Hi Koh Jun Hao,

The recommendation to use the Volume Activation Management Tool is the definitive, official Microsoft protocol for offline licensing in air-gapped environments. Because traditional phone activation and the self-service web portal have been heavily restricted for certain OEM channels, proxy activation via this utility is the required enterprise solution. You deploy this tool, which is bundled within the Windows Assessment and Deployment Kit, on an internet-connected workstation to securely negotiate with Microsoft's servers.

To execute this protocol, you extract your offline endpoints' hardware Installation IDs into a Computer Information List file, which carries a CILX extension. After transferring this file via removable media, the connected proxy host retrieves the Confirmation IDs and embeds them back into the payload. When you return this updated file to the offline device, the system utilizes the native Software Licensing Management Tool, located at C:\Windows\System32\slmgr.vbs, to process the activation. This script binds the Confirmation ID directly into the system registry hive at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform, permanently validating the OEM license against the hardware. If the procedure fails and returns a licensing error code such as 0xC004F050, it indicates an invalid or channel-restricted product key, requiring you to contact your hardware distributor for keys specifically provisioned for offline deployment.
