No, you cannot use a single Windows Server license key to activate multiple servers. Each Windows Server license key is typically associated with a specific server and allows for the activation of a single instance of Windows Server.
When you purchase a Windows Server license, it is usually tied to the hardware or virtual machine (VM) on which it will be installed. Microsoft's licensing terms typically require a separate license for each server or VM running Windows Server.
Using the same license key on multiple servers would violate the licensing terms and can result in licensing compliance issues. It's important to ensure that you have the appropriate number of licenses to cover each server or VM running Windows Server.
