dedicated server, you can use your own Windows license on it.
