How to set up a KMS activation server suitable for Windows 11 operating system clients within our company?

To set up a Key Management Services (KMS) activation server suitable for Windows 11 clients, you will need to follow these steps:

1. Install the Volume Activation Services Role: On your Windows Server, you need to install the Volume Activation Services role. You can do this by running the following PowerShell command in an elevated session:

      Install-WindowsFeature -Name VolumeActivation -IncludeManagementTools
   

2. Configure Windows Firewall: Ensure that the Windows Firewall allows KMS to receive network traffic on TCP port 1688. You can configure this by running:

      Set-NetFirewallRule -Name SPPSVC-In-TCP -Profile Domain,Private -Enabled True
   

3. Use the Volume Activation Tools Wizard: Open the Volume Activation Tools wizard by running vmw.exe. Follow these steps:
   • Select Next on the introduction page.
   • Choose Key Management Service (KMS) as the activation type and enter localhost for the server.
   • Install your KMS host key by entering the product key for your organization and select Commit.
   • After the product key is installed, select Next to activate the product. Choose the product you want to activate and select the activation method (e.g., Activate online).
4. Complete the Configuration: After successful activation, ensure that the KMS host configuration is correct. If needed, you can manually create SRV records to publish the KMS host.
5. Activation Threshold: Note that KMS requires a minimum number of computers to be connected for activation. For Windows clients, the threshold is 25 unique connections, while for Windows Server, it is 5 unique connections.

By following these steps, you will set up a KMS activation server that can activate Windows 11 clients in your organization.
