You can use shared or dedicated CPU for your Windows Server at TransIP. The price of the Windows Server license is higher for a VPS with dedicated CPU cores than for a VPS with shared cores. This difference is in the way Microsoft calculates the price for Windows Server licenses:
Microsoft calculates a monthly Windows Server license fee based on the total number of CPU cores of the hypervisor hosting your VPS. When using dedicated CPU cores CPU cores are reserved for you on a hypervisor that's reserved for VPSs with dedicated cores.
As a result, there can be fewer VPSs with dedicated cores on one hypervisor than with VPSs with shared CPU cores. This ensures that the costs of Windows licenses can be spread over fewer VPSs, resulting in a higher average license price.
That brings us to the end of this article about the difference in price of Windows Server licenses between shared and dedicated cores.
